PCB
Transformers winding - ⚠ very important thing!
- for 50 Ohm coax feed line: 2 turns on primary (coax) and 6 turns on secondary side
- for 75 Ohm coax feed line: 2 turns on primary (coax) and 5 turns on secondary side
Transformer should have 5 + 1 turns. So you wind 5 turns and 1 more as a tap.
CMCC construction
- common-mode current choke construction
- wind 4 turns on one side then cross to another side of the cores and wind rest turns.
Terminator Box
This box contains of Load resistors for the antenna and protections.

FAQ
- GND screw on feeder box is insulated from Coax shield. This isolation prevents introducing unwanted signals and noise into the antenna system. Grounds are insulated by Common-Mode filter.
- Connect the ground terminal screws only to earth ground using at least one (copper/army GND rods with screw) ground rod. Use as large diameter ground rod as possible.
- A good ground system improves performance (lower noise) and enhances lightning survivability.
- Copper wire is recommended. All depends on your WTH - ice, snow, animals etc. All this can damage antenna wire. Using (army) wire with steel wires is recommended. You can also add more supports and lighten the wire.
- With advantage you can use wire antenna insulator pack which you can find at our web category PARTS & ACCESSORIES.
- When the antenna is mounted on place, you can measure SWR. With VNA or antenna analyser. SWR must be lower than 1:2 for 75 Ohm output and 1:1.7 for 50 Ohm version.
- You can change terminator resistor value to obtain SWR as flat as possible.
- Due to storms, lightning and animals we recommend to check SWR of the antenna time to time. If there is any problem with high SWR, please bring the feeder and terminator boxes close to each other and connect it with three short wires, measure SWR again.
- This is low noise antenna. When you try it first time you can have feeling that there is something wrong. Beverage antenna has lower gain compare to the TX one - signal can be weaker, but final result Signal-to-Noise should be better. This is advantage of this antenna.
- Beverage antennas should be installed more than a wavelength from other large metallic structures, such as vertical antennas, towers, power lines, electric fence wires etc. Antenna units can be mounted on trees, wooden pole or fiberglass rods. Do not use metal pipes. Never mount this unit with the connectors facing up.
