Messi and Paoloni UltraFlex 10 Coax Cable

Messi and Paoloni UltraFlex 10 Coax Cable is a highly flexible and top-performing 10.3mm (.400") coaxial cable, engineered to provide significantly better performance than RG213 while offering exceptional electromagnetic interference protection. This cable is entirely constructed of copper, ensuring superior signal integrity and a dramatic reduction in background noise for amateur radio and various communication applications.

UltraFlex 10's extraordinary flexibility makes it an ideal choice for installations requiring tight bends, such as with rotor antennas. It's designed to withstand dynamic movements, ensuring reliable operation in demanding environments.

The cable features a UV-resistant black PVC jacket (overall Ø 10.3mm ± 0.15 / .400") for robust outdoor use (note: PVC sheaths are not suitable for direct burial). The inner conductor is made of 7x1.0mm copper wires (overall Ø 2.9mm ± 0.15 / 0.114"), providing both excellent conductivity and the flexibility needed for demanding installations. The dielectric is a triple-layer, high-pressure physical injection foamed polyethylene (overall Ø 7.3mm ± 0.05 / 0.287"), which aids in its 83% velocity factor and low capacitance of 78 pF/m.

For outstanding electromagnetic interference protection and noise reduction, UltraFlex 10 employs a robust dual-layer shielding system:

• 100% Screening Copper Foil: The first screen, made of copper with an applied PE-layer, effectively prevents cracking due to short radius bends and provides a complete shield against interference.
• Reactive Braid: A 71% screening from 144 copper wires, produced on advanced 24-spool machines (compared to standard 16-spool), results in 50% more crossovers. This design grants exceptional Screening Attenuation (SA) and allows the braid to react like a spring to twisting and bending, further enhancing performance. This comprehensive shielding achieves a Screening Efficiency (SA) of >105 dB from 100-2000 MHz.

With an impedance of 50 Ohm ± 3 at 200Mhz and a robust maximum peak power handling of 12,000 Watts, UltraFlex 10 is capable of supporting high-power amateur radio transmissions. Its minimum bending radius is 80mm (3.15 in) for up to 15 bends and 40mm (1.57 in) for a single choke bend, offering significant adaptability during installation. The cable operates reliably across a wide temperature range from -40°C to +60°C (-40°F to +140°F).
