The performance and extreme flexibility of Hyperflex 5 with a transparent outer jacket that leaves the high-quality braid visible.
Choose your cable length and connector combination and let us build the lead for you.
Messi & Paoloni Hyperflex 5 Crystal combines the compact dimensions, low loss and extreme flexibility of standard Hyperflex 5 with a distinctive transparent outer jacket that leaves the cable braid visible.
At just 5.4mm overall diameter, it is a particularly useful cable for portable installations, patch leads, mobile applications and rotator-fed antennas where a larger coaxial cable would be unnecessarily bulky.
Internally, Hyperflex 5 Crystal uses the same high-performance construction as standard Hyperflex 5, including a 19-strand copper centre conductor, physically foamed polyethylene dielectric, full foil screen and 120-wire reactive copper braid.
Crystal-clear outer sheath leaves the high-quality copper braid visible for a distinctive finish.
Compact dimensions make it ideal where a larger low-loss cable would be too bulky.
High velocity ratio from its physically foamed polyethylene dielectric.
19-strand centre conductor and reactive braid make it particularly suited to repeated movement and tight installations.
Hyperflex 5 Performance, Crystal Finish
Hyperflex 5 Crystal is primarily about giving the proven Hyperflex 5 construction a different appearance. Beneath the transparent jacket, the electrical design remains the same as the standard black version.
The 120-wire copper braid is manufactured using a 24-spool braiding process, providing more braid crossovers than a conventional 16-spool construction. This helps the cable remain highly flexible while maintaining excellent screening.
With an 87% velocity factor and screening efficiency greater than 105dB between 100MHz and 2000MHz, Hyperflex 5 Crystal provides the same strong RF performance as standard Hyperflex 5.
Where Hyperflex 5 Crystal Works Best
Compact diameter, excellent flexibility and its distinctive clear finish make it particularly attractive for visible shack interconnections.
Lightweight and easy to coil for transport, making it well suited to portable amateur radio operation.
Extreme flexibility makes the cable useful around moving antenna systems and rotator loops.
M&P Cable Length Guidance
As Hyperflex 5 Crystal uses the same RF construction as standard Hyperflex 5, the same cable length guidance applies. These figures are recommendations for choosing the most appropriate cable size rather than absolute operating limits.
| Example Frequency | Excellent | Good | M&P Guidance |
|---|---|---|---|
| 14MHz | Up to 50m | Up to 75m | Consider larger coax above 75m |
| 28MHz | Up to 35m | Up to 50m | Consider larger coax above 50m |
| 50MHz | Up to 28m | Up to 40m | Consider larger coax above 40m |
| 144MHz | Up to 10m | Up to 20m | M&P recommends 10.3mm coax above 20m |
| 430MHz | - | Up to 5m | M&P recommends larger coax for longer runs |
| 1296MHz | - | Up to 3m | Use larger coax for longer runs |
