The LMR cable series includes the ultra-flexible LMR-400, 50 Ohms coax cable with UV Resistant jacket. Great drop-in replacement for RG-8/9913 cables. Designed for antenna feeder jumper assemblies runs requiring a high-performance, flexible, low loss RF cable.
LMR-400 is a widely used low-loss flexible RF coaxial cable, originally introduced by Times Microwave (now part of the Amphenol Group) in the United States. It is primarily used for transmitting high-frequency radio signals and is commonly found in communication base stations, WiFi devices, and RF testing fields.
Impedance and Frequency: The standard impedance is 50 ohms, and the operating frequency range typically covers DC to 6GHz, with some enhanced models reaching up to 8GHz, making it suitable for high-frequency signal transmission.
Loss and Shielding: This is a low-loss cable with a dual-shield structure (aluminum foil + braided mesh) that provides a shielding effect of approximately 90dB, effectively reducing signal interference.
Physical specifications: The outer diameter is approximately 10.3mm (0.405 inches), with a solid copper-plated aluminum conductor and a foamed polyethylene insulation layer. The operating temperature generally ranges from -40°C to 85°C.
Flexible and Durable: Compared to traditional rigid feeder cables, LMR-400 offers superior flexibility, facilitating easy bending and installation. Its outdoor-grade sheath is UV-resistant, ensuring a design lifespan of up to 20 years.
