[amsat-bb] Info needed "European 145 and 435 MHz Diplexer and Dual Band Filter (Model: DCI-145-435-DX-DB)"

[EC4TR Luis]

Thank you very much to all.
I see that the tips are unanimous regarding the use of a duplexer.
So far I was reluctant to use it not to introduce lost, since I use my
installation of VHF / UHF local contests
I have a "D original" duplexer that does not use and I've tested at work
with good results.
I will not be very difficult to climb the tower and place it just before
the preamp.
I'll tell you that this was me.
