[TowerTalk] Triplexer

[john at kk9a.com]

A single op can only transmit one signal at a time so the combined wattage
would only be an issue for multi-ops. This is a good question, can the
triplexer could handle three H.P. stations on simultaneously.

Many contest stations have multiple tribanders pointing in different
directions. For maximum flexibility you may need a triplexer on each beam?

&&&  No, what I meant was say 3 amps, all running 1.5 kw RTTY..
simultaneously
= 4.5 kw average power.   Per Eimac, that would be the same as a 3 tone
signal,
with each tone having an average power of 1.5 kw.
(Number of tones) squared,  X 1.5 kw  =    13.5 kw pep out.
13.5 kw pep out =  825V rms = 1166 V peak.

&&&  4.5 kw average, would be max worse case.  Still, on CW,  with all
3 on TX, it would still be aprx 2 – 2.25 kw average.  So it may still work.

&&&  The other issue would be the tribander would be pointed in 1 direction,
so all  3 bands would also be in one direction, which may not be what you
want.
But folks with rotating towers face the same dilemma.
