[amsat-bb] Mast-mounted preamp recommendation?

All,

Does anyone have any recommendations on high quality mast-mounted preamps for UHF? We're using the Icom AG-35 and not happy with the noise figure. We're going to try an adjustment described here http://www.eham.net/reviews/detail/6116.

We are looking at the amps from ARR and SSB. Any other recommendations?
