412 Seamless Aluminum Tube Flooded Coaxial Cable
Description
This 412-type seamless aluminum tube flooded coaxial cable is suitable for CATV trunk line projects. The inner conductor uses copper-clad aluminum, and the outer conductor is a seamless aluminum tube, with the same thermal expansion coefficient and elastic modulus, reducing faults caused by pulling or bending. Compared to conventional cables, it has better shielding attenuation, higher return loss, and lower attenuation.
