Indoor antennas are designed to be located on top of or next to the television set, but are ideally placed near a window in a room and as high up as possible for the best reception. [1] The most common types of indoor antennas are the dipole [ 2 ] ("rabbit ears"), which work best for VHF channels, and loop antennas , which work best for UHF. [ 3 ]
(right) One of the first television broadcasting antennas, on the Empire State Building in New York City for NBC's experimental 46.5 MHz TV station W2XBS in 1939. Terrestrial television or over-the-air television ( OTA ) is a type of television broadcasting in which the content is transmitted via radio waves from the terrestrial (Earth-based ...
[9] [better source needed] A length of at least 20 metres (66 ft) of 75 Ω (50 Ω) cable is recommended for operation without a balun. [10] [11] A transmatch (antenna tuner) is not required to use this antenna near its nominal design frequency of 14 MHz, and judicious length adjustments can sometimes include one other frequency band. All other ...
The dishes were nearly 20 feet (6.1 m) in diameter, [2] were remote controlled, [3] and could only pick up HBO signals from one of two satellites. [ citation needed ] Originally, the dishes used for satellite TV reception were 12 to 16 feet in diameter and made of solid fiberglass with an embedded metal coating, with later models being 4 to 10 ...
This mast has two UHF antennas for receiving signals from different directions. The lower antenna is a bowtie array. The upper antenna is a Yagi design.. UHF television broadcasting is the use of ultra high frequency (UHF) radio for over-the-air transmission of television signals.

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. VHF analog signals travel further than UHF signals, but watchable VHF digital signals appear to have a more limited range ...
Transformers, autotransformers, and baluns are sometimes incorporated into the design of narrow band antenna tuners and antenna cabling connections. They will all usually have little effect on the resonant frequency of either the antenna or the narrow band transmitter circuits, but can widen the range of impedances that the antenna tuner can match, and/or convert between balanced and ...
