JCA231

Antennas RF Overview

The JCA231 is a high-accuracy GNSS active antenna designed for precision positioning applications. It supports multiple satellite navigation systems including GPS, GLONASS, Galileo, and BeiDou across L1 and L2 frequency bands. The component features right-hand circular polarization (RHCP) with a peak gain of 2dBi and a voltage standing wave ratio (V.S.W.R.) of ≤2.0. It operates at a standard impedance of 50Ω with a 360° horizontal coverage angle. The unit utilizes an SMA male connector and incorporates adhesive or magnetic mounting options to facilitate installation in vehicle and surveying equipment.
