[amsat-bb] Battery-powered UHF Preamp suitable for Arrow or Elk and HT?

Does anyone have a recommendation for a UHF preamp suitable for use with an HT and an Arrow? I always wish I had one when I listen for SO-50... it seems like it ought to be inline with BNC connectors and battery powered to maintain portability...

Thanks in advance!
