VHF, in full very high frequency, conventionally defined portion of the electromagnetic spectrum including any radiation with a wavelength between 1 and 10 metres and a frequency between 300 and 30 megahertz . VHF signals are widely employed for television and radio transmissions.

The VHF antenna P/N 2448-88-00 is an airborne communication antenna capable of transmitting and receiving signals in the VHF band from 118 to 156 MHz (extended) including VDL mode 2 . Designed for high-performance and wide-body aircraft, the VHF antenna has a compact design for reduced drag.

Aviation communication has five types: verbal, nonverbal, written, written and graphics, and human-machine and machine-machine communications . Verbal communication or speech is the most common communication medium used in an aircraft or in the aviation industry.

VHF radios are used for communications between aircraft and air traffic control (ATC), as well as air-to-air communication between aircraft . When using VHF, each party transmits and receives on the same channel. Only one party can transmit at any one time.
