[AK-VHF] [PNWVHFS] For Sale Preamps

[Edward R Cole]

I had one inquiry.

These are not preamps you can transmit thru.  To do that would 
require two coax relays or one transfer relay to provide a bypass 
path.  I do not have those.
ARR makes a preamp that will handle 25w. But they cost more than these.
