Pros & Cons

Pros

  • ✓ RG316 coax with pure copper inner conductor for low-loss signal transfer
  • ✓ SMA male to SMA female bulkhead mount ends fit panel-through enclosure installs
  • ✓ 4FT length routes an antenna away from the radio without a separate adapter
  • ✓ 50 Ohm impedance matches SDR, ADS-B, 4G LTE and GPS antenna systems
  • ✓ Two cables per pack at 14.99, so a second radio or spare costs nothing extra

Cons

  • ✗ Bulkhead end needs a drilled panel hole, so it is awkward on sealed cases
  • ✗ RG316 is thin coax and loses more per foot than RG58 or LMR on long runs
  • ✗ 4FT is the only length listed, with no shorter or longer option in the pack
  • ✗ Heat-shrink strain relief adds bulk right at the connector in tight bays
