Overview

The TOXU KC.GA.00100 is an active external GNSS antenna designed for compatible vehicle navigation, positioning, tracking, telematics, and industrial terminal equipment.

The antenna supports GPS L1 at 1575.42MHz and BDS B1 at 1561.098MHz. It combines a 25 × 25 × 4mm ceramic antenna element with an internal two-stage amplification circuit to support GNSS signal reception through the standard 1.5m coaxial cable.

The available product drawing specifies an active gain of 28dB and a VSWR of ≤2.0. The value must be described as active gain in dB and must not be presented as 28dBi passive antenna-element gain.

The KC.GA.00100 uses a compact black housing measuring approximately 37 × 34.2 × 13mm. A genuine 3M double-sided adhesive layer on the bottom supports installation on clean, flat, and compatible equipment or vehicle surfaces.

The standard configuration includes a 1500±30mm RG174 coaxial cable and a blue FAKRA-C female connector. The keyed connector structure helps prevent incorrect mating and supports secure integration with compatible automotive GNSS receivers.

This product is an active GNSS antenna and requires bias power from a compatible receiver through the RF cable. It does not contain a GNSS receiver and cannot calculate position independently.

Key Features

GPS L1 and BDS B1 Signal Support

Supports GPS L1 at 1575.42MHz and BDS B1 at 1561.098MHz for compatible satellite navigation receivers.

Active GNSS Antenna Design

The integrated amplification circuit strengthens received GNSS signals before transmission through the RG174 coaxial cable.

Two-Stage Amplification Circuit

The internal PCB uses a two-stage amplifier design together with a filtering circuit for active GNSS signal reception.

28dB Specified Active Gain

The available product drawing specifies an active gain of 28dB for connection to compatible powered GNSS antenna inputs.

VSWR of ≤2.0

The specified VSWR is ≤2.0 at the supported GNSS frequencies under the defined test conditions.

3M Self-Adhesive Mounting

The adhesive backing supports installation on clean and flat surfaces without requiring a magnetic base or mounting hole.

1.5m RG174 Coaxial Cable

The standard finished cable length is 1500±30mm, providing flexible routing within vehicles and equipment installations.

Blue FAKRA-C Female Connector

The standard blue FAKRA-C female connector provides a keyed and secure RF connection for compatible automotive and industrial GNSS equipment.

Compact External Housing

The approximately 37 × 34.2 × 13mm black housing is suitable for applications requiring a low-profile external GNSS antenna.

-40°C to +85°C Temperature Range

The specified operating and storage temperature range supports demanding vehicle and industrial environments, subject to final application validation.

OEM Configuration Support

Cable length, connector type, connector code, housing label, packaging, and RF configuration can be evaluated according to customer requirements.

Technical Specifications

The available engineering drawing labels the gain value as 28dBi. Because the KC.GA.00100 contains an active two-stage amplification circuit, the value is presented on this page as 28dB active gain rather than passive antenna gain.

The available materials do not specify the LNA operating voltage, operating current, noise figure, out-of-band rejection, passive ceramic-element gain, or IP protection rating. These parameters must not be added until supported by an approved RF specification or test report.

Dimension Drawing

The standard KC.GA.00100 housing measures approximately 37±0.5mm in length, 34.2±0.5mm in width, and 13±0.5mm in height. The standard finished RG174 cable length is 1500±30mm.

The separate cable-processing drawing specifies a raw cutting length of 1530±30mm. This is a manufacturing dimension and is not the finished product cable length shown to customers.

Housing dimensions, connector coding, cable length, installation clearance, and adhesive mounting area should be confirmed against the approved drawing and sample before volume production.

Applications

• Vehicle Navigation Systems

• Automotive Positioning Terminals

• Telematics Control Units

• Fleet Management Equipment

• GPS and BDS Tracking Devices

• Vehicle-Mounted GNSS Receivers

• Industrial Positioning Terminals

• Asset Tracking Equipment

• Remote-Monitoring Devices

• Navigation and Timing Equipment

• Embedded Systems Requiring an External GNSS Antenna

System Integration

The KC.GA.00100 is an active GNSS antenna containing an integrated amplification circuit. It should be connected to a GNSS receiver input capable of supplying antenna bias power through the RF cable.

The available engineering materials do not specify the required operating voltage or current. These electrical parameters must be confirmed before connecting the antenna to a GNSS module, receiver board, telematics control unit, or customer-designed PCBA.

The connected receiver must support GPS L1 at 1575.42MHz and/or BDS B1 at 1561.098MHz. The antenna cannot add GPS or BDS compatibility to a receiver that does not support the corresponding constellation and signal.

The standard blue FAKRA-C female connector must be connected to a mechanically compatible FAKRA-C male interface. Connector key code, color, gender, and center-contact configuration should all be confirmed before ordering.

The adhesive surface should be installed on a clean, dry, smooth, and compatible substrate. Dust, oil, moisture, curved surfaces, high surface roughness, and repeated removal may reduce adhesive strength.

For better GNSS signal reception, the antenna should be installed with a suitable view of the sky and away from high-power transmitters, switching power supplies, metal shielding structures, and other potential interference sources.

The antenna does not contain a GNSS receiver and does not calculate position independently. Positioning performance depends on the connected receiver, firmware, satellite visibility, antenna placement, electromagnetic environment, and complete system design.

This product supports GPS L1 and BDS B1 only. It should not be described as a multi-frequency L1/L2/L5 RTK antenna. RTK capability depends on the connected receiver, supported frequencies, correction service, firmware, and complete positioning system.

Final RF performance, positioning performance, connector compatibility, and adhesive reliability should be verified on the customer’s finished equipment before volume production.
