Well, as Rich (KD8KBO) would say." Them Boys are up to No Good Again". And he would be right.
A while back a few of the3 Woodchucks, Larry (N8OWS), Chuck (K8CVM) and Jim (W8MIJ) started investigating the idea of using an old Satellite Antenna as a VHF/UHF Antenna.
“A slot antenna is a narrow rectangular opening in a large conductive surface, such as a TV satellite dish. Slot antennas are familiar in the commercial radio world, but not to hams. They’re common in TV broadcasting, the skin of aircraft and in radar, microwave and cell phone applications. This disguised TV dish slot is equal to a J-pole.Efficient 2-meter Disguise Antenna Made From a TV Satellite Dish This horizontal “slot” antenna, cut into the reflector of a TV dish, is both the master of disguise and high in performance.

So, the boys tried it. The dish was acquired, the slot was cut and is was wired-up.
We tested it at Chuck’s (K8CVM) House by attaching it to the mast on the “Ham Van”.
Initial test showed a high SWR (@4:1) using the recommended feedline attachment points, 3 to 6 inches from an end. We found that 1 ½ in. worked for us giving us the lowest SWR .
The antenna was tested at a height of @15 ft and several local Repeaters were contacted for signal reports, Rich (KD8KBO) helped us with this task.
Chuck (K8CVM) ran the Woodchuck 2m FM net on 10-23-2019 from the “Ham-Van” using the Slot Antenna.
