An indoor antenna is a type of radio or TV antenna placed indoors, as opposed to being mounted on the roof. They are usually considered a simple and cheap solution to receive transmissions. An indoor antenna is prone to picking up electrical noise, but digital broadcasts are resistant to this noise.
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]
Telephone exchange with later antennas mounted higher for antifade. Antenna diversity, also known as space diversity or spatial diversity, is any one of several wireless diversity schemes that uses two or more antennas to improve the quality and reliability of a wireless link.
The Apple TV is designed to work with the Apple Wireless Keyboard or the Apple Magic Keyboard. [citation needed] Apple TV with and without tvOS supports closed captioning, so the deaf or hard of hearing can properly watch TV episodes and feature-length movies. Compatible episodes and movies are denoted with a CC (closed captioning) or SDH ...
Belling-Lee connectors Flex Type F connectors. A TV aerial plug is a connector used to connect coaxial cables with each other and with terrestrial VHF/UHF roof antennas, antenna signal amplifiers, CATV distribution equipment, TV sets and FM / DAB-radio receivers.
[6] [7] [8] Antenna may refer broadly to an entire assembly including support structure, enclosure (if any), etc., in addition to the actual RF current-carrying components. A receiving antenna may include not only the passive metal receiving elements, but also an integrated preamplifier or mixer, especially at and above microwave frequencies.
It is not necessary for an antenna to be resonant to transmit well, rather resonance is preferred to easily feed power to it; using a transmatch may make feeding power to an antenna on its nonresonant frequencies possible. [7] [8] [6] Some "doublets" are carefully sized to avoid resonance, in order to make impedance matching less challenging ...
To correctly form a beam, the transmitter needs to understand the characteristics of the channel. This process is called channel sounding or channel estimation . A known signal is sent to the mobile device that enables it to build a picture of the channel environment.
