400 - 470Mhz UHF radio power amplifier car radio transceiver 25W
Should pay attention to the problems in use
1 the power cord ban against, anti will burn, red to the anode, black connect the cathode
2 launch to meet good antenna, is prohibited without antenna launch, it will affect the power amplifier device life or burning device!!!!!
Product features:
This product has built-in automatic transceiver switching circuit and power amplifier, strengthen the power of radio emission, for receiving the machine adopts direct way with the antenna, receiving less than 1 db loss, the loss can be ignored, has no effect on receiving sensitivity. (hand machine factory has debugging to sensitivity can achieve the best sensitivity!)
Ordinary 2 w transmission power machine after amplification to 19 to 20 w, ordinary 5 w transmission power machine after amplification of 25 w. Make your hands stage immediately become a "car"
Especially suitable for drives to use, get on with the hand received power amplifier for car use, out of the car took to Taiwan to use, convenient and flexible, product features for the power switch is omitted, only launch the input of the rf signal power to open up to a few watts of power amplifier power, in addition there is no other way to let the start-up. When the receive power amplifier, fully automatic power off when no electricity. Whether this can let you never will care about the power supply has closed complex problems, such as manual. Launch the red indicator and the power light is bright, when receiving the light is put out.
Parameters:
Frequency range: 400 MHZ to 470 MHZ covering U all the frequency point
Transmission power: the largest 25 watt, 2 w input output 19-20 watts, 5 w output reaches maximum when input!
Receiving loss: better than 1 db, this value affects the receiving sensitivity can be ignored.
Power supply: 12-14 V, the higher the voltage, the transmission power, the greater the measured 25 watt is 13.8 V.
Power supply current: launch 3 a, do not use when receiving any current
Model is suitable for: all kinds of U hand machine and UV U section in the double section hand machines work patterns (such as TG - UV2).
Hand power: suitable for all kinds of transmission power in the hands of 2-10 watts
