JCN228F

Antennas RF Overview

The JCN228F is a multi-band GNSS surveying antenna designed for high-precision positioning applications. It supports GPS L1/L2/L5, GLONASS G1/G2/G3, BeiDou B1/B2/B3, and Galileo E1/E5a/E5b frequencies. The unit features an integrated Low Noise Amplifier (LNA) and utilizes RHCP polarization to ensure signal integrity. Key electrical specifications include a 50Ω impedance, a VSWR range of 1.5 to 2:1, and a phase center error of ±2mm. Mechanical options include TNC or MCX male connectors with varying cable lengths.

Antennas RF Procurement Notes

Verify the specific connector type required, as documentation indicates variations between TNC and MCX male interfaces for this model. Confirm cable length specifications against project requirements. Ensure compatibility with existing receiver input impedance. Check lead time availability directly with JC Antenna distributors. Validate that the selected variant matches the intended frequency band support.

Antennas RF Selection Notes

Select this antenna when multi-constellation support is critical for accuracy. Consider the integrated LNA for long cable runs to minimize loss. Evaluate mechanical mounting constraints relative to the dome design. Compare phase center error tolerances against specific surveying standards. Verify connector compatibility with the target receiver hardware before purchase.

Antennas RF Part Context

The JCN228F belongs to JC Antenna's specialized GNSS product line focused on surveying and geodetic applications. It complements other models like the JCA228F and JCA247 within the manufacturer's portfolio. These antennas are engineered for professional use cases requiring stable phase centers and broad frequency coverage across GPS, GLONASS, Galileo, and BeiDou constellations.

Antennas RF Replacement Considerations

The JCA228F is a related active antenna variant from the same manufacturer. Both units serve similar GNSS surveying functions but may differ in connector types or specific gain characteristics. Cross-reference technical datasheets to ensure interface and performance compatibility before substitution.
