Why this antenna matters: builtin SAW filters reduce electromagnetic interference so you keep a clean, stable signal in electrically noisy environments. That prevents dropped or distorted navigation and communication signals and delivers reliable performance without signal latency. Key benefits: Interference resistant: integrated SAW filtering minimizes EMI from engines, radios, and nearby electronics so devices maintain accurate positioning and dependable connectivity. Fast, simple setup: standard TNC interface connects to major navigation systems and devices for a straightforward installation that can be completed in about 5 seconds. Durable in harsh conditions: aviationgrade aluminum housing and protective circuitry support continuous operation in extreme temperatures from 40°C to 85°C. Ready for mobile use: designed for vehicles and marine environments where vibration, dirt, and temperature extremes are common. What it does: provides a stable, lowlatency RF connection for navigation and communication equipment by combining interference suppression, a reliable TNC connection, and rugged construction. Compatibility and form factor: Uses a standard TNC connector compatible with most navigation systems and RF devices. Robust metal construction for long service life; compact external antenna design fits typical vehicle and vessel mounting locations. Typical applications: Fishing boats: maintains GPS and chartplotter signal integrity near onboard engines and electronics. Trucks and commercial vehicles: keeps route guidance and telematics data stable across long hauls and noisy electrical systems. Construction and utility vehicles: reliable positioning and communication on worksites with heavy machinery and EMI. Installation and reliability notes: Connect via the TNC interface to your navigation or RF device; no special adapters required. Designed for continuous operation across a wide temperature range and protected against voltage surges and transient noise by internal circuitry. Specifications summary: Filtering: builtin SAW filters for EMI suppression Connector: standard TNC interface Housing: aviationgrade aluminum Operating temperature: 40°C to 85°C Installation time: approx. 5 seconds This antenna is targeted for users who need a rugged, interferenceresistant RF solution for marine and vehicle navigation or communication systems.
