My understanding is that it’s still one physical radio, just broadcasting on 
two different frequencies.  So, both pairs of antennas are transmitting at the 
same time, and both pairs of  antennas are receiving at the same time.  Which, 
to my mind, means you’d want to treat them like any other collocated synced 
radios; no overlap, but little or no guard band required.

Subject: [Telrad] Split Mode 2f

 

I've been meaning to bring this up for awhile:

 

They created split mode 2f for situations where you want two sector antennas on 
one Compact, but the two are not placed back to back.  How far apart do the two 
frequencies need to be?

 

I had the two channels adjacent, but we had UE's dropping off.  Then I spread 
them out so there's a large guard band between them and we stopped having the 
issue.  Does anyone know how close they can safely be?
