Antennas
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 Char t lists all four th-position alpha characters and
corresponding frequency band.
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.
