Hello folks,

I recently set up a  receiving antenna, and I found that in a SO2R scenario
I have fairly high RF levels at its feedline's receiver end when
transmitting with second radio on other band.

I would like to hear from you guys suggestions about how to prevent the RX
from being damaged.

I am building a RX antenna box, in which I will have a relay sequencer (, 3 position RX
antena relay and a norton preamp.
