(ACCESSORY XC)
Each Greyline LIT25 includes 25 ft. (7.6 m) or 50 ft. (15 m) continuous RG62AU coaxial Sensor Cable.
Additional RG62AU coaxial cable and Cable Junction Box (Option JB) may be spliced and extended up
to 500 ft (152 m) as required during installation. No adjustment is required when the sensor cable is
extended or shortened. Use only RG62AU (or RG62U) coaxial cable which is available from Greyline
Instruments or your local distributor. Nominal impedance of RG62AU cable is 93 ohms.
Extended sensor cable must be installed in metal conduit to prevent interference. Do not use BNC
