JCA234

Antennas RF Overview

The JCA234 is a high-accuracy GNSS dome antenna manufactured by JC Antenna. It supports multiple navigation systems including GPS, GLONASS, Galileo, and BeiDou. The device operates across two primary frequency ranges: 1559.052–1616 MHz for L-band signals and 1205.094–1278.75 MHz for additional bands. It features Right-Hand Circular Polarization (RHCP) with an axial ratio of ≤3dB at zenith and a Voltage Standing Wave Ratio (VSWR) of ≤2.0. The antenna provides a gain of 40dBi and utilizes a TNC-K screw mount interface.
