Dual antenna combiner systems tend to 
be the better preformers.

Yes, but remember his freqencies are 
close spaced, within 1MHz of each 
other.

One often has to play the cards (freqs) 
dealt.

Most antenna combiner mfgrs should give 
you a quote and basic engineering. Decibel 
and Telewave are other options.

One can do better by shopping Ebay.

Playing the game is indeed expensive at

Any time you can keep the transmitter(s) 
out of the receiver scheme, the better 
off you are out of the starting gate.
