LL400 Antenna Coax Cable
(CLF400, KSR400,®LMR400) Super Low Loss - 50Ω 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.
Super Low Loss LL400 Coax is made to length and is available with various connector options. Adapters also available.
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.
