RF Preamp
Re: RF Preamp
You shouldn't need a pre-amp on HF at all, as reception is limited by external noise. On VHF and above, you may need one if you are looking for very weak sigs like satellites etc, but the amplifier should preferably tuned to the frequency of interest (not wideband) or you can get overload and intermod effects. The RSP's are already very sensitive, so unless your feeder is very long and lossy you don't need an amp for most listening.

Ok, thanks for the info, on further looking the amp says it has a 30db gain from 01 to 2000mhz and it is powered by 12vdc so I will leave well enough alone, thanks much.
