For portable operation the switched ARR pre-amps, as have been mentioned, are a good option. But don't take them out in the rain!

For weather-proof mast-mounted pre-amps, I've had very good luck with the Mini-2 and Mini-70 GaAsFET pre-amps from SHF-Elektronik in Germany (http://www.shf-elektronik.de/en/). At current exchange rates, these are roughly the same price as the ARR, and considerably cheaper than some other mast-mount alternatives. The IC-9100 powers them through the coax without the need for any other supply.

I have no affiliation with the company, but they've been working flawlessly for me for a couple of years now at my home station.--

Subject: [amsat-bb] AMSAT Broadband Preamp

I started working some of the LEO SSB satellites again recently and came
across a broadband preamp that is sold by AMSAT. Here is the link:

Has anyone here used this before?  Perhaps this would help me 'hear' a
little better with my Arrow antenna, and I could use it for V/U and U/V
modes. For those of you that operate with an Arrow, do you use this preamp
or some other preamp?  It appears there are other preamps out there that
are more expensive, but require one per band (V or U).  This one will cover
both - seems like a good option, just wanted to get your thoughts.

Thanks!  Dave N2TEB
