Item 4 is what I am talking about. If your radios have very good

antenna has minimized any of the coupling I mentioned, then they may be
able to listen through the "noise" from the other transmitter.

2. The normal isolation between vertical polarity and horizontal

Depending on various factors, you should see at least 15db of
attenuation between polarizations on a dual-pol antenna. Theoretically,
you should see 20db. In any case, 15db is enough attenuation even on the
same channel to operate two links reliably.
