With antennas (for TV or anything else), "amount of metal" (the more, the better) beats everything else you can do almost every time, with location being the second-most-important factor (the higher, the better, and away from other metal and appliances). You will do MUCH better, if you can get access, by putting a full-size outdoor antenna in the attic of your home, even lying on top of the rafters/insulation up there, pointed toward the stations you want to receive. All of that miscellaneous noise may not be on the exact TV station frequencies, but it can still mess up the general reception performance of a high-gain preamp. The catch with indoor antennas is that they will likely pick up lots of miscellaneous RF noise from nearby items, everything from laptop computers to microwave oven display panels, or the TV set itself. The reason is, as Tom just mentioned, that "higher gain" (or as you describe it "pull some serious power" ) is intended to be used with "lower overall signal strength on the whole band". Having said that, though, if you are intending to use any high-gain preamp with an indoor antenna, you might not have much success, I am afraid. That Channel Master, or any mast-mounted preamp, can easily be used indoors by putting a short piece of RG-6 cable from the preamp output to the connection marked "antenna" on the power supply, which is the piece that is always indoors. if you ever do i hope you will share the info here as i would be interested in something like that myself. not sure where you could find a schematic to build one. This being said if it was a set top booster that would eliminate some of the problems but the only one of these i ever saw was on ebay. i don't think most people would want to climb up on the roof to change tubes and it would have to be in a weather tight case which i think would present a heat problem using tubes. ![]() Most antenna boosters i ever heard of are mast mounted and for this reason i don't think they made tube type antenna boosters or if they did i never knew of anyone who had one. Hey all, I've been searching the internet and i'm coming up a blank, i want to build an antenna booster because we get horrible TV reception where i live, and my thinking was if i built one, i could get more power out of it than the ones that I'm finding online, I'd like to use tubes but I'm not finding anything schematics for what I'm wanting to do, wondering if anyone has a good schematic, i want to pull as much power as i can and id like something fairly more reliable tube wise that i can leave on 24/7 since we usually have a TV on somewhere in the house, at most I don't want to have to change more than every month or so, but i want to get as much life as i reasonably can. ![]()
