Product information "Ultraflex 10 Competition Koaxialkabel"
Ultraflex 10 – High-Performance Coaxial Cable by Messi & Paoloni (Italy)
Ultraflex 10 is a high-performance coaxial cable from the renowned Italian manufacturer Messi & Paoloni. It has been specifically developed for demanding amateur radio operators and professional applications up to 12GHz. With outstanding attenuation performance, high flexibility, and maximum shielding of 105 dB, it is the perfect solution for both stationary and mobile RF installations.
The inner conductor of Ultraflex 10 consists of flexible copper strands (7 x 1 mm), the outer conductor is made of 100% overlapping copper foil and a copper braid with 144 wires. The copper foil is coated with PE on the inside. The outer jacket is made of elastic, UV-stabilized PVC.
Key Features:
-
Very low attenuation – ideal for long cable runs
Extremely flexible – perfect for rotator antennas, tight spaces, or mobile setups
-
Excellent shielding – effective protection against RF interference and common-mode currents
-
Connector-friendly – compatible with standard connectors (N, PL, SMA, BNC for 10.3 mm)
-
Made in Italy – top manufacturing quality by Messi & Paoloni
