Important!
The installation of a rotatable antenna on a tower system is a dangerous and potentially life-threatening task if due care is not taken.
A tower must never be installed in a position where it could fall across power distribution cables in the event of a catastrophic tower failure during a windstorm or earthquake.
The control cable attached to this rotator could, in the event of a nearby or direct lightning strike, carry lethal voltages down the cable and into your home. Yaesu strongly recommends the installation of suitable lightning arrestors on all control cables and coaxial lead-in cables from your antenna installation. See your dealer for details of available lightning-protection devices.
If an electrical storm should be reported in your area, quickly unplug the control cable from the rear of the rotator’s controller box, and disconnect the AC cable from the wall outlet. Disconnect the coaxial cable(s) from the antenna(s) as well. Do this only if the lightning is not in your immediate area, as you could be killed instantly if lightning should strike while you are holding a cable.
If you have any doubts about your ability to install this rotator safely, enlist the services of a professional antenna installation company.

The Yaesu G-800DXA, G-1000DXA, and G-2800DXA are designed to rotate large tower-mounted amateur and professional antenna arrays under remote control from the station operating position. The clamshell rotator design utilizes 98 3/8 inch dual-stacked circumferential ball bearings to distribute the load over the full diameter of the housing. This design minimizes stress and wear, and practically eliminates the possibility of destructive water entry: there is no shaft hole in the top of the housing.
Instead of the usual AC motor drive used in older rotator designs, the G-800DXA, G-1000DXA, and G-2800DXA use a variable-voltage DC motor, obviating the need for a  large starting capacitor with its potential for failure exposed to outside temperature variations. The factory-lubricated rotator unit is housed in melamine resin-coated die-cast aluminum, intended to provide maintenance-free operation under all climatic conditions. A mast alignment gauge on the rotator housing simplifies accurate mechanical alignment during installation.
The handsome desktop controller matches the design of modern transceivers, providing a 360° radial indication of actual antenna bearing azimuth. You can select rotating speeds from 40 to 100 seconds per (360°) rotation (G-800DXA and G1000DXA, G-2800DXA: 50 to 120 seconds per (360°) rotation), and can preset a desired heading for the rotator,  to which it then turns automatically.
In the G-2800DXA model, when a fast rotating speed is selected, special “auto slow start” and “auto slow stop” features avoid sharp jolts to the antenna array and tower.  Activating the rotator causes it to begin turning at a slow speed. As the antenna approaches the desired heading rotation automatically slows before bringing the antenna to a  gentle stop. The operator may select the stopper heading (the bearing through which the rotator cannot be turned) most convenient for his location and operation, allowing full rotation through north, south, or both, if desired. In any case, 90° overlapping rotation allows rotation through the selected stopper heading (450° total rotation).
The rotator is intended for mounting inside a support tower (not supplied), at least 1 meter from the top, with an optional (Yaesu model GS-680U) thrust bearing above.
The G-800DXA and G-1000DXA include one mast clamp and related hardware, plus plug connectors for both the rotator and controller. A five conductor cable of the  necessary length must be supplied by the owner. The G-2800DXA model includes one mast clamp and related hardware, plus a 40 m length control cable, to simplify installation.
The GS-232B Computer Control Unit is available as an option, allowing positioning of the antenna by a personal computer, via an RS-232 serial interface.
Please read this manual carefully before installing the rotator, to acquaint yourself with the procedures that will be required, and to ensure that you have all necessary items for your installation.

Controller Front Panel

1. POWER switch
   Press this switch to turn the controller on to rotate the antenna. Turn it off when the rotator is not in use.

2. LEFT/RIGHT Seesaw Switch
   Press the LEFT side of this switch to rotate the antenna counter-clockwise (CCW). Press the RIGHT side to rotate the antenna clockwise (CW).

3. PRESET Control and START Switch
   Set the PRESET control to the desired antenna heading according to the outer angular scale (180 ~ 270) around this control, then press the (momentary) START switch to activate automatic rotation to the desired heading. You can press the LEFT/RIGHT switch to abort the preset operation.
   Note: If you change the rotator starting position to 0° (N: North), set the PRESET control to the desired antenna heading according to the inner angular scale (0 ~ 90)  around this control.

4. SPEED Control
   Set this control for the desired rotating speed between approximately 30 and 100 seconds per 360° revolution.

