Ajetrays AR-450: technical guide vehicle-mounted UHF-two-way radio 45 W
Ajetrays AR-450 - vehicle-mounted UHF station 400-490 MHz with three power levels - 10, 25 and 45 W, 200 channels and a display. power supply 12 V. The station is put in service vehicles, tow trucks and equipment, where a powerful UHF communication is needed.
Power over distance
The power level is switched: at a short distance work at 10 W, at a long distance - at 45. The alarms are CTCSS, DCS, 2-Tone, 5-Tone and DTMF.
Frequency and registration
The range of 400-490 MHz captures LPD and PMR frequencies, but it is impossible to work on them with such power: dedicated frequencies and station registration are required for service communication at 10-45 W. For comparison, the unregistered PMR limit is only 0.5 W.
Power supply
Power supply only 12 V. In a 24V truck, you need a converter with a margin of current. VEGA 24 → 13.8 V (17 A long time).
Antenna and base installation
The antenna is not included in the kit - it is selected for the working frequency. From the catalog fits. MR-14U Its UHF portion 420-470 MHz covers a portion of the station’s range. For the basic installation need a storm discharger LP-350.
