2×6 Antenna Switch Relay Board

This well engineered antenna switch board build with 2oz copper traces provides greater than -61dB port to port isolation, makes it impossible to put both radios on the same antenna port, minimizes reflective coupling. A DIY option not found anywhere else.

I provide the option to have unused antennas either open, shorted to ground, or terminated to 50 Ohms. Terminating to 50 Ohms will minimize reflections on the feed lines on unselected ports keeps the interaction from those antennas at a minimum in the switch. It is also sufficient to remove static build up.

2oz copper is used on the PCB which can allow 2800W key-down into 50 Ohms the trace heating will be limited to an acceptable 10°C. This also supports 1500W+ at below VSWR of 3. Trace spacing prevents high voltage arc-over as well.

The boards are designed with high RF integrity in mind to provide a hard to find DIY component for you to design around. Roll your own Raspberry Pi or Microcontroller based decoder and controller, or use the options I provide.