5. OVERLAP Indicator
   This red LED glows when the antenna is rotated beyond about 180° (to 270°) from its original installation direction (180°). Check this indicator before rotating the antenna clockwise, and turn the antenna counter-clockwise to the desired position if the indicator is on.

Controller Rear Panel

1. EXT CONTROL Connector
   This 6 pin mini-DIN connector is used for connection to the optional GS-232B Computer Control Unit.

2. SELECT SWITCH
   Set this switch to the “ADJ. MODE” position while calibrating the internal adjustments of the controller. During normal operation, however, set this switch to the  “OPERATION MODE” position.

3. FULL-SCALE ADJ Potentiometer
   This control calibrates the maximum rotation angle (range) of the azimuth indicating the needle to match the maximum angle of the rotator.

4. OVERLAP LED ADJ Potentiometer
   This control calibrates the OVERLAP Indicator to match the azimuth indicating needle.

5. PRESET ADJ (A & B) Potentiometers
   These controls calibrate the angle of the PRESET control on the front panel to match the azimuth indicating needle. Pot. A should be adjusted only near the 180 ｰ positions, and Pot. B only near the 270° (450°) position.

6. OUT VOL ADJ Potentiometer
   This control presets the voltage range at pin 4 of the 6 pin mini-DIN EXT CONTROL Connector, for cali- bration of the A-to-D converter on the (optional) GS-232B  Computer Control Unit.

7. Rotator Control Cable Jack
   The control cable from the rotator connects to this 6 pin jack.

8. FUSE Holder
   This holder requires a 2 A fuse for 117 V AC, and a 1 A fuse for 220 V AC. If the fuse is blown, replace only with a fuse of the same rating.

9. AC Cable
   Connect this cable to the AC mains supply or wall outlet. The AC line voltage must match that on the label.

Antenna Considerations

The types of antennas that can be attached to this product differ widely, depending on the installation method, local terrain, and the maximum expected wind speeds at your location.
The following pages described typical antennas which are acceptable for installation with the G-800DXA, G-1000DXA or G-2800DXA. The discussion below assumes maximum wind speeds of 30 meters per second, and it is recommended that you include a safety margin of at least 40 % to account for higher wind gusts or other factors which might potentially cause damage to your installation.

Pole-Mounted Antennas
Mounting of the rotator on a pole or mast results in a significant de- rating of the size of the antenna which can be mounted, due to the tremendous bending forces applied to the rotator’s clamps. For pole mounting, the product of multiplying the [Antenna Wind Load Area (in m2)] by the [Height of the Antenna Mast (in m)] must be less than 0.45 (G-800DXA/- 1000DXA) or 0.8 (G-2800DXA). See below Table and Figure.
[Antenna Wind Load Area] x [Height of Antenna Mast] = 0.45 (G-8000)(A/-1000DXA) 0.8 (G-2800DXA)
Refer to the antenna manufacturer’s specification sheet for determining the weight and the surface area of the proposed an­tenna.
Example: For a 14 MHz 3-element Yagi of Surface area of 0.7 m2 (see Table), the above specifications for pole mounting will be met if the antenna is mounted on a mast not longer than 0.3 m (0.7 1n2 x 0.3 m = 9,21 < **0.27 [0.45 x 40 % safety margin]: G-800DXA/-1000DXA), or 0.6 m (0.7 m2 x 0.6 m = 0.4Z < 0.48 [0.8 x 40 % safety mar­gin]: G-2800DXA).
Advice:** We recommend that your antennas/mast should not exceed 60 % of the maximum rating, to ensure a safety margin.

Tower-Mounted Antennas

In the preferred tower-mounting configuration, the antenna Wind Loading Area must be less than 2 m 2 (G-800DXA), 2.2 m 2 (G-1000DXA) or 3 m 2 (G-2800DXA), and the “K” factor (see below) must not exceed 180 (G-800DXA), 230 (G­1000DXA) or 950 (G-2800DXA), where K = [Antenna Turning Radius (m)] x [Antenna + Mast Weight (kg)].

Refer to the antenna manufacturer’s specification sheet for determining the turning rants and weight of the antenna. Example: In this example, mount the following antennas stacked on a 6 kg mass.

