Duplexer Question



Hi,
This question relates to commonly available tri-band duplexers
(VHF/UHF/L-Band). 
Did anyone ever test some of those in a network analyser to
see the frequency response at the L-Band ?
The reason for asking this is that I would like to use a such a duplexer
with the L-Band port for a GPS signal (~1600 MHz). All the catalogs
I went over specifiy the ports as LPF/BPF/HPF, but after speaking to one
manufacture (Comet) they claim that all ports are BPF.
Any comments ?
Thank, Assi
