Short answer - on UHF the cavity duplexer passed VHF (paging - FM broadcast very well - went from a dual band antenna to a single band db420 really helped - using wacom bpbr duplexer with arr gasfet then 1 bp cavity then antenna. Colocated with some VHF paging, 850 SMR and 450 LTR. Going to a single band antenna made the biggest difference. Steve NU5D
