Messi & Paoloni Ultraflex 7 PE low loss coax cable
Many OMs have been waiting for this!
The new Ultraflex 7 PE from Messi & Paoloni is a double-shielded low-loss coaxial cable with a diameter of 7.3 mm. Thanks to the special PE (polyethylene) sheathing, UV-resistant, waterproof and designed for direct burial.
ULTRAFLEX 7 is without any doubt one of our BEST SELLERS around the world! It is a coaxial cable for the frequency range from DC to 8 GHz. This new product can be used in transmitting and receiving systems in wireless communication technology as well as in the entire field of commercial high-frequency technology and electronics.
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.
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.

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.
