One of the most common problems was the return to VHF frequencies by stations that had used them when they were analog. Over 480 stations were broadcasting digitally on the VHF spectrum after the transition, up from only 216 on the frequencies before. Many antennas marketed for digital TV are designed for UHF, which most digital stations use ...
Thus, the frequency band dedicated to TV became between 470 MHz and 700 MHz (channels 14-52), whilst 4G LTE uses the frequency bands between 700 and 900 MHz (former TV channels 52 to 83), resulting in an interval separating the two bands (DTT and 4G) of about 1 MHz, so that there is a risk of interference [1] in the areas close to the 4G-LTE ...
A short antenna pole next to a house Multiple Yagi TV aerials. Antennas are commonly placed on rooftops and sometimes in attics. Placing an antenna indoors significantly attenuates the level of the available signal. [19] [20] Directional antennas must be pointed at the transmitter they are receiving; in most cases great accuracy is not needed ...
A simulated example of severe ghosting in an analog TV broadcast. In television, a ghost is a replica of the transmitted image, offset in position, that is superimposed on top of the main image. It is often caused when a TV signal travels by two different paths to a receiving antenna, with a slight difference in timing. [1]
In the United States, there are six "Local Channel" frequencies, also known as "graveyarders" where nearly every station on those frequencies has the same power and antenna pattern both day and night and, as a result of skywave propagation, there is normally massive co-channel interference in rural areas on these frequencies, often making it ...

For directional antennas, the Yagi antenna is the most widely used as a high gain or "beam" antenna. For television reception, the Yagi is used, as well as the log-periodic antenna due to its wider bandwidth. Helical and turnstile antennas are used for satellite communication since they employ circular polarization.
