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.
