Description
LL400 Antenna Coax Cable
(CLF400, KSR400,®LMR400) Super Low Loss 50? Double Shielded 10.3mm
Best suited to Fixed-Wireless installations such as Office buildings and Homes.
Larger than ®LMR240 but lower loss and more rigid.
This version of coax is the same LL400 cable option supplied with our antenna kits and has SMA female connections on both ends. For other connectors and lengths see our Made to Order LL400 product.
Double shielded by one layer of Aluminium foil and one close-knit copper braid make for a low-loss coax with 10.3mm overall diameter.
Its low signal attenuation figures make it well suited for use at Cell Phone frequencies.
