50ohm Coaxial Cable 78S 1-14 1-58 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.
