LMR-240 Unbeatable Low Loss Coaxial Cable
LMR-240 cable is a high-performance, 50-Ohm coaxial cable engineered to minimize signal attenuation while offering superior flexibility in a compact 0.24-inch diameter. It is the preferred upgrade for installations requiring the handling and size of RG-62 but with dramatically improved electrical performance. Designed for exceptional performance up to 6 GHz ensures maximum power delivery and signal integrity over short to medium cable runs, especially at high frequencies. The UV-resistant Polyethylene (PE) jacket provides a 20+ year life expectancy in harsh environmental conditions. Double-shielded construction (foil and braid) provides robust protection against electromagnetic interference (EMI).
Key Features
-
Ultra-Low Loss: Significantly outperforms RG-58, reducing signal loss by up to 40%, especially at higher frequencies.3 Essential for maintaining signal integrity over short to moderate runs.
-
Example Attenuation: 7.6 dB/100 ft (24.9 dB/100m) at 900 MH
-
-
Superior Shielding: Features a robust double-shielded design (Aluminum Tape and Tinned Copper Braid) providing >90 dB of RF shielding, ensuring maximum RFI/EMI rejection in high-interference environments.
-
Exceptional Flexibility: The flexible Foam PE dielectric and construction allow for a tight minimum installation bend radius of just (19.1 mm), making routing easy in confined spaces.
-
Outdoor & Weather Resistant: The standard LMR-240 utilizes a UV-resistant Polyethylene (PE) jacket for outstanding weatherability and a long service life, even in harsh outdoor conditions.
-
Broad Frequency Support: Rated for operation from DC up to 6 GHz, making it highly versatile for modern wireless systems.
