​Hello all, Awhile back there was some discussion about switching Beverages. When I was back in Illinois, I had three bi-directional Beverages and I assembled my own circuitry for switching between antennas and directions. Being an industrial electrician, for me the project was rather straight-forward.
I used an 8" square Carlon® PVC outdoor-type weather-proof junction box and in this box, I fashioned up a "bottom plate" on which I mounted two "DIN rails" - for holding the relay sockets, for the 6 "ice cube" relays. I used 120VAC relays and each relay, when not being energized, grounded each center conductor of the six 75-ohm coax cables through a 75-ohm, 5-watt Xicon (286-75-RC) resistor. On the bottom of the enclosure I installed seven RCA-type phono jacks - six for the 75-ohm coax cables from the Beverage transformers and the last one being the "output" of the relay that was being selected. I made up a control box, using a 2-deck rotary switch; one deck being for the 120VAC that energized the ice cube relays and the other deck being used to power low-voltage indicator lights that gave a visual indication of which of the Beverages had been selected. I used a 120VAC step-dowm transformer and a resistor of the proper size, to supply the proper voltage for the indicator lights. That was how I did it. A BIG thanks to Gary, KD9SV, for all of the helpful hints and low-band education that he has supplied me with... 73 de Brad, N9EN Bluff City, Tennessee "in the hills"... _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
