I build my own low-loss RF cable assemblies of minimal length and skip an amp altogether.
Crimping those SMA/TNC/FME connectors is half the fun right?! I've become fond of this online store: http://www.wpsantennas.com over the last couple of years with their selection and product variety. I'm a fan of the Laird antennas, although I haven't poured over the details as much as a couple of you have. I do enjoy learning as much as I can along the way though. The Mobile Internet handbook by Technomadia and their website are also good places to do some light reading if learning is of interest to anyone.
