Is TV a VHF or UHF?
UHF frequencies are used for both analog and digital television broadcasts. UHF channels are typically given higher channel numbers, like the US arrangement with VHF channels (initially) 1 to 13, and UHF channels (initially) numbered 14 to 83.
What is VHF on a TV?
Over-the-air TV signals are broadcast on two different bands, very high frequency (VHF) and ultrahigh frequency (UHF). VHF channels transmit at radio frequencies between 54 MHz and 216 MHz, while UHF channels come at much higher frequencies between 470 MHz and 890 MHz.

What channels should you use for regular conversations? Channels 68, 69, 71, 72, and 78A are considered non-commercial channels, and in most areas, 68 and 72 are commonly used by the recreational-boating community. But remember that the VHF is officially for “operational” purposes.
Is RF AM or FM?
As an example, at RF Solutions we actually use AM Modulation in our longstanding and popular 118 Remote Control Systems.
Why have you included a table of VHF/UHF/FM frequencies?
In order to help better identify signals of interest from ambient signals that might already be in the area, we have included a table of VHF, UHF, and FM frequencies, as a companion to our TDS-536 TV Dipole set, specifically designed for testing at these frequencies.
What is a UHF TV?
UHF television refers to the use of ultra high frequency radio to broadcast to your television set. This type of frequency can be used for both digital and analog broadcasts, and the VHF frequency band runs from 50 MHz to 225 MHz. When looking at your TV and the channels, the UHF channels will usually be numbered higher.
