Description
LL240 Antenna Extension Cable – Description
(CLF240, KRL240,®LMR240) – Very Low Loss Double Shielded 6.1mm
Suitable for Mobile and Fixed-Wireless installations such as Vehicles, Caravanns, Offices Buildings and Homes.
Lower loss than the LL195 (®LMR195).
Flexible and double-shielded by one layer of Aluminium foil and one close-knit copper braid make for a low-loss coax with 6.1mm overall diameter. Its very-low signal attenuation figures make it well suited for use at Cell Phone frequencies.
