RE: [Repeater-Builder] question for Group on Mastr III
Any preamp like advanced receiver research would be suitable assuming one was needed. I have never seen a Mastr III that needs a preamp. unless maybe a tower top amp to recover feedline loss.. The front end has an awful low noise figure to start with..

I need to know if there is a preamp for receive for a G.E. Mastr III vhf in ham band 146.xxx. This is part of a recommendation I need to submit and you guys know the answer a lot faster than me trying to find it . Thanks Joe Landers Ke4eue image001.jpgimage002.jpg
Re: [Repeater-Builder] question for Group on Mastr III
I do not believe there is a factory pre-amp made for this unit. I believe factory spec is 0.35uV for 12dB SINAD. If you decide a pre-amp is needed I'd stay away from the super high gain GaAs FET type. I'd go with something in the 6 - 12dB gain range preferable with a helical front end.
