80W 400MHz-470MHz UHF FM Ham Radio Power Amplifier for Interphone Car 13.8V Description Baby introduction: This baby is especially suitable for car clubs and car lovers, on the car you use the handstand and amplifier composed of car platform, get off the car after taking your handstand to continue walking excursions, cozy! In the wild open places 80 watts of power with a good antenna allows you to easily cover 40-70KM! 2-5W handheld after this amplifier transmitting power up to 80W! Ordinary car radio power level is between 25-35W! Using this product you can directly PK car radio in the coverage area, more fierce than the car radio! It is worth paying attention to is the car radio and hand radio reception sensitivity difference is not big, so have this baby you have their own car radio. Technical parameters: Transmitting frequency: 400-470MHz Coverage of the full U-band Output power: 80W, at 460MHz, using a good linear power supply of 13.8V 30A Can output 90W, straight to 100W bull. Receiving loss: U-band 400-470 loss is better than 1dB, V-band 136-174 loss is better than 0.7dB. This amplifier supports UV section receiving, transmitting only can transmit U section! Receiving current: This amplifier does not consume any current when receiving, and the power supply automatically turns on when transmitting, so there is no need for a power switch. When transmitting, the power supply is automatically turned on, so there is no need for a power switch, everything is fully automatic! Input power: suitable for a variety of U-band 2-7W hand-held amplifier Power supply: 12-14V, the voltage is the standard vehicle voltage, the launch current 16A. So the power supply must be more fierce, you should buy 13.8V 30A or 50A Linear power supply. The power supply should be connected directly to the car battery, but not the cigarette lighter. The current is too high. Usage: As with other hand stage amplifiers in our store, it is very easy to use! Handset through a radio frequency cable connected to the amplifier input section of the gold-colored SMA female connector, the amplifier output end of the large M female connector car antenna seedlings stick can be. The power cord is red and black is negative! Use everyone will, very easy. If you do not understand very well can refer to the store 25W series of products use. Precautions (must see!!!) : 1 Any moment is prohibited without connecting the antenna to transmit, this will be in a very short period of time to damage the RF power devices! Repair costs are high, the amplifier all depends on the core power devices. 2 Prohibit the power supply is reversed, red is positive, black negative, reverse will be a large number of internal devices burned. Please be careful to confirm before connecting the power supply! 3 amplifier internal circuit is complex, please do not open and go to adjust the internal devices, amplifier once opened, not to accept any commitment to the store. 4 Antenna should be good parameters, indicators of normal general low VSWR and can withstand 100W power, prohibit a variety of frequency is not the right WIFI and FM, remote control and so on the antenna received on the amplifier, which may also burn the internal devices, resulting in unnecessary losses! 5 The amplifier high-power, high current requirements, should choose high-power power supply with high output current capacity, prohibit some 10A or smaller power supply to the amplifier, so that may be fired when the power supply, and then the bad power supply output voltage and then burned the amplifier and so on, resulting in losses! package ： 1pcx 80W 400MHz-470MHz UHF FM Ham Radio Power Amplifier for Interphone Car 13.8V If you have any questions, please contact us in time, we will help you deal with the problem for the first time.
