What should I pay attention to when installing the antenna of the platform?

The factors to be considered when different antennas are erected are different. The home antenna mainly considers the signal acceptance problem, and the erection group of the vehicle antenna is related to the polarization waveform of its signal.

Generally, the polarization mode of the car GP upright antenna used by everyone is vertically polarized. If you have to use it horizontally, there is no problem if the signal strength is sufficient. However, if the signal is weak, the antenna cannot be very It is good to sense the electromagnetic wave emitted by the antenna of the other party, and the signal of the extension line direction is weakest at both ends of the antenna. The practical application is that the signal receiving efficiency is reduced, and the effective communication distance is greatly shortened.

The most common antennas are the suction cup and the card edge. The suction cup is easy to install and remove, but it is easy to grind paint. Even if you pack red silk, the advantage is that it can be placed in the center of the ground net for easy adjustment. The advantage of the card edge base is that it is fixed firmly, but the ground net is uneven.

Said the choice of the base also talk about the antenna connection line (feeder) problem, in order to ensure good communication quality, each part of the connection is very important, Z can guarantee the use of as few adapters as possible. At the same time, we must also pay attention to the material and thickness of the connecting line. The general erection is to use the cable that is matched with the bracket, but there are also those who pursue the extreme zhi using the fixed length connecting line of the diamond. Of course, Z is good.

It is also important to calculate the length of the cable. The connection cable of a typical four-door sedan is about 4 meters, which basically meets the needs of the front to rear trunk connection. If it is a recreational vehicle or a jeep, it may be a little longer. When purchasing, be sure to estimate the length of the cable. Do not use the connector to reduce the strength of the signal.

When everything is ready, choose a good erection position. The erection position of the antenna on the car can be divided into the front hood, the roof, and the rear trunk of the car. The installation of these different locations will have a certain signal attenuation in use, which is determined by the different erection methods and the reflection of the signal by the ground effect of the vehicle body. The most ideal erection position is to use a bracket in the middle of the car. Of course, if you use a suction cup, the effect will be good. Compared with this, the effect is slightly worse when the vehicle is placed at the rear of the trunk. Of course, there are also special circumstances. You can test your car radio according to different erection positions. Z is based on the actual measured data.

Due to the size limitation of the vehicle antenna, the efficiency is not very high, so the difference in the quality of the antenna will affect the entire communication process. Now the general vehicle antenna is divided into single and multi-segment. Single segment is cheap, but it is better if it is a multi-segment machine or a multi-segment antenna.

The position of the antenna is very important. According to relevant research, the antenna is placed in the center of the top of the cockpit, and the efficiency Z is high. Because the ground net is large and uniform, the position is high, and it can also be placed on the trunk, but the effect is more general.
