Antenna switches

Manually switched in the shack, or electrically controlled at the top of the mast. There are many antenna switches.

At the latest from the second antenna on - you need a coax switch in the shack. Of course, better equipped radios have several antenna connectors, but often it is important to be able to switch one antenna to different devices, for example a separate SDR receiver. Here coax switches provide valuable help, for example, they allow a quick comparison between different antennas or devices. There are manual coax switches in many different configurations. Decisive factors are the number and types of connections, and up to what maximum frequency and power the switch can be used.

Another class are external antenna switches near the antenna. They are used when only a single cable is to be laid from the mast to the station, but several antennas are still used. These switches are weatherproof and usually have a remote control unit at the station. Some switches are universally designed for many different control signals. Selection criteria are again the number and type of coax connections and the maximum possible frequency and power.
