VHF signals cover 2 frequency bands. The Low-VHF band covers channels 2-6 and the High-VHF band covers channels 7-13 . Because these signal wavelengths are longer than UHF signals, they can more easily bend over and around certain obstructions in the terrain between the TV broadcast tower and the receiving TV antenna.
Read moreWhat is the UHF frequency range?
UHF, abbreviation of ultrahigh frequency, conventionally defined portion of the electromagnetic spectrum, encompassing radiations having a wavelength between 0.1 and 1 m and a frequency between 3,000 and 300 megahertz . UHF signals are used extensively in televison broadcasting.
Read moreWhich frequency is best for communication?
Digital communication systems such as Bluetooth and some of the 802.11 protocols operate in the low-gigahertz range, more specifically, at frequencies near 2.4 GHz . These are generally short-range systems, but they offer reliable communication and the high carrier frequency enables high data rates.

Read moreWhat are communication frequencies?
Nowadays, radio communication or radio frequency communication refers to wireless communication through the air with electromagnetic wave frequencies ranging from 3 kHz to 300 GHz . Wireless communication is now classified by the medium electromagnetic waves propagate through.
Read moreWhy high frequency is used in communication?
Originally Answered: Why do we use high frequency waves as carrier waves? HF (2 – 30 MHz) is used for long distance communications because the atmosphere acts to bend these rays and bounce them back towards earth, so that they can travel all over the world, using very modest power to do so .
Read moreWhat is S band and L band in radar?
L band radars operate on a wavelength of 15-30 cm and a frequency of 1-2 GHz. L band radars are mostly used for clear air turbulence studies. S band radars operate on a wavelength of 8-15 cm and a frequency of 2-4 GHz. Because of the wavelength and frequency, S band radars are not easily attenuated.
