X-400 Low Loss Cable 3M, 5M, 10M 50Ohm Extension/Replacement Cables

PLEASE NOTE: These are sold as singular cables.

Our X-400 coaxial cable is perfect for all installations. The ultra low attenuation of <0.193dB per metre between DC and 3GHz means that almost no signal is lost in the cable. The tough PE jacket resists UV and provides excellent durability in harsh environments.

This cable is a direct replacement for RG-8, LMR-400 (a trademark of Times Microwave), and other 0.400″ / 10mm jacketed low-loss coaxial cables.

Please note this cable is very stiff, and intended for permanent installations. You will need appropriate cable support or clips.

Installation note: It’s critical that all outdoor connectors are taped with self-amalgamating tape (not electrical tape)! Water will seep through screw threads over time, and will permeate your cable and antenna via the exposed connectors, causing performance to mysteriously drop some days or weeks after installation.
