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.

Specific attenuation examples

• 1.8 MHz — 10 m: ~0.11 dB · 20 m: ~0.22 dB · 30 m: ~0.33 dB

• 3.5 MHz — 10 m: ~0.13 dB · 20 m: ~0.26 dB · 30 m: ~0.39 dB

• 7 MHz — 10 m: ~0.17 dB · 20 m: ~0.34 dB · 30 m: ~0.51 dB

• 14 MHz — 10 m: ~0.22 dB · 20 m: ~0.44 dB · 30 m: ~0.66 dB

• 28 MHz — 10 m: ~0.30 dB · 20 m: ~0.60 dB · 30 m: ~0.90 dB

• 50 MHz — 10 m: ~0.40 dB · 20 m: ~0.80 dB · 30 m: ~1.20 dB

• 144 MHz — 10 m: ~0.69 dB · 20 m: ~1.38 dB · 30 m: ~2.07 dB

• 430 MHz — 10 m: ~1.23 dB · 20 m: ~2.46 dB · 30 m: ~3.69 dB

For many amateur and emergency radio scenarios these losses at common lengths are negligible — especially when discretion is more important than minimal loss.
