An antenna tuner, a matchbox, transmatch, antenna tuning unit (ATU), antenna coupler, or feedline coupler is a device connected between a radio transmitter or receiver and its antenna to improve power transfer between them by matching the impedance of the radio to the antenna's feedline. Antenna tuners are particularly important for use with ...
When the ATSC tuner does a channel scan, it finds the signal on channel 43, learns that this material is called "Channel 4", and remembers that mapping. The user can tune to "4", and the tuner will know to tune in 43. Before a scan is done, it may be possible to access the programs directly by manual tuning, by entering 43–1, 43–2...

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.

Some countries have also introduced digital television and ended analog over-the-air transmissions. Most new TVs feature a digital tuner which allows reception of digital over-the-air TV without need of an external device such a converter box. If using a TV set without a digital tuner, an external converter box must be purchased and used.
For example, at 1 MHz, the man-made noise might be 55 dB above the thermal noise floor. If a small loop antenna's loss is 50 dB (as if the antenna included a 50 dB attenuator), then the electrical inefficiency of that antenna will have little influence on the receiving system's signal-to-noise ratio. In contrast, at quieter frequencies at about ...
A magic eye tube or tuning indicator, in technical literature called an electron-ray indicator tube, [1] is a vacuum tube which gives a visual indication of the amplitude of an electronic signal, such as an audio output, radio-frequency signal strength, or other functions. [1]
