Scannermaster LNA-AIR Pre-Amp?, Anybody tried one?
« on: November 11, 2010, 09:44:41 PM »
Anybody tried the Scannermaster LNA-AIR pre-amplifier?  

http://www.scannermaster.com/LNA_AIR_Pre_Amplifier_p/24-531043.htm

Not much on the net or forums as far as far a reviews go.  Was it worth it?  Wondering if it's GaAs FET? What power supply and or injector did you use?  Thanks ahead of time!

:D

Works fine.  This power injector works well:

or you can build your own.

I believe it is a GaAsFET.  Don't find too many MOSFETs in use these days - GaAS is cheap now.

Thanks Dave!, haven't bought a preamp since building a repeater in the 80's,  :lol: Angle Linear GaAs was the "in" thing then.

 I Think I'll try one of these on my airband yagi just for fun.
