Radio waves have the longest wavelengths in the EM spectrum, according to NASA, ranging from about 0.04 inches (1 millimeter) to more than 62 miles (100 kilometers). They also have the lowest frequencies, from about 3,000 cycles per second, or 3 kilohertz, up to about 300 billion hertz, or 300 gigahertz.

Common radio frequency bands include the following: AM radio – 535 kilohertz to 1.7 megahertz . Short wave radio – bands from 5.9 megahertz to 26.1 megahertz. Citizens band (CB) radio – 26.96 megahertz to 27.41 megahertz. Television stations – 54 to 88 megahertz for channels 2 through 6.
Read moreWhat are best radio frequencies?
Two-Way Radio Frequencies Golden Rule The higher the frequency, the better the in-building penetration. This means a lower frequency like 150MHz in the VHF radio band will travel farther, and a higher frequency like 450MHz in the UHF radio band will work better inside of buildings.
