2. Very high frequency - Wikipedia

   en.wikipedia.org/wiki/Very_high_frequency

   Very high frequency (VHF) is the ITU designation [1] [2] [3] for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high ...

3. Antenna tuning hut - Wikipedia

   en.wikipedia.org/wiki/Antenna_tuning_hut

   An antenna tuning hut or helix house is a small shed at the base of a longwave or mediumwave radio transmitting antenna. It contains antenna tuner — radio equipment for coupling the power from the feedline to the antenna. [1] Alternative names include antenna tuning house, coupling hut, and dog house.

4. Antenna tuner - Wikipedia

   en.wikipedia.org/wiki/Antenna_tuner

   An antenna's impedance is different at different frequencies. An antenna tuner matches a radio with a fixed impedance (typically 50 Ohms for modern transceivers) to the combination of the feedline and the antenna; useful when the impedance seen at the input end of the feedline is unknown, complex, or otherwise different from the transceiver.

5. Tuner (radio) - Wikipedia

   en.wikipedia.org/wiki/Tuner_(radio)

   Marantz 2050L AM/FM stereo tuner (USA; 1978-1980) [1]. In electronics and radio, a tuner is a type of receiver subsystem that receives RF transmissions, such as AM or FM broadcasts, and converts the selected carrier frequency into a form suitable for further processing or output, such as to an amplifier or loudspeaker.

6. Pan-American television frequencies - Wikipedia

   en.wikipedia.org/wiki/Pan-American_television...

   The Pan-American television frequencies are different for terrestrial and cable television systems. Terrestrial television channels are divided into two bands: the VHF band which comprises channels 2 through 13 and occupies frequencies between 54 and 216 MHz, and the UHF band, which comprises channels 14 through 36 and occupies frequencies between 470 and 608 MHz.

7. ATSC tuner - Wikipedia

   en.wikipedia.org/wiki/ATSC_tuner

   An ATSC (Advanced Television Systems Committee) tuner, often called an ATSC receiver or HDTV tuner, is a type of television tuner that allows reception of digital television (DTV) television channels that use ATSC standards, as transmitted by television stations in North America (including parts of Central America) and South Korea.

8. AN/VRC-12 - Wikipedia

   en.wikipedia.org/wiki/AN/VRC-12

   The AN/VRC-12 is the lowest-numbered element of a family of vehicular VHF-FM synthesized vehicular radio communications systems developed by Avco Corporation [1] and introduced around 1963 and used extensively by the U.S. military during the Vietnam War and for many years after.

9. SINCGARS - Wikipedia

   en.wikipedia.org/wiki/SINCGARS

   The system is compatible with all current U.S. and allied VHF-frequency modulation (FM) radios in the SC, nonsecure mode. The SINCGARS operates on any of 2320 channels between 30 and 88 megahertz (MHz) with a channel separation of 25 kilohertz (kHz).
