Labgear LHG10T Professional High Gain 10 Bay T Band Aerial
Congratulations on the purchase of your LHG 10T aerial. The aerial is ideal for the reception of all available signals in weak and medium strength areas. The aerial design has been tuned to minimise reception of signals above 790MHz from Lte800 4G mobile phone transmitters which can interfere with digital TV channels.
Features include
- 15.0dBi Gain
- F type connector for secure and easy connection
- Fast simple assembly
- Encapsulated weather resistant electronic balun
Installation Instructions
For optimum results install the aerial using double screened CAl benchmarked digital coax cable (for the downlead) and screened coax outlets (not supplied). Use the F connector and weather boot supplied to connect the coax downlead (not supplied) to the F socket on the aerial.
-
Prepare the Coax Cable: Firstly fit the rubber weather boot provided, to the aerial end of the cable. Strip the end of the cable as shown in Fig. 1. Once you have stripped the cable, twist the braid and pull it back on itself, make sure that no braid is touching the copper core as this will cause a short on the cable and you will not get any signal.
-
Fitting the F connector: Now, simply twist on the ‘F’ connector supplied and trim the central conductor, as shown in Fig. 2.
For best results the aerial should be mounted on an outdoor aerial mast and pointed in the direction of the nearest transmitter making sure it is in a position where the transmitter signal will not be obstructed by nearby trees and buildings. If you are in any doubt about the direction in which the aerial should be pointing or the orientation of the aerial (horizontal for main transmitter, vertical for relay transmitter) check your neighbours’ aerials.
The aerial requires some assembly. If mounting on an existing mast check that the mast is in good condition and firmly fixed.
Aerial assembly -
The reflector bracket rotates through 90. When boxed it is usually in the horizontal position as it takes up less space. Before attaching the reflectors the bracket must be rotated into the vertical position as shown in Fig. 3 & 4. If you need to rotate the bracket push it towards the front of the aerial to unlock, then rotate clockwise through 90 using the arrow as a guide then pull the bracket back into it’s original position.
-
Rotate and lock the director elements into a vertical position. As shown in Fig. 5.
-
The main boom comes in two sections using the bracket supplied and the holes drilled in the boom sections join these two sections as shown in Fig. 5.
-
Connect dipole assembly to the main boom, insert the threaded bolt through the front hole on the underside of the main boom and the locating pin in the second hole on the underside of the main boom as shown in Fig. 6. Screw the wing nut supplied to the threaded bolt on the dipole to hold it firmly in position on the boom.
-
Slide the reflectors into the reflector bracket until the studs engage and lock into position as shown in Fig. 6 and Fig. 7. The reflectors can be fitted either way round.
-
Attach centre mount bracket in the position shown in Fig. 6. using the clips supplied.
Please note that when the reflector locating studs have clicked into place the reflector bracket is locked into position. If you are unable to push the reflectors in completely to locate the studs make sure the reflector bracket has been pushed all the way back (see Fig, 4). -
Fit the mast clamp attached to the aerial centre bracket onto the mast.
Then slide the centre bracket through the mast clamp to find the most evenly balanced position. Make sure the aerial is pointing in the direction of the nearest TV transmitter then tighten the wing nuts until the aerial is securely fixed into position, see Fig. 9.
You can also adjust the tilt angle of the aerial to make sure it is horizontal by adjusting the nuts shown in Fig. 8. Pointing the aerial slightly upwards can reduce noise pick-up from traffic etc. -
Connect the aerial downlead to the ‘F’ socket on the underside of the balun (be careful not to over tighten the F connector) see Fig. 9.
-
Slide the weather boot over the ‘F’ connector and socket to make a good seal – see Fig. 9.
-
Make sure that the downlead is routed as shown in Fig.10.
Use insulating tape, to secure the the coax downlead to the mast. -
Finally connect the aerial to your TV/set top box and check the picture.
Fine adjust the direction of the aerial to obtain the optimum signal reception.
Troubleshooting
No picture:
Check all connections from aerial to TV.
Poor picture:
- Check all connections from aerial to TV.
- Check aerial is properly aligned to the correct transmitter.
- If the aerial has been loft mounted try mounting outside.
- Make sure new digital coax cable has been used throughout the installation.
- Check the transmitter signal is not obstructed by nearby trees or buildings.
- If in a very weak signal area or for long cable runs, installing a masthead amplifier will improve the signal.
- If in a strong signal area the signal strength may need to be reduced by fitting an attenuator.
Caution
When mounting the assembled aerial, always observe safety precautions and use
the correct equipment.
Unless you are competent in the use of ladders and other access equipment, do
not work outdoors at roof height.
If in any doubt, refer to a qualified aerial installer.
