Why are some FRP antennas unsuitable for indoor use?915MHZ fiberglass antenna and 868mhz 915mhz lora antenna and915MHZ Antenna with magnetic base Many users believe that as long as the antenna gain is high, there will be strong communication quality, especially when There is a requirement to pass through the wall, so they are pursuing the absolute value of the antenna gain. However, inindoor household or industrial routers, the antenna selection is generally in the range of 2-5DBI, and high-gain antennas are rarely used. This is because on the one hand, the size of the high-gain antenna is generally large and it is inconvenient to install. On the other hand, the high-gain omnidirectional antenna, although the horizontal plane is omnidirectional radiation, but the radiation Angle coverage on the vertical plane is very narrow (the width of the lobe is small), which is counterproductive in the relatively short communication distance (explained in the paper). Therefore, antennas with a gain below 8dBi are generally selected for indoor coverage of short and medium distance.
