If you have Line Of Sight to the towers you shouldn't need much gain at all, basically to make up for cable losses like 5-10 dB. If you're behind obstructions, that game changes a lot though. Instead of the 8275 I would use the AP-8700. There is less gain but more headroom and I suspect that will be more of an issue. http://www.winegard.com/offair/preamps.htm GG Hello and thanks for the reply! We are mainly concerned with stations that are all between 35 & 45 miles away (don't care about the one that's 15 miles away); and some seem to be weak as current signal strength is about half, and they drop from time to time. Given this, would the AP-8275 work well, or would you still recommend the AP-8700? I have an attenuator just in case. I really appreciate your feedback on this..... Thank you!!! -- Chris Again, I'm at 35 miles with line of sight to the transmitters and a low gain antenna. The reason I suggested the 8700 is the reduced gain compared to the 8275. Keep in mind that amplifiers are not a panacea and are wideband devices. Just because the local (15 mile ) station is on whatever channel doesn't mean it can't cause overload issues _many_ channel numbers away. At 35 miles with good coax 100-200 feet, I wouldn't expect to need any amplifiers at all, much less 29 dB worth but if you believe you need it, the 8700 should be more tolerant of overload issues. You might even need to put the attenuator _ahead_ of the amplifier to keep _it_ from overloading. GG |
