M&P ULTRAFLEX 7 /.287" [7,3 mm/0,287 inches Cable] WRTC 2018 OFFICIAL CABLE! THE WORLD RADIO TEAM CHAMPIONSHIP IN GERMANY! http://www.wrtc2018.de/index.php/en/presse-2/pressemitteilungen-2/158-messi-paoloni-to-become-gold-sponsor-of-the-wrtc-2018 EXTRAORDINARY flexibility:  perfect matching with rotator operated antennas, obtained by means of a sophisticated full copper stranded inner conductor (19 wires instead of 7).New improved dielectric: outstanding attenuations up to 8 Ghz, even better than some solid core cables of the competition. Screening efficiency:  >105 dB (SA) and improved sturdiness reached by adding 24 more wires to the braid, for a total of 144 wires, (83% coverage+ 100% foil). This leads to a dramatic reduction of the background noise. Moreover the braiders used are 24 spools, instead of 16 spools, giving 50% MORE CROSSOVERS.Lightweight:  6,9 Kg/100 m instead of 13,8 Kg of our M&P-RG213/U, for a reduced stress of the “hanging and swinging" stretch of the cable in rotor operated antennas.Excellent Power Handling!The external PVC jacket is in black UV resistant PVC. This cable delivers exceptional mechanical features and electrical properties. Notwithstanding its small dimension (7,3 mm) its performances are so good to outperform RG 213 U (10,3 mm) and put into shade the competitor cables of the same diameter. M&P-ULTRAFLEX 7 is without any doubt one of our BEST SELLERS around the world!

Airborn 5 AIRBORNE 5 /.200" [5 mm / 0,197 inches Cable] WHY CHOOSE THIS CABLE?: Same dimensions of a RG 58 C/U (5mm) but at 50 MHz its attuenuation is 3,6 dB/100m better. Perfect for direct burial and totally waterproof thanks to the PE carbon-black tearproof sheath that allow different kind of outdoor uses. Weights 1,4 Kg less per 100m than RG 58: its incredible lightness will prove a great operational advantage and will ensure significant savings in shipping costs and "DXpedition". It's only 5mm of diameter but Airborne 5, made with tough aluminium magnesium alloy braid, boasts a superlative robustness and enviable resistance.

POTA-FLEX 7 Koaxkabel Das neue POTA-FLEX 7 Koaxkabel wurde von Messi&Paoloni speziell für Outdoor-Anwendungen wie POTA (Parks on the Air), SOTA, IOTA etc. entwickelt, bei denen extrem robuste und gut sichtbare Koaxkabel gefragt sind. Die gelbe und reflektirende Ummantelung des Koaxkabels ist gut sichtbar und bietet somit auch an belebten Plätzen wie Parks tc. einen optischen Schutz und reduziert die Stolpergefahr und unbeabsichtigtem "Hängenbleiben". Das leichte und flexible Pota-Flex 7 Koaxialkabel von Messi e Paoloni hat einen Außendurchmesser von 7,65 mm, den Innenleiter bilden 19 einzelne Kupferdrähte. Die Abschirmung besteht aus 3 Schichten: 2 x Geflecht aus Kupferdraht mit jeweils 144 Drähten, darunter Kupferfolie mit einer PE-Schicht, die das Dielektrikum umgibt. Dadurch wird nicht nur eine ideale HF-Abschirmung erreicht, sondern das Kabel auch vor mechanischer Beschädigung geschützt.. Das Dielektrikum ist geschäumt, dadurch wird eine im Verhältnis zum Durchmesser sehr geringe Dämpfung erreicht.

Stealth-Flex 7 — 50 Ω Tactical Coaxial Cable (Messi & Paoloni) Stealth-Flex 7 is a rugged, highly flexible 50 Ω coaxial cable with a matte, camouflaging outer jacket. Designed for invisible installations: it can be run discreetly along trees, fences or building edges — ideal for radio amateurs and preppers who value discretion and reliability. Why this cable is ideal for radio amateurs & preppers Invisible installation: matte, camouflaging outer jacket (military green) reduces visibility in woods, parks or around houses — perfect when antennas and feed lines should remain unobtrusive. Discretion + reliability: low reflections and strong shielding provide dependable operation even in sensitive situations. Rugged & flexible: built for frequent coiling, tight bend radius and a durable jacket surface — practical for bug-out bags, field boxes and mobile emergency radio kits. Low loss at typical lengths: on short to medium runs (e.g., 10–30 m) performance for transmit and receive remains very good — important for QRP/emergency communications. Versatile use: discreet permanent installation, temporary emergency links or as a tactical feed for mobile and outdoor installations. Conclusion The Stealth-Flex 7 from Messi & Paoloni is the right coax when you need discretion, toughness and good RF performance together. The matte, camouflaging outer jacket enables invisible installations — ideal for radio amateurs who want to hide feed lines and for prepper/emergency kits that must be compact, reliable and hard to detect.

