Frekuensi radhio

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

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
