Frekuensi radhio
Frekuensi radhio utawa gelombang radhio iku tegesé spektrum elektromagnetik yakuwi gelombang elektromagnetik sing diasilaké saka pangiriman arus bolak-balik ing siji antène. Frekuensi iki kalebu péranganing spektrum ing ngisor iki:
Jeneng band Cekakan band ITU Frekuensi Dawa gelombang < 3 Hz > 100,000 km Extremely low frequency ELF 1 3–30 Hz 100,000 km – 10,000 km Super low frequency SLF 2 30–300 Hz 10,000 km – 1000 km Ultra low frequency ULF 3 300–3000 Hz 1000 km – 100 km Very low frequency VLF 4 3–30 kHz 100 km – 10 km Low frequency LF 5 30–300 kHz 10 km – 1 km Medium frequency MF 6 300–3000 kHz 1 km – 100 m High frequency HF 7 3–30 MHz 100 m – 10 m Very high frequency VHF 8 30–300 MHz 10 m – 1 m Ultra high frequency UHF 9 300–3000 MHz 1 m – 100 mm Super high frequency SHF 10 3–30 GHz 100 mm – 10 mm Extremely high frequency EHF 11 30–300 GHz 10 mm – 1 mm Di atas 300 GHz < 1 mm
