WiMo 17754.0604 6m-4m Dual band Moxon Antenna Instructions
Thank you for choosing E Antenna.
All our products are manufactured and developed with the best materials on the
market, to offer the best qualities and guarantees to our customers.
The Yagi type MOXON antennas were developed by Leslie A. Moxon, to be used in communications in HF during the 2nd half of the 20th century, quite successfully. Its cost, profit and ease of construction make it an option very convenient. As it is a specific antenna according to the bands in which we want to operate. The address of the maximum Gain is obtained in the opposite direction to the reflector and perpendicular to the radiating element. According to the position with respect to ground, horizontal or vertical, will be its polarization. It is very important that this coincides with the polarization used in the antenna of the equipment to which you connect with this antenna. Like any antenna manufactured by EAntenna, we do not include a connector, to have the minimum losses. We include terminals to solder directly, although we offer as an option balun or ferrites EMI / RFI.
We detail the materials used, for their best use and assembly. All the fittings are made of stainless steel and the Aluminum is made of T6061 or T6063 alloy, known as Aeronautical Aluminium, which offers the best conditions to withstand the most extreme climates, the force of the wind and the best conductivity. The plastics used, is Polyamide or Polypropylene, which offer the best hardness and durability for the passage of time. We offer guarantee in the operation, and guarantee in the ironworks, delivering the kit of hardware some extra pieces, for possible losses or forced breakages.
In the following pages we detail the exploded view with its graphics.

The measures of the previous page are expressed in external dimensions, ie, measuring from each end of the tube. Once the horizontal elements are assembled correctly, proceed to form a rectangle with the measures provided below.
Take into account the position of the ends according to page 6, to take account of the reflector and drivendo not reverse.
To set the reflector to boom, position the plastic clamps of 13mm (EAHYP013)
in positions where it belongs, and fixed with screws
DIN 912 M6x40.
BOTH ELEMENTS
The fixing of the LOOP element, each element is using a Hose Clamp 8-16mm
(P0100022) the 13 to 10mm diameter.
**The final lenght is the presintonized. The lenght is from the end of the
13mm tube to the outside of the bend tube.

Assembly instruction
The assembly of elements, once selected all lengths, place in each half of Ø
13mm front, insert one by one, the tubes of 10mm diameter x 200mm (EA0120010)
in one of the 13mm tube. Once fixed and the first part of an item, enter the
next half and secure again screws DIN 7984 M4X10 and the M4 Insert rivet which
is detailed below. Note that the screw head has to be accommodated within the
bigger hole in element.
The fixing of the LOOP element, each element is using a Hose Clamp 8-16mm
(P0100022) the 13 to 10mm diameter.
Measures page 2 are expressed in external lenght , ie, measuring from each end of the tube. Once elements are assembled correctly , proceed to put each item on the plate to the boom , which would be the last step assembly . Attach plates to boom as specified below .
Once you have the elements assembled, and the boom, it’s time to mount the
plates to the boom and then the elements to the plate.
What we advise is to start with the plates to the boom, if you rise up the
antenna in one piece. If what you want is to raise the elements once the boom
is placed on the mast, we recommend putting the elements to the plates for
their best way of the “plate / element” assembly to the boom.
To place each plate to the boom, are fixed by screws DIN 912 M6X20 and DIN 9021 M6 washer. This plate must be very firm for positioning the element. The next step would be like the other elements, but considering that the screws use are DIN 912 M6X40 and DIN 985 M6 self-locking nuts once it is all assembled antenna.
MAST TO BOOM PLATE ASSEMBLY
The clamping plate BOOM / MAST (EA013018) 100X100X6mm consists of 8 holes; 4 thick for round U-bolts and 4 square U-bolts for securing the BOOM. The 4 holes are thicker function that make the greatest force on the mast by means of M8 round U-bolts. Round U-bolts M8 (A-0163), are secured by washer DIN 9021 M8 and nut DIN 934 M8 provided in the same bag, and fixed to the mast with clamp (23035.50). Detailed drawings for further illustration:

After several trials, we see that the balun aluminum makes it worse job than a
coaxial choke. For this, we recommend 5 turns of 8 cm and thus the RF return
will be minimal or absent. The below drawing advise you how to do the clash
below the boom to avoid interaction with the elements
Keep the splice as short as possible !
