GPS+Beidou Timing Antenna Marine Antenna 38dBi
Product Introduction
GPS+Beidou Timing antenna is a type of antenna used to receive satellite signals. It can receive RHCP satellite signals in the GPS L1 and BD B1 frequency bands.
This antenna has the following features:
High gain: The active mushroom head antenna can provide higher signal gain and enhance the weak signal power of the received signal, thereby improving receiving sensitivity and signal quality.
High stability: The antenna is designed with high stability and can maintain stable performance under different environmental conditions. This means it can provide stable satellite signal reception in all weather conditions.
Highly stable phase center: The active mushroom head antenna has a highly stable phase center, that is, the phase center of the received signal remains stable within a certain time range. This is very important for positioning and navigation applications, since phase center stability directly affects measurement accuracy.
