In most casual situations (not a a major comm site with other adjacent repeaters and a broadcast station or two nearby) pretty much any type of decent preamplifier works very well. I like the ARR Preamplifiers because they work well and are often found fairly cheap on Ebay. The old GLB (now owned by someone else) are very good layouts for busy locations. Other people have told you about Angle Linear and I'll throw in both Telewave and Hamtronics as a source. Everyone wants to dance and sing about GasFet and Phempt device preamplifiers but there is more than a valid case around to obtain and use bipolar device versions (preamps) ... And you'll hear lots of opinions about how much gain to use/buy. Depending on whose camp you're in the reply might be that x-amount is enough to not much all the way to the other extreme where as much as you can. And the amount of gain you end up with should again depend on you specific situation. I tend to lean toward the as much as you can side because I like to use mostly hand held on low power portable radios. I can work my 22 mile distant ham repeater from inside my house with less than 1/4 watt of power. So the real answer to your question might be... where ya gonna put the repeater? s.
