Overview

The TOXU KC.EX.00100 is a multi-constellation, multi-band active GNSS antenna designed for professional positioning and measurement systems operating in outdoor environments.

The antenna supports compatible GPS L1/L2/L5, GLONASS L1/L2, BDS B1/B2/B3, and Galileo E1/E5b signals. It can be used with suitable multi-band GNSS and RTK receivers for surveying, mapping, precision agriculture, machine control, deformation monitoring, vehicle testing, autonomous equipment, outdoor robotics, and reference-station applications.

A multi-feed antenna structure is used to provide stable phase-center performance. The available specification lists a phase-center error of ±2mm and an axial ratio of no more than 3dB.

The integrated low-noise amplifier provides a specified gain of 40±2dB with a noise figure of no more than 2.0dB. The active circuit operates from 3.3V to 12.0V DC and consumes no more than 45mA.

The antenna uses right-hand circular polarization and a nominal 50-ohm RF interface. Its standard configuration includes a TNC male connector and a 5/8"-11UNC mounting thread.

The KC.EX.00100 measures Φ154 × 64.2mm and weighs no more than 300g. Its IP67-rated enclosure supports outdoor installation when the antenna, mating connector, cable joint, and mounting structure are properly installed and sealed.

The available specification lists compatibility with UM482, UM960, UM980, and UM982 GNSS modules. Compatibility with other receivers should be evaluated according to supported frequencies, antenna-bias voltage, available current, connector type, and RF input requirements.

The KC.EX.00100 is an active GNSS antenna only. It receives and amplifies satellite signals but does not calculate position, process correction data, or provide RTK accuracy independently.

System Integration

The KC.EX.00100 must be connected to a compatible multi-band GNSS or RTK receiver supporting the required GPS, GLONASS, BDS, and Galileo signals.

The antenna requires 3.3–12.0V DC bias power with sufficient current capacity. Bias power is normally supplied through the RF cable by the connected receiver or a compatible external bias-tee circuit.

Before connection, confirm the receiver’s antenna-bias voltage, available current, short-circuit protection, active-antenna detection, input impedance, and supported frequency bands.

The standard antenna uses a TNC male connector. The mating coaxial cable assembly should therefore use a compatible TNC female connector and a nominal 50-ohm cable.

Cable type and length should be selected according to the required installation distance because coaxial-cable insertion loss can reduce the signal level delivered to the receiver.

The 5/8"-11UNC thread supports installation on compatible survey poles, tripods, brackets, and mounting adapters. Confirm thread compatibility and mechanical clearance before installation.

For optimum reception, install the antenna horizontally with the upper radome facing the sky and provide the clearest practical sky view.

Keep the antenna away from metal obstructions, transmitting antennas, motors, high-current cables, switching power supplies, digital clock sources, and other potential sources of blockage, reflection, or electromagnetic interference.

The IP67 rating applies to the antenna enclosure under the specified product configuration. The mating connector, cable joint, mounting interface, and complete equipment enclosure must be sealed and protected separately.

For RTK operation, the connected receiver must receive valid compatible correction data from a base station, NTRIP service, radio modem, cellular modem, or another correction source.

Final positioning performance must be verified on the customer’s completed equipment because antenna installation, receiver configuration, correction-data quality, satellite visibility, cable loss, multipath, and electromagnetic interference can affect results.
