![]() I think an even 15 year old antenna could stand replacement. In any case, the connections--especially those out in the weather--should be inspected and probably redone, just on general principal. As other posters have mentioned, twinlead has less loss than coax, but all of the antenna preamplifiers that I've seen are set up for coax. A preamp mounted *on the antenna* before the transmission line might be indicated...given that all other components of the installation (antenna, feedline, all connections, alignment) are up to snuff. These are readily available and generally work well. Back when antennas were more common, a professional would have evaluated your situation with attention to details such as: 1) How far are you from the transmitters? (A high gain antenna is not indicated if the stations are close by.) 2) What direction are they from your location? (If there are several stations in several directions, an antenna rotator is indicated, even if the distance is not great. If they are in only a couple of directions, sometimes it's simpler to mount a second antenna to pick up the off-axis stations. There used to be antennas available which were cut--IOW, optimized--for a single channel. Sometimes they were available from the station itself--not likely these days.) 3) How high is the tower on which your antenna is mounted? (Generally the higher the better.) 4) What are the characteristics of the surrounding terrain. (You're gonna have trouble receiving a station which is on the other side of a mountain...or any other obstruction which interferes with direct 'line of sight' signal transmission between the antenna and transmitter, including buildings.) 5) What is the condition and alignment of the current installation? (It's entirely possible that the existing antenna can be better aimed to receive the problem station(s) more reliably. See above for condition caveats.) jak "lbbs" wrote in message ... Basically I looking for ways to improve my signal. I am satisfied with the 12 channel or so that we are presently getting and I don't what to pay for more channel with cable or dish. All I want is to get a 15% improvement or so in my TV signal. I get a fair TV signal now, but I have a couple of channel like 49 that my parents better then us. I received a few suggestions like replace my coax with RG6 wire and get an preamplifier at my old tower antenna. The antenna is 35 years old at most (that is the age of our house), 15 years at best). Anything else I can do to improve signal. I don't mind putting some money into it since it is a long term investment. Thanks. get better that we do.

If your are more than 15 miles or less than 100 miles from your TV transmitter a good antenna system is required, At these distances you must point your antenna with an accuracy of +/- 5 degrees to get a good signal. An Omnidirectional antenna works well up to about 10 miles but then so would a coathanger . I would have to assume that you are outside or beyond a cable TV, COGECO ? service area else why would you want to put up an expensive $200 antenna to get one station when you can get a satellite setup for ~ $100.00. If you live in a Metropolitan Area., I can understand trying to avoid cable fees. Your question about amplifiers fails to recognize something called Signal to Noise Ratio a weak signal usually implies low SNR, further amplification will bring in a stronger signal but also much more NOISE or snow. A better antenna will improve SNR ie. a stronger signal with the same amout of noise, noise being background atmospheric static which is always present in any signal. I would have to assume that you must be using a dial-up MODEM because this question doesn't make much sense if you are using a Cable MODEM and already have access to a Cable Service yukio . They could not explain it to me at the store. Second question is about buying one of those omnidirectional TV antennas that look like a flying saucer. I believe they have a built in amplifier. If I bought one should I use it in combination with my old indoor amplifier? Thanks a lot for your help. |
