The overall height of the antenna is about 27mm with RP-SMA connector. It is suitable for broadband communication systems in the 2.45GHz frequency band, wireless hotspot coverage, mobile terminal equipment such as routers, APs, radio stations, network cards, smart TVs, etc.Please note: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 antenna installation direction is incorrect, resulting in a short transmission distance.The ground absorbs radio waves, and the test effect is poor near the ground. 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.
