LMR-400 Low Loss Coax Cable (50ft, SMA-M to TS-9)

4.4

LMR-400 is the coax cable standard for fixed wireless installs. Cheaper RG-58 or RG-174 cables have significantly more loss at 5G frequencies — you’ll lose measurable signal on any run over 15 feet. LMR-400 keeps losses minimal even at 50+ feet.

Double-check your modem’s connector type before ordering: most USB hotspots use TS-9, most panel antennas terminate in N-male or SMA-male. You may need an adapter.

Pros
  • Very low loss — critical for long runs between antenna and modem
  • Outdoor-rated UV jacket
  • SMA male to TS-9 works with most USB modems and hotspots
  • 50ft standard; bundles available for different runs
Cons
  • Stiff — needs large bend radius (1.5 inch minimum)
  • Bulky connectors don't fit through small wall openings
  • Must match connector types to your modem's antenna ports
