![]() ![]() Although they don't look like it they are vertically polarized. Most do not perform as wide as the manufacturer claims but they do cover a very wide range very well. Sadly, the manufacturer will typically skimp on materials and size, making the antenna too small, so performance down at 470 is worse than it should be (that's TV channel 14) and better at the top than it needs to be. So it was built for 470 through 700 (the current full U.S. A "bow tie" antenna which is a version of the biconical generally exhibits increasing sensitivity as frequency increases, up to a limit. They often do a good job for 700, 800, and even 900 MHz just by the nature of their design. I could argue for a range of frequencies a piece of scrap wire sticking up outside is better than any commercial antenna used indoors. Foil-backed vapor barrier wall sheathing can block tremendous amount of signal. This is why outdoor antennas work so much better, generally. ![]() Plus materials in the structure are always problematic. However, some may be more susceptible to performance changes than others when in proximity to other objects. Indoor versus outdoor doesn't really matter for what the antenna is. North American television frequencies - Wikipedia, the free encyclopedia Here's why TV antennas work with scanners (scroll down to the Channel Chart and look at the frequencies). You just need to find one with more gain on UHF and get it into a good location (away from your computer). Terk HD-TVA Indoor HDTV Amplified UHF/VHF TV Antenna (HD-TVA) from Solid Signal)Īs you discovered with 800 mHz, TV antennas do pretty well with scanners. Or if most of what you want to listen to is in a single general direction, get this and turn it vertical. Winegard 8-Bay UHF Prostar 1000 High Definition TV Antenna (HD-8800) from Solid Signal What may be an improvement for you is simply a larger indoor TV antenna that has better gain for UHF than the leaf antenna. You wrote that 800 mHz is fine and that you are having trouble with UHF being weak. How big is the flat leaf HDTV antenna? If it's too small it may not really be doing that well with UHF. Is the flat leaf HDTV antenna in a window facing the city from which you are trying to pick up UHF? If that's correct then a couple of questions come to mind, i. I think what you meant is that you are using an HDTV flat "leaf" antenna for your scanner (?). ![]()
