Davis RF DRF-400 – Low-Loss 50 Ohm Coax Cable (Data Sheet)

DRF-400 by Davis RF is a low-loss, high-performance 50 Ohm coaxial cable engineered to match the electrical performance of LMR-400, with the added advantage of rugged outdoor durability and flexibility. Designed for use in HF, VHF, UHF, and even SHF systems, DRF-400 is ideal for both base station and mobile feedline runs.

Why Choose DRF-400 Over LMR-400?

  • ✅ Equivalent Electrical Specs – Comparable attenuation and VSWR across the frequency range
  • ✅ Enhanced Jacket Durability – Rugged polyethylene outer jacket is superior for outdoor use
  • ✅ Flexible & Installer-Friendly – Easier to handle than solid-core alternatives
  • ✅ High Shielding Effectiveness – 100% coverage foil plus 90% tinned copper braid for strong RFI protection

Ideal Applications

  • ✅ Base station coax runs from radio to antenna
  • ✅ HF through 2.4 GHz amateur and commercial systems
  • ✅ Low-loss jumpers and interconnects in repeaters and stations
  • ✅ Environments requiring superior weather and UV resistance

Specifications (Compared to LMR-400)

  • ✅ Inner Conductor: Solid bare copper (0.108 in / 2.74 mm diameter)
  • ✅ Dielectric: Foam polyethylene (0.285 in / 7.24 mm diameter)
  • ✅ Shielding: Bonded aluminum tape and 90% tinned copper braid for >90 dB isolation
  • ✅ Jacket: UV-resistant black polyethylene (0.405 in outer diameter)
  • ✅ Weight: 0.068 lb/ft (0.10 kg/m)

Davis RF DRF-400 is the preferred coax for those seeking LMR-400 performance with enhanced jacket toughness and stranded-core flexibility. Made in the USA and available in bulk spools or cut-to-length options for any RF system.
