6. Antenna
The antenna is very important for RF communication, its performance will affect the communication
directly. Module needs antenna in 50ohm. Common antenna has rubber straight/ elbow/ foldable rod
and sucker antenna and etc. Users can order accordingly. To ensure module in the best performance,
we suggest to use the our antennas.
★
To ensure modules get the best performance, user must obey the following principles when
using the antennas：

Put the antenna away from the ground and obstacle as possible as you could；
If you choose the sucker antenna, pull straight the lead wire as possible as it can be, the sucker
under arches should be attached on the metal object；
