Price: $46.99 | Compatible Receivers: Leica GS20, SR20, GS5, GS5+ GPS GNSS Rover; Matching Antennas: PG-A1, PG-S1, PG-A3 TNC GNSS Antennas; Cross-Compatible: Ashtech Promark 3/100/120/200, Topcon GRS-1
This OEM-spec GEV179 coaxial antenna cable solves field GNSS signal transmission failures: aged original coax causing satellite signal attenuation, generic low-shield wires leading to RTK fixed solution loss, loose TNC/Lemo connectors triggering intermittent signal drop, thin single-shield cable susceptible to construction machinery electromagnetic interference, cracked outer sheath moisture intrusion corroding inner conductor, and mismatched pinout third-party cables failing receiver antenna detection. Strictly follows Leica original RF impedance standard, double-shield RG174 coaxial core delivers low-loss stable satellite signal transmission between TNC GNSS antenna and GS20/SR20 rover receiver for all-day cadastral, highway and mine RTK survey work.

Product Overview
The Leica GEV179 dedicated GPS antenna coaxial cable with official OEM part number 731353 is a standardized RF signal lead exclusively designed for Leica GS20 / SR20 legacy GNSS receivers. Dual-end connector layout: straight TNC male plug for external survey antenna, 90-degree right-angle Lemo FFA.00 male bayonet lock plug matching GS series receiver built-in antenna port, ergonomic elbow design avoids cable bending stress during backpack pole mounting. Internal adopts double-layer braided copper shielding RG174 coaxial wire core, precise 50Ω RF impedance consistent with factory original specification to minimize satellite signal attenuation. Outer layer thickened black PUR anti-aging sheath, UV-resistant, mud-proof, low-temperature flexible without hardening in mountain/tunnel harsh environments. Molded multi-stage strain relief at both connector roots eliminates wire breakage after thousands of repeated bending, all metal connectors gold-plated anti-oxidation to maintain stable RF conduction long-term outdoor use.
Core Advantages & Practical Structural Design
- 1:1 OEM RF circuit & connector pinout fully consistent with factory original GEV179 cable, direct plug-and-play replacement for damaged original 731353 antenna cord
- Standard 1.2m/1.5m optional total length, moderate slack for backpack pole antenna layout without excessive messy winding or tight port tension
- Double-layer full copper braided shielding structure, strong anti-electromagnetic interference capability, effectively block vehicle engine, excavator and high-voltage power line signal noise preventing RTK fixed solution dropout
- Precision 50Ω RG174 coaxial inner core, ultra-low signal attenuation, guarantee stable multi-constellation satellite tracking under long-distance field measurement
- 90-degree elbow Lemo connector design, perfectly fit compact GS20/SR20 receiver side port, reduce cable folding wear compared to straight Lemo plugs
- Gold-plated TNC & Lemo metal contact terminals, anti-rust, anti-oxidation, no signal interruption caused by field mud abrasion and long-term storage oxidation
- Weatherproof flexible PUR outer jacket, wide operating temperature -20℃~+55℃, remain soft and crack-free in cold plateau and high-temperature construction sites
- Wide cross-brand compatibility: Leica GS20/SR20/GS5/GS5+, PG series TNC GNSS antennas; also compatible with Ashtech Promark series, Topcon GRS-1 survey GPS receivers
- Compatible matching accessory: Trimble TSC3 / TSC2 Yellow Nylon Carrying Case ($25, 0.2kg, 18 × 12 × 10 cm)
- Lightweight rollable round cable structure, easy to coil and store in instrument accessory pouch together with GEV data cables, GHT pole brackets and spare batteries
Stable GNSS RF Signal Field Survey Application Scenarios
Mandatory original RF transmission accessory for rural cadastral boundary mapping, highway & pipeline control network stakeout, open-pit mine topographic survey, foundation settlement deformation monitoring and small-scale construction RTK layout projects. Survey technicians connect TNC end to PG series GNSS antenna mounted on telescopic pole, plug right-angle Lemo elbow into GS20/SR20 rover receiver, realizing loss-free satellite signal transmission to maintain continuous fixed RTK solution all working day. Double shielding design avoids signal interference near construction heavy machinery; molded reinforced strain relief prevent cable fracture during backpack carrying and field transport vibration. Store this GEV179 antenna coaxial cable and other tiny survey peripherals in our high-visibility yellow nylon data collector case; reinforced canvas belt loop supports waist hanging for convenient cross-region field survey transport.
