I use Gigavac GH-1 vacuum relays for detuning my TX antennas when receiving. The contact closure/release time is 6 msec. You have to dial in enough QSK delay in your radio so that you don't hot-switch the relays.

For you folks that have to de-tune your TX ant, so your dedicated RX ant works correctly,
if you also operate qsk, how do you do it ? Are you using a sped up vac relay to de-tune
the TX ant ? I don’t see any other way to accomplish that task. Or do you use vox cw ?