• 14/21/28 MHz 5-element Yagi of Turning Radius 5.6 in, Weight of 26 kg, and Surface area 0.7 m2
• 18 MHz 3-element Yagi of Turning Radius 5.0 m, Weight of 14 kg, and Surface area 0.7 m2
• 50 MHz 5-element Yagi of Turning Radius 2.6 m, Weight of 5 kg, and Surface area 0.3 m2

Note: In such “Christmas Tree” installations, compute the mast weight separately for each antenna, using the relative heights of the antennas to apportion the mast weight.
The antenna system K factor, then, is the sum of the three antenna K factors:

The Wind Loading Area (1.7 m2) is within the specifications for the G-800DXA, G-1000DXA, and G-2800DXA, but the net K factor (255) can only be met by the G-2800DXA. Therefore, the above antenna system should only be mounted us­ing a G-2800DXA.
Advice: We recommend that your antennas/mast should not exceed 60 % of the maximum rating, to ensure a safe mar­gin.

Mast Bearing GS-065 (option)

Note: Installation of a Thrust Bear-ing such as the GS-065 does not allow the elimination of the mast weight from the K-factor calculations above.

Control Cable Installation

Before installing the rotator, mast, and antenna, prepare the rotator control cable and test rotator system performance on the ground. Potential alignment, cabling, or other problems can quickly be resolved on the ground; once a rotator is mounted, however, troubleshooting may require that the tower be climbed and/or the rotator be removed and lowered to the ground!

Control Cable Preparation (G-800DXA/-1000DXA)
In the G-800DXA and G-1000DXA models, the user must supply and prepare the control cable, per the simple instructions below.

The control cable to be used should have five stranded conductors of at least 0.5 mm (#20 AWG) diameter if the cable is shorter than 40 m in length (125’); if the cable is longer than 40 m, use conductors with a diameter of 0.75 mm (#18 AWG) or larger.

1. Disassemble the supplied round plug: slide off the rubber boot, remove the setscrew from the shell using a small screwdriver, then unscrew the shell from the plug. Save the setscrew in a safe place until step 10, so you don lose it.

2. Slide the rubber boot, the round shell, and the connector assembly components onto the “rotator” end of the cable as illustrated. Leave enough cable protruding to allow easily dressing the end of the cable.

3. Using special care to avoid nicking the insulation of the individual wires, strip back 20 mm (about 25/32”) of the outer jacket from both ends of the cable.
   Now strip 4 mm (about 5/32”) of insulation from each wire, being careful not to nick the conductors.

4. Solder the wires to the (rotator end) round plug pins.
   Note the color of the wire and the number associated with each pin for reference later. Pin 6 and 7 of the round connector are not used! Confirm that all solder joints are firm and cleanly made, as this part of the cable will be difficult to access once the rotator is installed on top of the tower. Do not slide the shell onto the connector at this time.

5. Crimp the supplied pin contacts onto the wires on the opposite (controller) end of the cable, per the illustration on the next page.

6. Referring to your notes of the wire color at each pin of the round (rotator end) connector, insert the pins into the supplied rectangular plug at the opposite (controller) end of the cable. Be sure that each wire from the round connector is routed to the correspond- ing pin number in the rectangular connector (i.e. 1 to 1, 2 to 2, etc.).

7. Temporarily connect the round plug to the rotator and the rectangular plug to the controller. Make sure that the POWER switch on the controller is set to “OFF”, then plug the controller’s AC cable into your station’s AC outlet.

8. Set the controller’s POWER switch to “ON”. The pilot lamps on the controller should become illuminated, and the meter needle on the controller may rotate so as to align itself with the current position of the rotator (remember the two units have not been aligned with each other).

9. Press the LEFT (rotation) side of the seesaw switch, and confirm that the rotator (when viewed from the top) and the controller’s needle turn counter-clockwise together.  Stop rotation, then press the RIGHT (rotation) side of the seesaw switch, and confirm that the rotator and indicator needle-turn clockwise. If rotation does not occur as indicated, turn the POWER switch “OFF”, and re-check your cable connections.

10. If the rotator and controller are working as described, replace the plug shells, setscrew, and rubber boot (removed in step 1).

Mounting the Rotator and Antenna

INDOOR PERFORMANCE CHECK AND ALIGNMENT

1. Temporarily connect the control cable between the rotator unit and the controller.

2. Turn the SPEED control fully counter-clockwise, and set the SELECT SWITCH on the rear panel to the right (ADJ. MODE)

3. Check to be sure that the POWER switch on the con­troller is set to “OFF”, then plug the controller’s AC cable into your station’s AC outlet.

