data link unstable or unable to launch.
GDL20 radio power supply: voltage 12-15V (typical 13.8V) RF transmitter power 25W, current
7.0A.
Radio transmits power: radio transmits power based on the voltage of the power supply, check
the voltage before use.
High and low power use: use low-power transmitter when low power can satisfy the operation as
high-power transmitter will exponentially consume battery power, excessive use will reduce
battery life. Install the radio station as high as possible.
Power corrugated coefficient: power ripple coefficient must be less than 40mV, the smaller the
ripple factor is, the smaller will the beam spectrum be and the higher communication quality will
be.
Power Connection: Power of positive and negative connected correctly.
Electromagnetic environment: Before using the radio, it is better to perform electromagnetic
environment measurement, to avoid the communications blackout.
Radio match antenna: the basic parameters of the antenna selection are the band width,
frequency, gain, directivity, impedance, VSWR and other indexes .Usually the effective
bandwidth of the antenna is 3-5MHz,antenna selecting should be based on the frequency bands
used by the to be selected channel. For the long-distance transmission, it is better to use a
directional antenna and high-gain antenna, and pay attention to the impedance of the antenna and
feeder to match with the Radio GDL20 antenna interface (50 ohms).
We recommend:
Recommend that you use plug-in battery which is more than 12/36Ah,the use of maintain a
regulated current of 10A during the operation.
Recommend that you charge it in time, do not overuse the battery, otherwise it will reduce
battery life.
Recommend that you replace the batteries after six months to a year, to ensure the radio distance.