The AIRBORNE 10 /.400″ by Messi & Paoloni is a state-of-the-art, high-end coaxial cable designed for radio amateurs, professional radio applications, and demanding RF installations. Engineered for maximum performance with minimal losses, this 10.3 mm coaxial cable sets benchmarks in its class—especially for outdoor use and long-term operation. Extremely Low Attenuation – Measurably Better One of its standout features is the exceptionally low signal attenuation: only 19 dB / 100 m at 2400 MHz, measured on a 10.3 mm coaxial cable. This results in higher field strength, improved reception quality, and greater efficiency—particularly at high frequencies and over long cable runs. Designed for Direct Burial & Outdoor Use The AIRBORNE 10 is completely waterproof and specifically designed for direct burial in the ground. Its rugged, tear-resistant PE outer jacket reliably protects against moisture, UV radiation, temperature fluctuations, and mechanical stress—ideal for permanent outdoor installations without additional protective conduits. Lightweight, Robust, and Superior Shielding Despite its 10.3 mm diameter, the AIRBORNE 10 is approximately 45% lighter than comparable 10 mm coaxial cables, making installation and routing significantly easier. The ultra-dense copper braid consisting of 192 strands provides excellent shielding effectiveness, substantially reducing background noise and interference—an obvious advantage for receive-critical locations and DX operation. Cable Selection Tip Coaxial cables with a solid center conductor—such as the AIRBORNE 10—are ideal for fixed installations, as they exhibit lower losses than cables with stranded conductors. 👉 For very tight bend radii or rotor-mounted antennas, we recommend the ULTRAFLEX 10, which is specifically designed for maximum flexibility. Typical Applications Amateur radio (HF, VHF, UHF, SHF) Outdoor antenna systems Repeater and base stations Direct-buried antenna feeder lines Professional radio and data links Technical Specifications – AIRBORNE 10 /.400″ Characteristic impedance: 50 Ω Outer diameter: 10.3 mm (.400″) Center conductor: solid conductor Dielectric: foamed Shielding: ultra-dense copper braid with 192 strands Shielding attenuation: > 105 dB Capacitance: approx. 74 pF/m Velocity factor: approx. 87% Minimum bend radius: approx. 65 mm Weight: approx. 7.1 kg / 100 m Temperature range: −45 °C to +70 °C Outer jacket: PE, UV-resistant, waterproof Attenuation Values (per 100 m cable length) 1.8 MHz: approx. 0.6 dB 14 MHz: approx. 1.3 dB 50 MHz: approx. 2.4 dB 100 MHz: approx. 3.5 dB 144 MHz: approx. 4.2 dB 400 MHz: approx. 7.2 dB 1296 MHz: approx. 13.6 dB 2400 MHz: approx. 19.2 dB 6000 MHz: approx. 32.8 dB 12 GHz: approx. 50.2 dB Maximum Power Rating (CW at 40 °C) 3.5 MHz: approx. 8,471 W 7 MHz: approx. 6,667 W 14 MHz: approx. 5,180 W 28 MHz: approx. 3,731 W 50 MHz: approx. 2,939 W 144 MHz: approx. 1,710 W 400 MHz: approx. 992 W 1000 MHz: approx. 610 W 2400 MHz: approx. 375 W Informationen gemäß Art. 19 GPSRHersteller: Messi&PaoloniHerstellername: Messi & Paoloni SrlHandelsname: Messi & PaoloniAdresse: Via Giovanni Conti 1 - 60131 ANCONA, ItalyE-Mail: web@messi.itWebseite: https://messi.it/Verantwortliche Person:Name: Messi & Paoloni SrlAdresse: Via Giovanni Conti 1 - 60131 ANCONA, ItalyE-Mail: web@messi.itWebseite: https://messi.it/
