Steve,
The RX antenna input is protected by a Carrier Operated Relay. Other
than that, there is no relay to disconnect the RX input.
If your TX antenna is sufficiently separated from the RX antenna, there
is no problem.
How much is 'significant' is often a question, and the answer depends on
your particular antenna installation.
If you hear the COR relay operating, yours is not providing sufficient
isolation and you should look into an external device (likely a relay
will do) to disconnect the RX antenna during transmit.

Am I correct in assuming that the Rec Ant input is disconnected from the main
receiver input upon transmit by way of a relay? If so, can I further assume
that connecting a beverage, or other receive antenna, to the Receive Ant input
will cause no harm to the main receiver upon transmit? In other words, is a
relay enough protection?
I ask because I would like to rule out needing an external protection device
when using a beverage antenna. I run full legal power.
