LMR-240-DB

LMR-240-DB stands for Direct Burial, Its primary feature is watertight construction. This cable is superior to standard LMR-240 for any installation where moisture, water, or underground burial is a concern. The key feature is the integration of a water-blocking compound (a flexible water-sealing agent) between the overall braid and the polyethylene (PE) jacket. If the outer jacket is compromised (e.g., from damage by wildlife or tools), the blocking agent flows to the breach, effectively re-sealing the cable and preventing moisture migration and internal corrosion.

Low Loss Performance: It maintains the core benefits of the standard LMR-240 series Ultra-Low Attenuation Significantly lower signal loss compared to traditional RG-type cables of similar size (e.g., RG-8X). This ensures maximum power transfer to your antenna. High Velocity of Propagation Typically around 83-84%, which is vital for time-sensitive applications like GPS. Rugged, UV-Resistant PE Jacket Built to withstand harsh outdoor environments, including sun exposure and extreme temperatures -40C +85C.

Ideal Applications

• Land Mobile Radio (LMR) / Two-Way Radio: Excellent for installations where cable must be routed underground or through wet conduits for public safety and commercial communication systems.
• GPS and Satellite Communications: The low-loss make it suitable for transmitting accurate timing and positioning data.
• Short Antenna Jumper Assemblies: Perfect for connections between equipment and antennas in outdoor enclosures or remote sites.
• Remote Monitoring/SCADA Systems: Ensures reliable, all-weather data transmission for utility and industrial control systems.
• Amateur (Ham) Radio: A preferred choice for hams needing durable, high-performance coax for outdoor antennas.
