75 Ohm Trunk and Distribution Cable Flooded for Underground QR540 Trunk Coaxial Cable 

DESCRIPTION
High-physics foamed coaxial cable is a semi-air insulated cable. The inner conductor is made of high-quality oxygen-free copper wire (or copper-clad aluminum wire or copper-clad steel wire);The mutually closed air holes, the adhesion between the insulation and the inner conductor is firm; the outer conductor is braided with aluminum foil longitudinally wrapped with aluminum-magnesium alloy wire or tinned copper wire; with a PVC or PE outer sheath.
Model:RG59,RG6,RG7,RG11,QR540

FEATURES
Low attenuation, high return loss;
good water resistance, aging resistance;

APPLICATIONS
