Benefits for GNSS Applications
Low Signal Loss
LMR-400 offers significantly lower attenuation than standard coaxial cables, helping preserve weak GNSS signals over long distances.
Improved RTK Performance
Maintains signal quality between the GNSS antenna and receiver, supporting stable RTK corrections and high-accuracy positioning.
Long-Distance Installation
Ideal where antennas must be mounted away from receivers, including rooftops, towers, masts and permanent base stations.
Superior Interference Rejection
High-quality shielding helps protect GNSS signals from electromagnetic interference generated by nearby radios, cellular equipment and power systems.
Reliable Outdoor Operation
The rugged UV-resistant jacket supports long-term operation in sun, moisture and varying temperatures.
