Benefits for GNSS Applications
Low Signal Attenuation
LMR-240 provides significantly lower signal loss than conventional coaxial cables, helping preserve weak satellite signals between the GNSS antenna and receiver.
Improved Positioning Accuracy
Maintains high-quality GNSS signal transmission, supporting reliable RTK fixes and centimetre-level positioning performance.
Flexible Installation
The smaller cable diameter and lightweight construction make it easier to route within vehicles, equipment enclosures, survey poles and monitoring stations.
Excellent Noise Immunity
Foil and braided shielding helps protect GNSS signals from interference generated by radios, cellular devices, power equipment and other RF sources.
Rugged Outdoor Performance
The UV-resistant jacket supports moisture exposure and demanding field conditions.
