Ham Antenna Relays at Cristal Lin blog

Ham Antenna Relays. But, not as much of a challenge, and. Tx/rx antenna selection is being done automatically (split antenna operation) and controlled by the ptt of any of the rigs connected. Antenna tuners use fairly standard 250 v relays, so this would be a good place to start. The schematic shown is for 3 antennas but it's extendable. The circuit of the shack switch, allows for 4 separate rigs to be selected, and two antennas, one for rx and one for tx. Many projects on the web have done this but the relays have silver contacts. If you get a multi level version, you could switch the antennas with one, and led's with the other. This post has some nice photos of its relays. It achieves a phenomenal port isolation of 82 db on 40 meters and 69 db on 10. The ea4tx as2x2 antenna switch is designed to exchange two antennas between two radios. It allows selecting one of 6 antennas for each band without affecting other receivers.
