Price: $62.95 | Compatible Model: Leica GAD32 Telescopic Rod, GAD34 3cm Antenna Arm, GEV120 TNC Coaxial Cable, GS10/GS15/GS18 GNSS Receiver, GFU27 Satelline Radio, GPS1200 PDL Radio
This original GAT2 radio antenna fixes common RTK communication faults: weak UHF signal reception, short radio transmission distance, signal loss around buildings/trees, broken factory whip antennas, unstable base-rover data link and frequent RTK fixed solution dropouts on construction survey sites. Matches original factory TNC interface, perfectly forms a full antenna setup with GAD32 rod + GAD34 arm + GEV120 cable for stable long-distance field measurement.

Product Overview

The LEICA GAT2 Radio Antenna with OEM part number 667243 is an official Gainflex UHF whip antenna specially developed for Leica GNSS RTK survey systems. Covering standard 435–470MHz survey frequency band, it delivers high receiving sensitivity and wide signal coverage. The outer body adopts wear-resistant waterproof rubber coating, resisting outdoor UV rays, rain, dust and minor collision damage during all-day field work. Equipped with standard TNC male connector, it can be directly connected to GEV120 coaxial cable, and mounted on GAD34 offset arm fixed to GAD32 telescopic rod for elevated unobstructed signal reception.

Core Advantages & Practical Structural Design

• 435–470MHz full UHF frequency coverage, compatible with mainstream Leica Satelline & PDL radio modules
• High-gain Gainflex design, effectively extend RTK communication range in complex terrain
• Standard TNC male plug, seamless plug-in connection with GEV120 TNC coaxial cable without adapters
• Waterproof anti-aging rubber antenna rod, flexible and not easy to break under field vibration
• Lightweight compact size, easy disassembly and storage after daily survey tasks
• Perfect match for GAD34 3cm antenna arm + GAD32 3-section telescopic support rod complete mounting system
• Low signal attenuation design, keeps stable real-time differential data transmission between base station and rover
• Compatible matching accessory: Trimble TSC3 / TSC2 Yellow Nylon Carrying Case ($25, 0.2kg, 18 × 12 × 10 cm)
• Small enough to store in the front accessory pouch together with antenna arms, RF cables and screen protectors

Stable RTK Communication & Field Application Scenarios

Widely applied in GNSS RTK topographic mapping, construction stakeout, land boundary survey, engineering deformation monitoring, pipeline layout and control network measurement projects. When assembled with GAD32 telescopic rod, GAD34 offset arm and GEV120 coaxial cable, GAT2 antenna can be lifted above trees, construction machinery and building barriers to eliminate signal shielding, greatly improving fixed solution rate and continuous communication stability. Match this UHF antenna with our high-visibility yellow nylon protective controller case to organize all survey peripherals; the reinforced belt loop supports waist hanging for hands-free long-distance outdoor survey transport.
