The dennysantennaservice antenna has quite a bit of structure dedicated to pulling in VHF TV channels.
There are no longer any VHF TV channels to pull in. That spectrum space has been reallocated to other services since the advent of HDTV.
HDTV gets by with a weaker signal than the old analog signals. It lives in the UHF part of the spectrum.
One of the better designs for those frequencies is the bow-tie antenna, with an amplifier at the antenna. Typically, this antenna has a bow tie shaped element, with a reflector screen behind it. For weaker signals, you can get models with two bow ties, one above the other. For weaker yet signals, you can get a four bow tie antenna.
The amplifier on the antenna is important because coaxial cable losses at UHF are very high. A little amplification before the coax solves that problem.
