Re: Mast Mounted Preamps.



I use and recommend the SSB Electronics SP-2000 and SP-7000 GaAs FET 
preamps.  They switch RF without an external sequencer (200W on 2m, 100W 
on 70cm).  A high-Q helical bandpass filter reduces the chance of 
overload from your own transmit signal or other strong RF sources.  The 
enclosure is weatherproof, well-shielded, and designed for mast 
mounting.  They are expensive because they are made in Germany.
