Overview

The TOXU KC.GA.00117 is an active external GNSS antenna designed for vehicle positioning, navigation, tracking, telematics, and compatible industrial positioning equipment.

The antenna operates across 1560–1580MHz, covering GPS L1 at 1575.42MHz and BDS B1 at 1561.098MHz. Its internal patch antenna provides right-hand circular polarization for compatible satellite navigation signal reception.

The passive patch antenna has a specified typical zenith gain of 3.0dBic at both 1561.098MHz and 1575.42MHz. An integrated low-noise amplifier provides 28dB typical gain with a noise figure below 1.5dB.

The complete antenna assembly, including the patch antenna, LNA, and cable, has a specified typical overall zenith gain of 29dBic. This overall value should not be confused with the passive patch-antenna gain.

The active circuit operates from a 3.3V antenna bias supply and consumes less than 20mA under the specified conditions. The connected GNSS receiver must therefore support active-antenna bias power through its RF input.

The KC.GA.00117 uses a compact black housing measuring approximately 45.98 × 36.94 × 15.29mm. A 3M double-sided adhesive layer on the bottom supports installation on compatible clean, dry, and flat surfaces.

The standard configuration includes a 300±15mm RG174 coaxial cable and a straight nickel-plated SMA male connector with male center pin.

The KC.GA.00117 is an active GNSS antenna only. It does not contain a GNSS receiver and cannot calculate position independently.

-40°C to +85°C Operating Range

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

OEM Customization Support

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

Technical Specifications

The 3.0dBic value refers to the passive patch antenna’s typical zenith gain. The 28dB value refers to the internal LNA gain, while the 29dBic value is the specified typical overall zenith gain measured through the antenna, LNA, and cable.

The available engineering materials do not provide an approved IP protection rating, waterproof test result, salt-spray rating, vibration rating, or UV-resistance specification. These claims should not be added until supported by approved test data.

Dimension Drawing

The standard KC.GA.00117 housing measures approximately 45.98±1.5mm in length, 36.94±1.5mm in width, and 15.29±1.5mm in height. The standard finished RG174 cable length is 300±15mm.

The drawing specifies an approximately 20±3mm heat-shrink section near the SMA connector. Connector structure, cable length, adhesive mounting area, and installation clearance should be confirmed against the approved drawing and sample before volume production.

System Integration

The KC.GA.00117 is an active GNSS antenna containing an integrated low-noise amplifier. It must be connected to a compatible GNSS receiver input capable of supplying 3.3V antenna bias power through the RF cable.

The connected receiver should support a current requirement of less than 20mA and provide suitable active-antenna monitoring and protection according to the complete system design.

The 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 signal.

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

The 3M adhesive base should be installed on a clean, dry, smooth, and compatible surface. Dust, oil, moisture, high surface roughness, curved surfaces, and repeated removal may reduce adhesive strength.

For improved satellite signal reception, install the antenna 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 cannot calculate position independently. Positioning performance depends on the connected receiver, firmware, satellite visibility, antenna placement, electromagnetic environment, and complete system design.

This product supports the GPS L1 and BDS B1 frequency region 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, connector compatibility, positioning performance, and adhesive reliability should be verified on the customer’s finished equipment before volume production.
