[TenTec] Orion RX antenna input

I plan to use my Orion more efficient with both
receivers on different antennas.

One question comes up.

How much RF can the extra RX antenna input handle?
Can I damage something if I have to much RF on it?

I have antennas that are very close, a few meters.
When I run kW on one antenna there will be a lot
of RF into the other antenna, probably several Watts,
and that power will go straight into the input circuits
of the receiver connected to "RX ANT", or?

I have looked at the circuit diagram and see no protection,
there are a lot of relays, but I assume they don't switch
between TX and RX, or? "ANT 1" and "ANT 2" have diodes
muting the signal in TX mode, bot not "RX ANT"

I don't like to put a safety circuit on RX ANT input if it
isn't necessary. There are nothing in the manual of this
either.

Anyone done this succesfully?
or more important, Has anybody done this and burnt something?
