We have a Biconlog. We currently have a 22dB pre-amp which is fine for class A levels but a close to 10dB+ above the noise floor near 1Ghz for class B. Moving the amp to the antenna should gain us several dB due to cable loss. We are also considering upgrading to a 40dB pre-amp. Any issues with doing that?
In my original email I mentioned the desire of powering the pre-amp through the coax. Any issues with powering the pre-amp with a second dedicated coax just to supply dc power from a linear power supply? Thanks for the input.

I'm looking for a low noise Pre-Amp for Radiated Emissions 30Mhz to 1Ghz (or higher) with a gain of 20-30dB; but here's the catch. I want it to mount directly to the "N" connector on my BiLog Antenna and be powered by a downstream Power Supply box that sends DC down the coax. Just like how TV Antenna pre-amps work. Does anyone know of a turn-key over the counter product like this that is available? I know such a design can have great benefits and be plagued with troubles such as reflections so I know it has to be done right and done well. Any information would be most helpful.
