Relays are available in either a Wired type or an Wireless type. The Wired versions require DC power to be brought to the relay. The Wireless versions can decouple DC power injected into your coax cable through the use of a Power Coupler. All relays are weatherproofed for mounting outside. With the Wireless Relays you can inject the DC power required by the relay in the shack and have the relay operate at a remote location. These Wireless relays separate the RF signal from the DC voltage off the same coax line. Wireless relays are therefore ideal for switching antennas at tower tops or locations far from the station where the required DC power is unavailable. Two and three position require 0 & +12 vdc and -12vdc & 0 & +12vdc, respectively.
