Wideband Multicoupler Build Project

zz0468 that's a great idea. I swept a range 1 spectra filter once. It was like a brick wall at the edges.

Angle does make some medium wide band preamps, I have a 225-400MHz bipolar version, a high level tuned for 118-174MHz and another high level tuned for 400-500MHz.

Absolutely, without a doubt.

But I don't thinking he's marketing to the amateur market anymore. And he never did have a wide band model.

I've found that some of the ARR preamps have better IP3 performance than the Mini-Circuits amps do, and they have some wide band models with very low noise figures.

I was thinking in terms of 30-1000 or something like that, though... typical scanner coverage. I'm not aware of anything along those lines that he makes. His preamps usually cover a band, unless it's got a preselector in front of it, in which case the band is very very narrow! Things like the 225-400 were obviously designed for a specific market, and that was probably the requirement. If I recall right, those were originally for the shuttle program.

They're pretty decent, and probably quite adequate for a low level site. And broken radios are CHEAP!
