Message: [QUOTE="Mr. Know it all, post: 19406, member: 3410"]Again,Television antenna's are usually tuned to receive certain frequency's well and all other frequency's withing the spectrum of television at a semi ok level.Local channels with a clear line of sight, will come in with little resistance as long as you use a antenna that is higher than average terrain.Beyond that point, it is a crap shoot.There is no such thing as a HDTV antenna.   Any UHF antenna will receive UHF signals and any VHF antenna will receive VHF signals and any combo UHF / VHF antenna will receive both.Some people seem to think that a HDTV antenna is cut to receive channels from 7 to 59.  That myth is a lie.  There are still television signals in the range of channel 2 - 6 in many markets and a good antenna will receive all the frequency's, unless you live somewhere - where there is no VHF signals present, then all you need is a good UHF antenna.If you had a UHF / VHF antenna and live within the service range and your antenna was still good, it might still work.  There is only one thing that you have to remember, that is that UHF digital signals are line of sight and your antenna needs to be pointed in a direct line with the transmitter to get the best reception.  That can only be done with a antenna rotor.The VHF digital signals are now low power and does not transmit well over long distances as did ANALOG VHF.The best antenna's are the ones that are manufactured with a cartridge box that directly connects the RG 6 wire F type terminal to the antenna.Cheap commercially made transformers usually fail within one year in any environment where there is cold weather, wet weather, high temperatures and UV light.   Many antenna's are junked - just because the terminals corroded on the lugs on the antenna or the transformer went bad.The only two options is to use a Winegard type antenna that has a cartridge box that seals the phasing lines from the weather and directly connects the antenna to the 75 ohm RG 6 wire.The other solution is to use a Channel Master type pre amplifier that directly connects the leads of the pre amp to the lugs on the driven element on the antenna which then eliminates the need for a matching transformer.A little bit of anti seize on the threads of the lugs and terminals and some RVT silicone sealer on the outside of the terminals and some good 3M electrical tape will keep the moisture out of the wire and give you years of service.RG 6 Wire does not wear out, it just gets moisture inside of it and then it deteriorates the signal inside of the wire.All television antennas in fringe areas should use Quad Shield due to it's low loss and better shielding against outside noise.[/QUOTE]
