What does RF mean on a smart TV?
(Radio Frequency in) Refers to coaxial sockets on the back of older TVs, VCRs and DVDs that accepted analog video signals. The RF in socket is typically receiving VHF/UHF signals from an antenna. Contrast with RF out. See F connector and RF. RF In.
What does RF antenna mean?
An RF antenna input is usually used to connect a VCR, DVD player, antenna, cable box or other device to the television set via a coaxial cable. These thick cables usually have screw-in heads to help keep the connection secure, so most RF antenna inputs look like small screws protruding out of the TV.

Radio Frequency out R. (Radio Frequency out) Refers to coaxial sockets on the back of set-top boxes, VCRs and DVDs that output analog video signals for older TVs that do not have composite video or component video inputs.
What is the difference between RF and digital?
Bandwidth: Analog signals require less bandwidth whereas digital signals require more bandwidth. However, in digital systems the hardware is flexible where RF Signals can be handled by simple, standardized receivers and transmitters, and the digital signal can be then dealt with in baseband or software.
What is the frequency of digital TV channels?
Terrestrial television channels are divided into two bands: the VHF band which comprises channels 2 through 13 and occupies frequencies between 54 through 216 MHz, and the UHF band, which comprises channels 14 through 51 and occupies frequencies between 470 and 700 MHz.
What are channels in frequency?
A channel is an agreed-upon set of specific frequencies with additional information included in the agreement. For example, in the amateur 2m and 70cm bands, a portion of the band is channelised and set aside for repeaters.
Are digital TV channels UHF or VHF?
The majority of digital TV stations currently broadcast in the UHF band, both because VHF was already filled largely with analog TV when the digital facilities were built and because of severe issues with impulse noise on digital low-VHF channels.
Why have I lost channels on my TV?
Missing channels are typically caused by antenna or set up faults. Please check that youve got your antenna cable connected properly to your TV, set top box or PVR.
