VHF antennas and UHF antennas use very high frequency (VHF) and ultra-high frequency (UHF) signals for two-way radio, public safety, and commercial communications. VHF is the range of radio frequency (RF) signals from 30 to 300 MHz. … UHF is the range between 300 MHz and 3 GHz.
Do I need a UHF or VHF antenna for digital TV?
To receive DTV signals from all stations in the area, your antenna needs to be able to receive both VHF channels (channels 2-13) and UHF channels (channels 14-36). … Many of the antennas being sold as “HDTV Antennas” perform best at receiving UHF signals, but perform less well receiving VHF channels.
Are TV signals VHF or UHF?
… digital TV standard adopted in the UK and the rest of Europe is DVB-T (Digital Video Broadcasting Terrestrial) which uses 8 MHz wide frequency bands for its transmission. … From this chart it can be seen that the total UK interleaved spectrum, which is entirely in the UHF frequency range, is 256 MHz.
Are police radios UHF or VHF?
Police radios operate in a 700/800 MHz UHF band. This gives them a considerable amount of range which is pretty good in urban areas.
Does UHF TV still exist?
UHF generally had less clear signals, and for some markets, became the home of smaller broadcasters who were not willing to bid on the more coveted VHF allocations. These issues are greatly reduced with digital television, and today most over-the-air broadcasts take place on UHF, while VHF channels are being retired.
How far can a digital antenna reach?
In most countries power is limited to reduce interference from neighbor stations. Taking also into consideration the curvature of the earth and the average height and power of a receiving antenna, a typical high range of a transmitted TV signal, without obstructing hills, trees, or tall buildings, is 60-80 miles.
What direction should my antenna point?
Many antennas have odd shapes that make it difficult to determine where they are pointed. For traditional multiple element antennas, the end with the smaller elements should point toward the transmitter. You can usually determine an antenna’s direction by trial and error.
Should I use VHF or UHF?
VHF radios are suited for long distances in and outdoor use. UHF radios operate at a higher frequency. This makes them ideal for wireless communications that need to penetrate through buildings, walls, or concrete. UHF radios are suited for indoor communication solutions, where obstacles are easily penetrable.
Is over the air TV UHF or VHF?
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.
