Description
CRYSTAL MOBILE – 5W COMPACT IN CAR UHF CB RADIO – DB477A
477MHZ 12V 5W TRANSCEIVER
This high powered unit features the new 80CH UHF Narrow Band. Backward compatible with the standard 40CH UHF (Wide-band). This unit is very compact and features a large LCD display with changeable backlighting colour. The CB radio has a heavy duty die cast aluminium chassis for rugged protection and efficient heat dissipation. It has a 12V line output used for muting compatible stereos when receiving a call from another transmitter. The automatic squelch has adjustable sensitivity control to help filter out annoying back-ground noise. Compact 155x112x55mm. 12Vdc. 5W. 477MHz

40CH Wide-Band & 80CH Narrow Band The ACMA (Australian Communications and Media Authority) restructured the UHF CB band and increase its capacity from 40 up to 80 channels. Older radios that operate on only 40 UHF-CB channels are “Wideband” radios and the newer radios that will operate on the 80 UHF-CB channels are “Narrowband” radios. Both Narrowband radios and Wideband radios can communicate together normally as always on the first 40 channels. Only the new Narrowband radios will have the additional channels up to channel 80.
