4 FAQ
The antenna frequency must match the frequency of the wireless device, otherwise the communication effect will be
poor;
The lower the communication frequency and the longer the wavelength, the better the diffraction performance;
When there is a straight-line communication obstacle, the communication distance will be attenuated accordingly;
Please pay attention to the antenna radiation direction, the incorrect installation direction of the antenna leads to a
short transmission distance;
The ground absorbs radio waves, and the test result near the ground is poor. It is recommended to increase the
height;
Sea water has a strong ability to absorb radio waves, so the seaside test results are not good;
If there is a metal object near the antenna or placed in a metal shell, the signal attenuation will be very serious;
The poor impedance matching between the antenna and the communication device will lead to poor communication
effects.
