HF/VHF/UHF refers to high frequency radio frequencies between 3 and 3000 MHz. Radio waves are widely used in modern technology, particularly in telecommunication. 

(HF) High frequency (3–30 MHz) is the band associated with shortwave broadcasts, citizens band radio, amateur radio and over-the-horizon aviation communications, RFID, over-the-horizon radar, automatic link establishment (ALE) / near-vertical incidence skywave (NVIS) radio communications, marine and mobile radio telephony.

(VHF) Very high frequency (30–300 MHz) is the band associated with television broadcasts, line-of-sight ground-to-aircraft and aircraft-to-aircraft communications, land mobile and maritime mobile communications, amateur radio, and weather radio.

(UHF) Ultra High Frequency (300–3,000 MHz) is the band associated with television broadcasts, microwave oven, microwave devices/communications, radio astronomy, mobile phones, wireless LAN, Bluetooth, ZigBee, GPS and two-way radios, such as land mobile, FRS and GMRS radios, amateur radio, satellite radio, Remote Control Systems, and ADSB.

Foxcom's HF/VHF/UHF Link offers a high performance, cost effective alternative to conventional coaxial-cabled systems for radio and TV signal distribution.