4. Set the controller’s POWER switch to “ON”. Verify that the controller’s pilot lights have become illumi­

5. Press the LEFT (rotation) side of the seesaw switch, and continue to hold it until the rotator reaches the counter-clockwise position where it automatically stops (“Left” represents counter-clockwise rotation when the rotator is viewed from the top).

6. When the rotator has reached the left “stop” posi­tion, release the LEFT switch, and check to see if the controller’s indicator needle is pointing to 180° (S: South).
   If the indicator needle is out of alignment, grasp the edge of the bezel around the bearing window, turn it 10° counter-clockwise, and pull it off. They grasp the needle at its center and pull it straight off, replace the needle to 180° (straight down), and replace the bezel.

7. Just above the round connector jack on the rotator unit, you will observe two raised calibration marks (one each on the “rotating” bell and “fixed” base of the rotator). These two marks should be directly aligned with each other. If not, place a small piece of masking tape on the rotating bell and the fixed base of the rotator unit, and make a calibration mark will be used to verify the amount of rotation in the next step.

8. Press the RIGHT (rotation) side of the seesaw switch, and continue rotating to the right until the calibration marks (from step 7) are again precisely aligned. Now check the indicator needle, which should also have rotated fully 360° so as to be pointing exactly to 180°.
   If the indicator needle is not pointing exactly to 180°, go to the rear panel of the controller, and use a small screwdriver to adjust the FULL-SCALE ADJ po­tentiometer (see the drawing to the right) so that the indicator needle points exactly to 180°.

9. Press the RIGHT switch again, and continue rotation to the right. You should observe the OVERLAP LED becoming illuminated as rotation passes the 180° If the OVERLAP LED does not light up at the 180° position, the OVERLAP LED ADJ potentiometer (on the rear panel of the controller) may be used to align the illumination threshold to the 180° point.

10. Check to verify that rotation automatically stops at approximately 270° (West; representing a total rota­tion range of 450° from the original starting point).

11. Press the LEFT and RIGHT (rotation) switches a few more times, verifying that rotation appears to be normal. If so, press the LEFT or RIGHT (rotation) switch to set the rotator to 270° (West).

12. Set the PRESET control to 180° (fully counter­clockwise), and press the START The rotator should rotate counter-clockwise, and stop exactly at 180°.
    If not, go to the rear panel of the controller, and use a small screwdriver to adjust the PRESET ADJ A potentiometer so that the rotator stops at exactly 180°.

13. Set the PRESET control to 270° (fully clockwise), and press the PRESET The rotator should ro­tate clockwise, and stop at exactly 450° (270°; West).
    If not, go to the rear panel of the controller, use a small screwdriver to adjust the PRESET ADJ B po­tentiometer so that the rotator stops at exactly 450°.

14. Repeat steps 12 and 13 several times until the indica­tor responds reliably to presetting small angles when the rotator is near both ends of its range.

15. Set the SELECT SWITCH on the rear panel to the left (OPERATION MODE) position, and turn the POWER switch –OF’.

16. This completes the ground-based testing of the rotator and controller.

Controller Rear Panel

Installing the Dial Heading Sheet
A clear plastic round dial heading sheet is provided with the kit, which can be installed north at any position you desire. This is particularly useful when you need to have south at the top of the dial (or east or west) instead of north.
To install the heading scale:

• Turn on the POWER switch and press the seesaw switch to set the indicator needle to 180° (straight down), then turn off the POWER switch.
• Grasp the edge of the bezel around the bearing win-dow, turn it 10° counter-clockwise, and pull it off.
• Note the position of the needle, then grasp it at its center, and pull it straight off.
• Determine which compass direction you desire to be upmost, and install the compass heading label sheet against the azimuth scale, so that the small teeth in the edges of the sheet lock around the edge.
• Replace the needle and bezel in the same direction as they were before (see diagram below).

PRESET Knob Calibration
Perform this procedure only if it is not possible to align the PRESET knob tracking using the PRESET ADJ A and PRESET ADJ B potentiometers on the rear panel, as described in steps 12 ~ 14 on the previous page.

