TXGN-FPC-3308 Datasheet Copyright © 2019, Chengdu Qisol Technology Co., Ltd. clause 4 page Chapter 5 Frequently Asked Questions antenna frequency must match the frequency of the wireless device, otherwise the communication effect is not good; The lower the communication frequency and the longer the wavelength, the better the diffraction performance; When there is a straight-line communication barrier, the communication distance will be attenuated accordingly; Please pay attention to the radiation direction of the antenna, the antenna installation direction is incorrect, resulting in a short transmission distance; ground absorbs radio waves, and the test effect is poor near the ground, so it is recommended to increase the altitude; Seawater has a strong ability to absorb radio waves, so the seaside test effect is not good; If there is a metal object near the antenna or placed in a metal shell, the signal attenuation will be very serious; Poor impedance matching between the antenna and the communication equipment will lead to poor communication effect.
