Re: [Repeater-Builder] GLB Preselector Preamp, Re: midland 13-509 220mhz to convert to repeater

For Years I used the GLB Preamp/Preselector on thefront end of my Midland 509 220Mhz  repeater the preamp stage is  an MRF-901  I think a Gasfet Preamp will create to much noise Bob Dengler wrote: At 8/2/2005 06:55 PM, you wrote: Joe wrote: I had an FM76 convered to a 220Mhz repeater and used a GLB preselector in front of the receiver. It helped a lot. Unfortunately, the GLB is no longer available. Are you sure? <http://www.aria-glb.com/products/reset_frames.htm?/products/preselector.htm> Kevin Anyone measure the noise figure of one of these units? Even with the GaAsFET preamp, the overall NF is going to be high if the helical resonator loss is too high (resistive loss = NF). Bob NO6B Yahoo!
