Foamed or high-foamed trishield cable is recommended.
Impedance 75Ω must be used for coax cable connection and connector work.
Beware of deformation of cable due to high pressure over the cable.
Don’t pull the cable with too much force.
For DVR input/output, cables will be tied at the rear of the rack. If tied too tightly, inside/outside insulator can be

deformed so tie it loosely within cable’s curvature range.

For bigger distances, please use the GTH-L0011E extender from GRUNDIG.
