[TowerTalk] Some thoughts on coax leakage

[Chris R. Burger]

NJ2L concludes a good discussion of coax leakage with:

I submit that this factor is only important in co-frequency 
situations, where antenna coupling would be much more significant 
anyway.  In any other situation (e.g. adjacent bands), the bandpass 
filtering in the receive chain would serve to reject those signals.

Or am I mistaken?
