JCB317L

Antennas RF Overview

The JCB317L is a dual-band GPS/BDS and LTE combination antenna designed for compact vehicle navigation and localization applications. It integrates GPS reception covering 1561.098 to 1575.42 MHz with Right-Hand Circular Polarization (RHCP) and a gain of 2 dBi at zenith, alongside an integrated Low Noise Amplifier (LNA) providing 28 dB gain. The LTE section supports frequency ranges of 698–960 MHz, 1.561–1.575 GHz, and 1.71–2.69 GHz. The unit features a 50 Ω impedance, RG174 cable with a straight SMA male connector, and ABS radome material. Mounting options include adhesive or magnetic bases, with a maximum height of 15.00 mm.

Antennas RF Procurement Notes

Verify the specific frequency band requirements against your target LTE network standards before procurement. Confirm that the integrated LNA power supply requirements align with your system design. Ensure the SMA straight male connector interface matches your host device's RF port. Validate the adhesive or magnetic mounting method suitability for the intended installation surface.

Antennas RF Selection Notes

Select this model when a combined solution for GNSS positioning and cellular data transmission is required in space-constrained environments. The integrated design reduces assembly complexity compared to separate antennas. Consider the 28 dB LNA gain benefit for weak signal environments. Verify compatibility with the supported GPS/BDS frequencies and the specific LTE bands needed for regional operation.
