Radio/Antenna Identification

An information label is attached to the back of your radio (chassis), just under the battery contacts. A radio model number is identified on this label. A typical model number might be H01SDC9AA1AN. The fourth position of the model number (in this case “S”) identifies the operating frequency band of the radio. The Radio Operating-Frequency Chart lists all fourth-position alpha characters and corresponding frequency band.

Radio Operating-Frequency Chart

Fourth-position	Frequency	Fourth-position	Frequency	Fourth-position	Frequency
Character	Band	Character	Band	Character	Band
K	136-178 MHz	R	403-470MHz	U	806-870MHz
		S	450-520MHz	W	896-941MHz

Antennas are frequency sensitive and are color coded according to the frequency range of the antenna. The color code indicator is the insulator in the center of the base of the antenna. The following illustrations and chart will help identify the antenna, antenna frequency range, and corresponding color code.

Refer to the Radio Operating-Frequency Chart and the Antenna Identification Chart to ensure that the match between your radio and antenna is correct.
