Driven Element
Driven Element
Under Construction
The reflector and driven elements are built some what the same. I will cover the driven element first. I used 1/8” plastic to build a mount for the SO-239 and secure it with #6 screws and nuts. 2 of the #6 screws are 1/2” for the top and bottom of the SO-239 and a #6 by 1” on the side, this will be used to connect one side of the driven loop. Use #12 copper wire (I leave the insulation on) for both elements. Each side of the driven element will be 20 1/2”. Each side of the reflector is 21 21/32”. Feed through the support and then put the 90 deg bends in. For the reflector you will make a loop and solder the ends together. After the assembly of this part of the antenna I hung it from the false overhead with string, added the first director and use my antenna analyzer to check the SWR. It tuned in at 145.9 with 1:1.2 and at 144.2 it was 1:1.4. I hope this will come down once it goes up on the tower.
