I would like to use separate antennas for transmit and receive. Most transceivers have a single antenna connector. A high speed external relay would be required. Does anyone have experience with this? Recommend a relay and source? Relay control circuit? There does not appear to be anything in QST archives. VE6MU |

A vacuum relay is pricey, but the method of choice when running high power.
