50ohm Coaxial Cable 78 78L 1-14 Flex

Key Features & Construction:

• Optimized for Low Loss:​ Larger diameters, such as 7/8″, 1-1/4″, and 1-5/8″, feature a high-performance foam polyethylene dielectric that significantly reduces signal attenuation over long runs, making them ideal for tower feeder applications.
• Superior Flexibility Option:​ The 1/2″ Superflex​ variant utilizes a specialized design with a more pliable dielectric and conductor, offering exceptional bend radius and ease of installation in tight spaces without compromising the electrical performance of standard 1/2″ cable.
• Robust Shielding:​ All cables employ a combination of a corrugated copper or aluminum outer conductor, which provides excellent shielding effectiveness, mechanical strength, and environmental sealing against moisture ingress.
• Durable Outer Jacket:​ The cables are typically sheathed in UV-stabilized, black polyethylene (PE) for superior outdoor durability and resistance to sunlight, extreme temperatures, and abrasion.
• High Power Handling:​ The larger conductor and dielectric diameters of the 7/8″ and above sizes allow for significantly higher average and peak power ratings compared to smaller cables like 1/2″, supporting high-power transmitters.

Primary Applications:

• Macro Cell Sites:​ As the main feeder line from the base station radio to the antenna.
• In-Building DAS:​ For distributing signal throughout large venues (standard 1/2″ and Superflex are common here).
• Broadcast FM/TV Transmitters:​ For high-power transmission lines.
• Public Safety and Land Mobile Radio (LMR) Systems:​ Connecting repeaters to high-gain antennas.
• Microwave and Satellite Communication Links.
