I tried a cheap TQ2SA SMD relais for RF switching. The circuit was using the 2 switches as one SPDT switch with the unused output connected to ground.
Find some pictures attached. For low power it should be possible to use the relais up to 70cm (ok, 30dB isolation only). On 2m and below it works with good results…
