Below left: My present day antenna farm consists of a Rohn
FK2558 foldover tower using a 4-point guying system. Atop the tower is a Hy-Gain TH3MKII
tribander that I have had since 1966. It has been rebuilt 3 times over 40 years and still
delivers excellent performance. It is rotated by a Hy-Gain Ham IV rotator. Also mounted on
the tower is a Diamond X-510 vhf/uhf vertical and full wave loops for 40 and 80 meters fed with Balun Designs 2112 (2:1) transformers and a inverted-L for 160 meters fed thru a motorized base matching
capacitor. (Heathkit SA-2550)
Below right: 160 meter control enclosure with Balun Designs 1:1 Chole Balun, Hathkit SA-2550 motorized 500pf capacitor, Alpha-Delta TT3G50 Surge Protector and copper ground buss. On the outside right of the enclosure is a Array Solutions bleeder inductor for the 160 meter inverted-L . The Heathkit SA-2550 motorized matching capacitor
for the 160 meter inverted-L antenna is controlled from the shack. With this unit it
is possible to match the antenna any place in the 160 meter band with a flat 1:1 SWR
Currently I have 40 resonate (130') radials bonded to the round aluminum plate
which in turn is connected to the 2" copper pipe which is sunk 8 feet in the ground.
