TV Antenna Polarization

A

alg2468

What are the differences between TV transmitter antennas that are polarized horizontally, vertically, and circularily, and which is the best for achieving the best long range reception in for digital TV? I've read that circular polarization is best to achieve the maximum coverage area for digital TV reception - is that true?

Circular works equally well when received by a horizontal or vertical antenna. To my knowledge, they don't make a circular TV receive antenna. I use a horizontally antenna 7' UHF dish and get reliable HD at 70 miles. I'm pleased with my reception quality.
 
You can make a CP antenna out of a couple of yagis. Upside is better rejection of stuff you don't want. Downside is, if the station is using left hand CP, your antenna won't work very well. I don't kno wthe TV count, if any, but at one time about ten percent of FM antennas were LHCP as a part of the optimization process.
