FAQ

Q:What are the key features or characteristics of your products?
A:1.

The antenna section adopts a multi-feed point design scheme to ensure the coincidence of the phase center and the geometric center, thereby minimizing the influence of the antenna on measurement errors.2.

The antenna incorporates lightning protection design to ensure its normal operation even in harsh environments at high altitudes.3.

The antenna unit features high gain and a wide directional pattern beam, ensuring effective reception of low-elevation angle signals and enabling it to operate normally in scenarios with severe obstructions.4.

The radome is resistant to high and low-temperature shocks, providing a guarantee for the antenna's long-term operation in the field.
