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:

Rough plot of Earth's atmospheric transmittance (or opacity) to various wavelengths of electromagnetic radiation, including radio waves.

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
