[amsat-bb] Masthead RF preamp suggestions?

[Burns Fisher]

I'll add for receive-only, check out the preamps that Airspy.us sells.
They have a broadband one (with no filtering) and also some band-specific
preamps.  The nice thing is that they can be powered by phantom power on
the coax, which can be supplied by a funcube dongle, and Airspy, or and
RTL-SDR.

As many have said, it all depends on the application!
