XRDS -RF CB Coax Cable 50FT

Pros & Cons

Pros

  • ✓ 50 ft RG8X run with enough length for mast, roof or marine antenna routing
  • ✓ Pure copper center conductor for low-loss RF signal transfer
  • ✓ Double shielding (braid + foil) helps keep interference out
  • ✓ Nickel-plated PL-259 and FME connectors resist corrosion outdoors
  • ✓ Includes FME male to PL-259 adapter, so you can use two connector setups

Cons

  • ✗ Listing gives no attenuation spec (dB per 100 ft) to compare against other coax
  • ✗ No maximum power rating stated, so check it before running a high-watt amp
  • ✗ RG8X is thinner than full-size RG-8 or RG-213, with more loss on long runs
  • ✗ 50 ft is more than most vehicle installs need, so you may have slack to coil up
