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

Messi & Paoloni Ultraflex 10 Low-Loss Coaxial Cable – Assembled The Ultraflex 10 Competition coaxial cable is professionally assembled by us and can be supplied with connector types of your choice. All connectors are expertly installed in-house and subsequently tested. The available cable lengths are based on our many years of experience and the most commonly requested sizes. Of course, we are happy to manufacture custom lengths or alternative connector configurations according to your requirements. Simply get in touch with us—we’ll be glad to advise you. The Innovation of Flexibility in 10 mm Coaxial Cables from Messi & Paoloni The Ultraflex 10 Competition low-loss coaxial cable from Messi & Paoloni is suitable for frequencies of up to 8 GHz. This RF cable is highly flexible and designed for use in HF, VHF, UHF, and even SHF applications. Ultraflex 10 is manufactured with a 7-strand center conductor, which enables an unprecedented level of flexibility for a cable with a 10.3 mm diameter. High Performance for Almost Every RF Application Ultraflex 10 is a coaxial cable suitable for most radio and RF applications. It is extremely flexible, features low attenuation, and offers excellent protection against interference thanks to its double shielding (foil and tight copper braid) with a shielding effectiveness of 105 dB. A carefully manufactured braid produced using 24 carriers surrounds the plastic- and copper-coated aluminum foil. The optical coverage is 71%, ensuring reliable shielding performance. Key Features Very low attenuation – ideal for long cable runs Extremely flexible – perfect for rotor antennas, tight installations, and mobile applications Excellent shielding – reliable protection against RF interference and common-mode currents Connector-friendly – compatible with common connectors (N, PL, SMA, BNC for 10.3 mm cables) Made in Italy – highest manufacturing quality by Messi & Paoloni Compared to RG58U The significant differences compared to RG58U are described in detail in a separate article, including many real-world examples.

N-Stecker 10mm Messi & Paoloni
N-Stecker 10mm Messi & Paoloni
Variante: Einzeln

Messi & Paoloni N-Stecker für 10mm Koaxkabel Dieser hochwertige N-Stecker von Messi & Paoloni ist für die Koaxkabeltypen: Ultraflex 10, Hyperflex 10, Airborn 10, Ecoflex10, RG-213, H2000 geeignet. Der Löt-N-Stecker kommt mit Dichtungsring, PTFE-Dielektrikum und vergoldetem Mittelstift zu Ihnen. Die zwei diamagnetische Mittelstifte sind lötbar und lassen sich auf viele 10,3 mm-Kabel montieren. Die Mittelstifte sind mit verschieden großen Lötöffnungen versehen. Die zwei mitgelieferten PTFE-Scheiben ermöglichen eine einfache Installation des Steckers. Die PTFE-Scheiben und eine ringförmige Verdickung auf dem Mittelkontakt verhindern, dass das Kabel bei mechanischer Belastung aus der festgelegten Position gezogen werden kann. Kompressionsdesign mit doppelter Dichtung, die einen besseren Schutz gegen das Eindringen von Wasser, Feuchtigkeit und Kondenswasser gewährleistet. Einfache Installation und Lötanleitung im Paket enthalten (kein Lötgeflecht erforderlich). Drastische Unterdrückung des Hintergrundrauschens, Verbesserung der Schirmdämpfung und der Einfügungsverluste. Die Oberflächen sind mit einer speziellen Legierung namens Smart3-Alloy® behandelt: Sie ist korrosionsbeständig und antiallergisch. Der neu konzipierte Stift verhindert einen Zinnüberschuss und die daraus resultierende Erwärmung, die das Dielektrikum beschädigt und zu einer unkontrollierbaren Veränderung der elektrischen Eigenschaften Ihres Kabels führt.
