3/8" corrugated coaxial cable, with its 50 ohm impedance, 0-3GHz frequency band, and low loss of 0.1dB per meter, is an ideal choice for base station antennas and indoor distribution systems. The copper tube conductor and foamed polyethylene insulation layer ensure signal stability, while the 10-times diameter bending design balances strength and flexibility. Such cables typically feature moisture resistance, UV protection, and other characteristics. When used outdoors, the sheath material is added with anti-aging agents. Some models also support flame retardant requirements, meeting relevant safety standards.

There is a wide variety of 3/8" coaxial cables available. When selecting, users should consider factors such as shielding performance, impedance matching, and environmental adaptability based on their specific needs. These cables are widely used in the following fields:
Communication base stations: used to connect antennas and RF equipment to ensure stable signal transmission;
Radio and television: used as signal transmission lines to reduce signal loss and interference;
Industrial automation: used to transmit control signals or data in factory equipment, where high temperature resistance and anti-interference capability are key;
Security monitoring: used for video signal transmission to ensure clear and stable images.