• Pull off the PRESET control knob.
• Set the potentiometer shaft to the fully counter-clockwise position, then turn it 30° clockwise.
• Using care not to disturb the PRESET potentiometer, push the knob back on the shaft so that the knob stopper is aligned with the counter-clockwise edge of the slot in the panel behind the knob, as shown in the drawing to the right.
• Repeat steps 12 and 13 on the previous page for the PRESET Dial Tracking Alignment.
  Do not forget to set the SELECT SWITCH on the rear panel to the left (OPERATION MODE) position after alignment.

Installation of the G-800DXA/G-1000DXA Rotator and Antenna on Tower

Important!! Before mounting the mast to the rotator, a single hole must be drilled through the bottom of the mast to accommodate an anti-twist support bolt used in the base support clamp halves.

1. Drill a 9 mm diameter hole through both walls of the mast, centered 50 mm from the mast bottom (see Figure 1). Ensure the drill is maintained perpendicular and centered when making the holes, to ensure proper alignment of the holes in the mast with those in the base support clamp.

2. Attach the rotator to the tower’s rotator mounting plate, using the supplied M8 x 16 bolts and spring washers. It is recommended that the tips of the bolts be lightly dipped  in lubricating grease, to ease disassembly in the future (see Figure 2).

3. If a thrust bearing (such as the optional Yaesu model GS-065) is to be utilized, mount it on the top of the tower (see Figure 3) using the supplied hardware.

4. Partly tighten the mast clamp À to the rotator housing using the supplied M8 x 25 bolts Á spring washers and flat washers (see Figure 5).

5. Using a “gin pole” or other raising fixture, insert the antenna mast through the bearing from above, and set the mast in the rotator’s mast clamps, then partly tighten the mast clamps using the supplied M8 x 70 bolts  and spring washer.
   Advice: One side of the clamp has ridges on either side of the bolt holes; the bolts should be in- serted from this side, so the ridges hold the bolt head from turning.

6. Pass the supplied M8 x 95 screw Ä through the mast clamps and through the mast, then partly tighten it us- ing the supplied square nut Å.

7. Partly tighten the thrust bearing’s mast bolts, so as to center the mast in the thrust bearing. When you are satisfied that the mast is centered, tighten the thrust bearing’s mast bolts to secure the mast in place.

8. Now tighten all the nuts of the mast clamp except for the square nut holding the M8 x 95 bolt through the mast clamps and mast. Leave the square nut only lightly secured at this time.
   Caution: Do not over-tighten the nuts on the mast clamps. They should be tightened until the spring washer becomes flat, then tightened further by 1/2 to one turn maximum.

9. Install the rotator control cable’s round plug into the jack on the side of the rotator’s base, and tighten the connector ring to secure the connector. Slide the rubber boot over the connector; while putting a slight amount of inward pressure on the rubber boot, use electrical tape to secure the back end of the rubber boot to the cable. This slight inward pressure on the rubber boot will enhance the weatherproofing of the installation. Secure the control cable to the tower in several places, using electrical tape and/or UV-resistant cable ties.

10. Get a ground crew member to set the controller to 180° (South), which corresponds to 180° of rotation clockwise from the left “stop” point. During rotation, watch the  M8 x 95 bolt to be sure it does not bind between the mast and the mast clamps. If binding is observed, stop rotation and make slight adjustments to the thrust bearing and/or mast clamps, so as to eliminate the binding. If the M8 x 95 bolt is not binding, you can go ahead and tighten the square nut securely.

11. Provide sufficient slack in the coaxial cable such that the antenna can rotate over its full 450° range without putting any tension on the coax (see Figure 8). Secure the coax to the tower, using electrical tape and/or UV-resistant cable ties.

12. Installation is now complete. If you have scratched through the melamine coating of the rotator during installation, you may wish to apply several coats of clear acrylic spray to help protect the bare metal from corrosion. After installation is complete, test the system by operating the rotator through the entire range of its rotation. It is helpful to do so with the help of an observer, so that rotation can be stopped if some obstruction, binding, or tension on the coaxial cable’s turning loop should be encountered during the performance test.

Installation Note
If using a roof tower with a long mast between the top of the tower and the antenna, the use of a “Guy Bearing” is highly recommended. The Yaesu GS- 050 and GS-065  include guying “ears” which allow attachment of guy cables. As installing a guying system may cause the center lines of the guy bearing and the rotator to become misaligned,  be certain to check the roof tower attachment and guy cable alignment to ensure that the mast is straight.
