Jay, I was thinking of suggesting the addition of UVSJ as an brief entry in the Reviews threads, as well as to the acronym list...
Anyway, UVSJs are similar to splitters in that they're both commodity products. Pico Macom is the gold standard, of course, but the company halted production some time ago, so "real" P-Ms have been hard to come by for quite a while now. I've seen some chatter recently about a production re-start and that they'll soon become more widely available, though.
Pico Macom claims insertion loss of 0.5
dB on its UVSJ. Tru Spec, Holland and other brands run about 0.7
dB. The difference is, basically, nothing. Compare either to the 3.5-
dB hit from the Winegard
CC-7870 VHF-UHF separator/combiner; that's no better than how a splitter in reverse would perform! Channel Master claims an 0.5
dB loss on its 0549 combiner, but it costs $9 instead of $4.
