5) If the above steps can not solve the problem, please contact Viewpro technical
support staff.
Q20: After connecting Viewpro module, what if the transmission distance of the module
is short, which is not up to expectation?
Please follow the following steps:
1) Please verify whether the antenna and RF cable are installed correctly, check whether
they are Viewpro standard materials;
2) Please ensure that the antennas installation of air unit is not blocked by the payload,
and there is no obvious blocking at the ground unit near the antennas, and the antennas of the
air and ground units are perpendicular to the ground;
3) Please check whether the RF power is reduced, not to achieve full RF power;
4) Please check whether the downlink mode configuration is reasonable or not, the high-
speed downlink mode will significantly reduce the transmission distance;
5) Please check whether the working frequency is obviously interfered or not, Chapter 6.2
introduces how to select working frequency.
6) Please check whether there is serious obstruction between the air and the ground unit
during flying, and the complex geographical environment will affect the transmission distance;
7) If the above steps can not solve the problem, please contact Viewpro technical support
staff.
