Hi Gary, I would use something like a DOW-KEY Transmit-receive relay. Connect the receive only antenna to the receive side and the transmit antenna to the transmit side. The antenna connection on the Dow-Key to the output of the Flex-3000. Use the TX-OUT to key the DOW-Key Relay. My personal choice would be one like: http://www.ebay.com/itm/Dow-Key-Relay-12-VDC-Coil-TR-Extra-Contacts-Nice-/22 0875136188?pt=LH_DefaultDomain_0&hash=item336d2f1cbc
I hope this helps.

To all, I have a Flex 3000, and I want to connect a receive only antenna to the radio. Is there some foolproof way to connect the receive only antenna such that I do not accidentally transmit to it? I know that I can connect the two antennas to different ports on my manual tuner, but I am concerned that sooner or later I will forget to move the selector switch from listen to transmit and fry the receive antenna.
