Moto T1504 UHF duplexer

[W2IBC]

I snagged a 4 can rack mount 1504 duplexer set.

!st thing that concerned me was where they was tuned at.. 508/511Mhz

Can I get these down to the 440 band? and how is it done? My Ideal specs would be .5db loss per can and of course 5mhz split.

easy to do, or barking up the wrong tree.

The 1504 will need a new set of cables made up to take it down to 440 mhz, the cans should be OK.

Mosy over to repeater-builder.com and look through the manuals for the T1504, looks like the loss will be 1.4 db on transmit, 1.4 db on receive (or 0.7 db per can)

AH HA. http://www.repeater-builder.com/motorola/t1500.html

I have to assume cable length determens the "band split" these things do.

insertion loss kinda makes me frown a bit.. but they will work for now I guess.
