Messi and Paoloni HyperFlex 13 Coax Cable: The Apex of Flexible Performance for Ambitious Installations
Messi and Paoloni HyperFlex 13 Coax Cable stands as the pinnacle of M&P's coaxial cable offerings, a must-have for the most demanding and ambitious amateur radio installations. This half-inch (12.7mm / .500") coaxial cable delivers excellent performance with the lowest possible signal loss, even at the highest frequencies and over long distances, rivaling the attenuation of stiffer and bulkier 15mm (.500") competitor cables while being lighter, more flexible, and more manageable.
Despite its substantial size, HyperFlex 13 is engineered for exceptional flexibility, designed to withstand tight bendings and the continuous movement associated with rotor antennas. Its 37-wire central conductor (37x0.56mm copper wires, overall Ø 3.8mm ± 0.15) is a unique feature, offering superior flexibility and electrical characteristics compared to cables with fewer strands.
HyperFlex 13 boasts a UV-resistant black PVC jacket (overall Ø 12.7mm ± 0.15) for durability in outdoor environments (note: PVC sheaths are not suitable for direct burial). The dielectric is a triple-layer, high-pressure physical injection foamed polyethylene (overall Ø 9.9mm ± 0.05), contributing to its impressive 86% velocity factor and low capacitance of 75 pF/m.
Superior shielding is a hallmark of HyperFlex 13. It features a 100% screening copper foil (with an applied PE-layer to prevent cracking) and a robust reactive braid with 82% screening from 240 copper clad aluminum wires. This braid is made with advanced 24-spool machines, ensuring 50% more crossovers for exceptional Screening Attenuation (SA) and a spring-like reaction to twisting and bending. This dual-layer shielding system results in a Screening Efficiency (SA) of >105 dB from 100-2000 MHz, earning it a Screening Class A++.
With an impedance of 50 Ohm ± 3 at 200Mhz and an extraordinary maximum peak power handling of 20,000 Watts, HyperFlex 13 is built to support the most powerful amateur radio setups. Its minimum bending radius is 140mm for up to 15 bends and 100mm for a single choke bend, providing remarkable flexibility for a cable of its size. The cable operates reliably across a temperature range from -40°C to +60°C (-40°F to +140°F).
