How to choose a navigation GPS antenna? What are the selection criteria?

Introduction: Navigation GPS antennas put forward higher requirements for accurate mailboxes, which requires most manufacturers to make higher choices in raw materials or product design when choosing to produce this product. How to choose navigation gps antenna? You might as well take a look at it together.

　　1. Antenna input power

Simply speaking, the input power is the maximum input power that the navigation GPS antenna can withstand. Generally speaking, all antennas will have relevant input power restrictions. The power input to the antenna at the radio station cannot exceed the maximum endurance. In other words, it is best for them to be able to withstand 2/3 of the power.

　　2. Antenna pattern

The pattern of the navigation GPS antenna is also very important. If the pattern can be analyzed, at least the signal coverage can be quickly understood in a short time. The signal transmission results can be analyzed immediately to improve the final antenna connection effect. Especially when relying on various sky waves and ground waves to propagate signals, the antenna pattern can be set according to the existing antenna erection height.

　　3. Antenna before and after comparison

The front-to-back comparison of the navigation GPS antenna is also very important. The maximum value of the radio waves generated by the antenna or the contrast between the maximum values ​​can completely describe the directional characteristics of the radiation capability. The front-to-back contrast value of the antenna is relatively high, and it can concentrate more energy together when transmitting.

At present, there is no direct correlation between the efficiency or fluctuation value of each antenna, but they must be taken into consideration when making choices.
