Would you like to know the difference between a standard, old fashion TV antenna and a new Modern, HD Digital TV antenna... $50.00 (or some other number) yup they slap "Digita" Or :"HD" on the box they charge more. Well some do.. Occasionally there really IS a difference... I will explain.
First: The BEST RV antenna sold in the USA is the Winegard Sensar IV with the OPTIONAL Sensar Pro wall plate.. Oh there are others that brag like a politician but in real life tests. The Sensar IV is hard to beat (like impossible). (I will say in some locations the Jack will get more stations, but that is because you are close in and the transmitters are thus spread out.. Normally all the transmitters will be withing a couple degrees).
IN the old days of analog TV was transmitted on Channels, numbered 2-69,,, Today in the DIGITAL age, TV is transmitted on channels, 2-69,, Yup the very same frequencies (Channels) and that is ALL that the antenna cares about.. Though in the old days there were more on the 2-13 and not so many on the 14-69.. that has flitpped.. Which is why Winegard came out with the Wingman for the older Sensar II and III (improves UHF performance)
So the moral is this: Whatever TV antenna you have now IS an HDTV antenna No need for a special buy
Most of what is advertised now days for "Only 3 easy payments of 29.95, Used to sell for 29.95 OR LESS in the analog days. EXACT SAME ANTENNA.. I've seen people pay 100 bucks for a UHF only antenna that sold for 20 bucks not all that long ago...
Save your money.
