Price: $25.99 | Compatible Model: Leica GPS500, GPS1200, GS10/GS15, GRX1200, Gainflex UHF/GSM Radio, GAD34 3cm Antenna Arm
This industrial coaxial cable fixes typical field signal faults: weak RTK radio reception, intermittent antenna connection, signal attenuation, cracked original factory wiring, loose TNC connectors, and unstable data transmission between GNSS receivers and external survey antennas. Standard 2.8m length perfectly matches Leica original wiring layout with zero signal loss for all-day outdoor measurement.

Product Overview

The Leica GEV120 TNC coaxial cable (OEM part number 636959) is a core RF communication spare part engineered for Leica GNSS RTK survey systems. Constructed with full-shielded KSR195 50-ohm coaxial wire and thick wear-resistant PUR outer sheath, this replacement cable blocks electromagnetic interference from construction machinery, vehicles and power lines. Precision-machined dual TNC male connectors fully replicate factory pin layout, compatible with GAD34 antenna arms, external Gainflex radios and all Leica GPS series receivers without extra adapters.

Core Advantages & Practical Structural Design

• Standard 2.8m total length, flexible layout for base station and rover field setup
• Dual TNC male connectors, straight plug design for seamless antenna arm mounting
• Double-layer copper shielding, low signal attenuation, stable UHF/GSM radio signal output
• Reinforced strain relief at both connector ends, prevents wire fracture from repeated bending
• Weatherproof PUR cable jacket, resistant to rain, dust, UV rays and construction site abrasion
• 50-ohm standard impedance, fully compliant with Leica original radio signal specifications
• Compatible matching accessory: Trimble TSC3 / TSC2 Yellow Nylon Carrying Case ($25, 0.2kg, 18 × 12 × 10 cm)
• Lightweight coiled design, easily stored in the front pouch of survey controller carry bags

Stable Signal Transmission & Field Application Scenarios

Ideal for GNSS RTK topographic survey, construction stakeout, boundary mapping, deformation monitoring and engineering control network projects. The GEV120 coaxial cable links Leica GNSS receivers to external Gainflex antennas mounted on GAD34 3cm extension arms, eliminating signal blockage and extending radio transmission distance. Pair this TNC antenna cable with our high-visibility yellow nylon protective case to organize your data collector, antenna arm, serial wires and spare cables; heavy-duty belt loop supports waist carry for long-distance field survey missions.
