What are UHF and VHF frequencies?

UHF(Ultra high frequency) and VHF(Very high frequency) are considered to be the low frequency bands which frequencies are VHF 140-180MHz and UHF 420-480MHz. These bands are used by various electronic devices in our daily life. UHF frequencies are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications. VHF frequencies are used for FM radio broadcasting, television broadcasting, two way land mobile radio systems (emergency, business, private use and military), long range data communication up to several tens of kilometers with radio modems, amateur radio, and marine communications. Air traffic control communications and air navigation systems (e.g. VOR, DME & ILS) work at distances of 100 kilometers or more to aircraft at cruising altitude. Also it should be mentioned that UHF and VHF frequencies are lower than GSM and GPS, so they couldn’t be blocked by those types of jammers.
