Factory OEM 50 Ohm Communication Cable 80%~95% Coverage LMR 195 200 240 300 400 Coaxial Cable

Product Description

50 ohm lmr195 lmr200 lmr240 lmr300 lmr400 low loss coaxial cable

LMR 195, 200, 240, 300, 400 low-loss coaxial cables have bare copper as the inner conductor, expanded polyethylene as the insulation, and aluminum foil and tinned copper braid for the outer conductor with a characteristic impedance of 50 ohms. Among them, the inner conductor diameter of LMR 195 is 0.94mm, and the outer diameter is 4.95mm; The inner conductor diameter of the LMR 200 is 1.12mm, and the outer diameter is also 4.95mm; LMR 240 inner conductor diameter 1.42mm, outer diameter 6.10mm; LMR 300 inner conductor diameter 1.78mm, outer diameter 7.62mm; The LMR 400 has an inner conductor diameter of 2.74mm and an outer diameter of 10.29mm. These cables have the characteristics of good flexibility, reduced attenuation, good consistency, good weather resistance, strong anti-interference ability, etc., and are widely used in mobile, microwave communications, wireless and fixed network creation, antenna systems and other fields.
