Bought one several years ago from Kevin @ the Repeater-Builder booth in Dayton. Works very well (~0.13 µV for 12 dB SINAD on the MVP it's in), but now I need another one. Got another one, Kevin? If not, does anyone else?
BTW, I did the antenna-load sensitivity substitution test last night on 2 MVPs, one with & one without the preamp. The MVP with no preamp showed ~5 dB SINAD degradation between the antenna & load. With that much noise coming down the antenna, reducing the noise figure of the RX doesn't help much, maybe a dB or two. But once you throw in the duplexer loss, which in this case is 2.1 dB, the antenna noise is reduced to only 3 dB over the load. Now the preamp improves actual sensitivity by 3 dB, which is just enough to make it worthwhile to use IMO. In addition, this will be for a portapeater that will be deployed in a rural area so the antenna noise will probably be lower. Bob NO6B
