Hi Chris
I think others have pretty well answered your questions. My gut feel is that given the manufacturer even mentions NF is a good thing. ie those that don't may be of poor performance in this area. As others have seen be careful of overload due to closer stations. I once lived in a VHF TV area where signals on 165/180MHz were strong but most people also wanted one on about 49MHz. Many a preamp had problems with the strong stations. I ended up setting up some 1/4 stubs on the preamp input that notched the strong signals enough to stop the bleed through. Cheers Bob szilagyic wrote: I have (for reasons that you mentioned) been thinking about replacing the preamp (Radio Shack 30 dB). The manual for it doesn't give the specs for noise, or anything useful for that matter. I have been looking at a Winegard AP-8275 (29 dB gain VHF, 28 dB gain UHF, 2.9 dB noise VHF, 2.8 dB noise UHF). Would this be a good alternative as far as a low noise amp?? We do not live near any stations, I believe the closest is 15 miles, so I am thinking a high gain preamp would be a good fit. ---- |
