P3 500 seamless Trunk cable

The 75 Ohm ½ inch seamless aluminum hardline cable is the workhorse of professional RF distribution networks. Its robust, low-loss design ensures signal integrity over very long distances in demanding environments, making it a critical component for cable operators, telecommunications companies, and broadcasters. Its installation is a specialized task, far beyond typical consumer-grade cable work. Features  Impedance: Precisely 75 ohms, the standard for video and data broadcast systems.  Center Conductor: A solid copper-clad aluminum (CCA) or solid copper wire, held precisely in place. Dielectric: Primarily uses a cellular polyethylene foam or air dielectric (held in place by periodic spacers). This "semi-air" dielectric provides excellent electrical properties with very low signal loss. Outer Conductor: The defining feature is a seamless, corrugated aluminum tube. The corrugations provide exceptional mechanical strength, flexibility for bending (during installation), and resistance to crushing. Jacket: A tough, black polyethylene (PE) jacket protects the aluminum tube from environmental damage, moisture, and UV radiation. Applications: The main advantage of ½" hardline cable is its extremely low signal loss (attenuation), even at very high frequencies. This makes it indispensable for: • Cable Television (CATV) / HFC Networks: Serving as the main trunk and feeder lines running along utility poles or through underground conduits, connecting the headend to distribution nodes. • Cell Site (Mobile Network) Infrastructure: Connecting baseband units (BBUs) to remote radio heads (RRUs) atop cell towers. • Broadcast Antenna Feeders: Used by FM radio and television broadcast stations to connect their high-power transmitters to the antenna on the tower. • Superior Shielding: Provides virtually complete immunity to external electromagnetic interference (EMI) and minimizes RF leakage.
