With everything being digital now it more or less depends on how far you are from the signal.
uuuuuuuuuhhhhhhh what?Reception of any radio signal has always been dependent on the distance between transmitter and receiver, and how the signal has been modulated does not affect the path loss, although it can affect how much signal is needed to produce a useful outcome.
When commercial television broadcast stations in North America changed to the Advanced Television System Committee (ATSC) recommendation for transmission of their signal, one significant change implemented at the same time was the reallocation by the FCC of the lower VHF Television Band to other services. The effect of this was to move most television broadcast stations into the UHF Television Band, although some stations remained or relocated to the high-band of VHF Television. The influence of this on antenna design for broadcast television reception is that it is no longer useful for a TV antenna in North America to be designed for the low-VHF band; this reduces the size of the antenna significantly. If all the stations in your region are now UHF, you can use a-UHF-only antenna, which will be smaller than high-VHF and UHF combination antennas.
When stations shifted to the ATSC method of transmission, the FCC recomputed their anticipated coverage areas on the new channels they would be moving to. They also factored in the signal modulation technique and what signal level at the receiver the FCC thought necessary to produce the same coverage as under the prior method. The result is that the coverage areas are or should be the same as before, and, in many cases, they are better, that is, people now receive more stations than ever before.
In practice it has been observed that the ATSC signals are prone to problems created by multi-path reception. Omni-directional antennas are the most prone to problems with multi-path. Because of this, practical results are usually improved by use of directional antennas, not so much for the gain they produce but for the attenuation of multi-path signals.
Mr. Hebert is quite learned in the area of electronic esoterica, sometimes to a fault when dealing with us mere mortals.uuuuuuuuuhhhhhhh what?
