Do they have ways to go say 300 miles now?
Actually, hundreds of DXers have documented picking up both UHF and VHF tv stations from thousands of miles away under ideal band conditions
Very true. In the 70s I lived in Milwaukee and we had a big Winegard VHF/UHF antenna with an Alliance tenna rotor on the roof of our house and we could get Chicago (WGN, WFLD) and Madison (WHA) on a regular basis and in the Summer western Michigan, northern Indiana and even Green Bay. And distant VHF stations were better than a weather radio, you knew storms were coming when that lightning interference and sparkling started showing up in the picture.Actually, hundreds of DXers have documented picking up both UHF and VHF tv stations from thousands of miles away under ideal band conditions but typical range is much shorter.
It all depends on the elevation of the TV towers, your elevation, obstructions, and what antenna system you have.
UHF tv signals easily go beyond line of sight distances and VHF signals go FAR beyond line of sight.
Many get 100 mile reception daily today
In the analog days i used to watch a low vhf tv station from over 200 miles away daily.
TV fool and other online signal locators will give you a fairly close estimate of the distances you can expect
True with analog but with digital broadcasting a regular large UHF/VHF rooftop antenna will receive equally front to back. My antenna not only pulls in everything due south from the Philly area but also everything due north from the Scranton/Wilkes-Barre area. It also pulls in everything from the Allentown/Bethlehem transmitters about 30 degrees SSE, all without using the rotor. My most recent rescan, due to the ever ongoing repack, I locked 73 channels.Unless the antenna comes with a functional rotator, that's clearly a deception. I have yet to see a wideband antenna that offers a 1:1 front-to-back ratio.
This is a false statement. Most all larger antennas have a front-to-back ratio that is much greater than unity. Analog .vs. digital has absolutely no impact on it.True with analog but with digital broadcasting a regular large UHF/VHF rooftop antenna will receive equally front to back.
That's incorrect. Analog signals consisted of a continuously variable amplitude signal while digital is a bitstream. The continuously variable signal required the antenna to be designed in such a way as to capture that signal as efficiently as possible and that efficient design made the antenna very directional. A bitstream has no such limitations. If that hunk of aluminum picks up those ones and zeros from any direction they will be captured perfectly.Digital signals are received at the antenna exactly as analog ones were.
The only difference is how the receiver treats them, not the antenna.

The content rides on a carrier either way. With NTSC, there was an AM carrier for video and an FM carrier for audio. What does your experience tell you about AM versus FM at the same frequency?Analog signals consisted of a continuously variable amplitude signal while digital is a bitstream.
