Overview

The TOXU KC.GA.00102 is an active external GNSS antenna designed for compatible positioning, navigation, tracking, telematics, and industrial terminal equipment.

The antenna supports GPS L1 at 1575.42MHz and BDS B1 at 1561MHz. It uses a 25 × 25 × 4mm ceramic antenna element with right-hand circular polarization and an internal low-noise amplifier for active GNSS signal reception.

The available engineering drawing specifies a gain value of 28. Because this product contains an integrated LNA, the value is presented on this page as 28dB active gain rather than 28dBi passive antenna-element gain.

The KC.GA.00102 uses a compact mouse-style black housing measuring approximately 50.3 × 38.4 × 18mm. A 3M double-sided adhesive layer on the bottom supports installation on compatible clean and flat surfaces.

The standard configuration includes a 3000±30mm RG174 coaxial cable and a 90° right-angle SMA male connector with male center pin. The right-angle connector structure is suitable for installations with limited rear clearance around the receiver antenna port.

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

Key Features

GPS L1 and BDS B1 Signal Support

Supports GPS L1 at 1575.42MHz and BDS B1 at 1561MHz for compatible satellite navigation receivers.

Active GNSS Antenna Design

The integrated LNA strengthens received GNSS signals before transmission through the 3m coaxial cable.

28dB Specified Active Gain

The available engineering drawing specifies a 28dB active gain for use with compatible powered GNSS antenna inputs.

RHCP Ceramic Antenna Element

The internal 25 × 25 × 4mm ceramic antenna element uses right-hand circular polarization for compatible GPS and BDS signal reception.

VSWR of ≤2.0

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

3M Self-Adhesive Installation

The integrated adhesive layer supports installation on clean, dry, smooth, and compatible surfaces without using a magnetic base.

3m RG174 Coaxial Cable

The standard finished cable length is 3000±30mm, providing flexible routing within vehicles, equipment cabinets, and positioning terminals.

Right-Angle SMA Male Connector

The 90° SMA male connector with male center pin provides a threaded RF connection while reducing the installation space required behind the receiver port.

Compact Mouse-Style Housing

The approximately 50.3 × 38.4 × 18mm housing is suitable for equipment requiring a compact external GNSS antenna.

-20°C to +60°C Operating Range

The specified operating temperature range supports compatible vehicle, tracking, navigation, and industrial applications, subject to final system validation.

OEM Configuration Support

Cable length, cable type, connector configuration, housing label, packaging, and antenna tuning can be evaluated according to project requirements.

Technical Specifications

The available drawing describes the gain value as 28dBi. Because the KC.GA.00102 contains an integrated LNA, this value is presented as 28dB active gain and must not be interpreted as 28dBi passive ceramic antenna gain.

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

Dimension Drawing

The standard KC.GA.00102 housing measures approximately 50.3±1mm in length, 38.4±1mm in width, and 18±1mm in height. The standard finished RG174 cable length is 3000±30mm.

The separate production cable drawing specifies a raw cutting length of 3030±20mm. This is a manufacturing dimension and is not the finished cable length shown to customers.

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

Applications

• Vehicle Tracking Devices

• Fleet Management Terminals

• Vehicle Navigation Equipment

• GPS and BDS Positioning Receivers

• Telematics Control Units

• Asset Tracking Equipment

• Industrial Positioning Terminals

• Remote-Monitoring Devices

• Construction and Agricultural Machinery

• Navigation and Timing Equipment

• Embedded Equipment Requiring an External GNSS Antenna

System Integration

The KC.GA.00102 is an active antenna containing an integrated LNA. It should be connected to a GNSS receiver input capable of supplying the required 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 terminal, or customer-designed PCBA.

The connected receiver must support GPS L1 at 1575.42MHz and/or BDS B1 at 1561MHz. The antenna cannot add satellite-system compatibility to a receiver that does not support the corresponding signal.

The standard connector is a 90° SMA male with male center pin. It must be connected to a mechanically and electrically compatible SMA female antenna port.

The right-angle connector can reduce the space required behind the receiver, but cable routing should avoid excessive bending, pulling, twisting, and repeated mechanical stress close to the connector.

The 3M adhesive surface should be installed on a clean, dry, smooth, and compatible substrate. Dust, oil, moisture, rough surfaces, curved mounting areas, and repeated removal may reduce adhesive strength.

For improved 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 3m RG174 cable provides flexible installation but also introduces RF transmission loss. The integrated LNA helps compensate for cable loss, while final performance still depends on the receiver, antenna bias supply, connector condition, cable routing, and installation environment.

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 signals, correction data, 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.
