The following is the answer to netizens (a must-see for novices)
1.Why is the fiberglass antenna not suitable for indoor use?
Answer: Many people may notice one thing, that islinksysOrdlinkSuch international brands generally only use7dbOr5db,2dbAntennas, but rarely see theirs on the market9dbOr a higher gain indoor omnidirectional antenna appears. According to our understanding, indoor use,7dbThe antenna has fully met the requirements,7dbThe above antennas, due to their smaller angles, cannot give full play to their advantages, and may be counterproductive when used indoors. So we recommend,9dbThe above omnidirectional antennas must be recommended to be used outdoors. As for some people say that indoor penetration is good, this statement cannot withstand verification, so don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t believe it too much.
2.Why is it called an omnidirectional antenna, and there is also a vertical angle?
Answer: Generally speaking, the omnidirectional antenna means: the horizontal radiation angle is360Antenna with a degree of vertical, it emits in a sector shape, and the angle is general6~15About degrees, the higher the gain, the smaller the vertical angle, for example,9dbAntenna, the radiation angle can be achieved14Around degrees, and the glass fiber reinforced plastic antenna can do8The left and right degree is the limit. For a more intuitive explanation, please refer to the figure below

3.Why in the same position,15dbAntenna reception is not as good as9dbOr is the effect of lower gain antennas good? The answer is shown in the figure below:![](https://img.alicdn.com/imgextra/i3/182048713/T2J2tkXhpaXXXXXXXX_!!182048713.jpg)
4.After reading the above questions, I am puzzled, what environment is suitable for FRP?
Answer: Because of the small vertical angle, it can only be6~8Therefore, glass fiber reinforced plastic antennas are widely used for wireless coverage in plain areas and wireless coverage in the same horizontal location. A position with a height difference is a signal blind zone.
HaveTips on the usage of FRP:
1, Antenna angle problem, need to adjust well, find the coverage area;
2, Many people are connected to ordinary routers or network cards(USBtype)Above, it seems that the effect is similar to the original antenna. In fact, it is true. The solutions are:1)Check whether the routing power is adjustable, not adjustable, try to increase the power, it can be used500mwAboveAPTo push2)Antenna and routing/Whether the leads between the network cards are too long, do not exceed2Meter, otherwise the standing wave is difficult to control.3)Whether there are strong magnetic fields in the surrounding area, such as repeaters, base stations, high-voltage equipment, etc.4)Don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t install it on the anti-theft netInside;
3, Installation environment, it is recommended to install in an open place, not indoors, let alone horizontally.
