TV Antenna???

Whether the elements are long or short has nothing to do with whether it's "analog" or "digital." Do not confuse VHF with UHF.

Well analog channel 14 is (was) around 470 mhz, and the old 69 was around 800, so a UHF antenna, which are normally a very poor design anyhow, has to cover a lot of ground. But the frequency band HAS NOT CHANGED. UHF channels are still in the same range of frequencies that they always were. But there are MANY really poor, somewhat less than poor, nearly decent, almost good, and possibly just about good antenna designs. You DO have to get a good antenna if you are in a low signal area just as you always did.

A "Digital" antenna is no different, frequency band wise, than it ever was.

As I said, that's why you need to research what is needed for your area. In mine, the 3 Washington PBS digi channels are on VHF, and that is why I have a big 'ol yagi with a 14' boom hanging off the side of my tower. --currently not used. The other thing that can be confusing, is in some areas the big main bang of a station may be on VHF, but YOU may not be able to receive it, and instead are receiving a UHF translator.

(WA PBS 7 now has a relay on a local hill here on RF channel 26, but this is not the main transmitter on "Tower Mt" over in Spokane, and is the reason my VHF antenna is currently un needed)

In this area, for example, KXLY 4 (ABC) is transmitted on RF channel 13 as well as 40 and 41 (two UHF relay/ translators)
