Notes:
1. About the power supply.
This radio's power output is high to 25W. 12V power D.C., at least 8A
is recommended to use. Please choose power D.C. With good
fluctuation coefficient and anti-interference ability. If you use switch
power supply, please keep the antenna far away from it to avoid
antenna's inference.
2.
About the antenna.
Please choose antenna compatible with your radio's frequency bank.
For long distance communication, directional and high gain antenna
would help to reach better effects. And also, please try to mount
antenna at higher place.
Antenna's and its cable's impedance should be accordance with
radio's (50Ω). If not, whole unit's performance will be affected and it
may damage the radio, too.
3. About antenna cable
Choose cable with 50 Ω impedance and low decay material. Make
sure it can be connected with radio and antenna successfully. Please
also consider waterproof and lightning arrester.
4. Heat emission
If the radio needs to transmit for long time, please pay attention to
transfer heat in time.
