![]() Anonymous wrote: My low channels and high channels are coming in week (I especially would like to improve channel 49). I like in a small city of 130,000 population. We have Toronto aprox 40 miles north and Buffalo 40 miles south of us. I would to find a way to improve my TV signal. One of the things I would like to try is put a preamp on the antenna, but not sure what dB rating to use so I don't over amplify my signal (I don't want to improve some channels at the expense of other good channels). Any ideas? TV preamps are mainly intended to overcome feedline losses. They typically have rather high noise figure (6 dB or more). I doubt that a preamp alone will improve your reception significantly. What type of antenna are you using now and how high is it? Is your house on a hill or in a valley? What is the terrain between you and the stations? TV signals are basically line-of-sight. Antenna height is a huge factor in good reception. The Radio Shack antennas that have a log-periodic VHF section and a corner-reflector UHF section are pretty good. The bigger the antenna, the better it will work. Don't trust the "range" figures in their catalog. Get the antenna up at least 25-30 feet (a chimney mount works well). Use RG-6 coaxial cable to feed the antenna. You can probably get a good idea of what you need by looking at your neighbors' roofs! Since you're trying to receive signals from two different directions, you will need a rotator. There's no way around that (unless you want to install two separate antennas). Then, there's always cable TV. ;- Art Harris N2AH |
