Hi,
I've just received the comtech 13cm TX & RX boards along with the controller.
Can anyone advise what I should use for an aerial changeover relay?
Best regards

Hi Chris,
You can get SMA RF relays from ebay but they are not that cheap anymore... ~£25 for 12v operating ones, sometimes less for 28v versions.
An alternate option is to use a diplexer with one antenna for both Tx and Rx as long as they are on different frequencies - repeater use.
I have some diplexers available (they are quite big!) the only problem there is that you are fixed to certain frequencies.
