USB CABLES for WiFi Adapters are a much better choice than standard coax Antenna Cables because  antenna cables (coax) lose a lot of signal-strength.  USB cables lose little signal: Hardly any, in comparison.

Antenna cables – the type that go between a WiFi device and an antenna – are “coaxial” type cables:  These coaxial cables lose a significant amount of the WiFi signal in every meter of coax cable (1/2 to 1 dBi per meter is typical).

SOLUTION for loss of signal in antenna cable

Other USB Extension cables:

WATERPROOF connections:  To waterproof USB connections that might be exposed to rain, sea mist, etc: 

DETAILS:

  • Active” USB cables lose only about 2.1% of signal per five meters – and so provides much more signal strength from your USB wireless adapter, compared to using coax antenna cables.

Other benefits

  • USB cables are simple:  Not confusing like antenna cables’ confusing connectors.
  • USB extension cables have many alternative, practical uses if you later do not need it for your WiFi adapter.

POWER to USB device:   Transmitters need power. More power results in greater range. It is critical that the transceiver receives enough power to do its job. Some (older) laptops do not provide enough power via a (single) USB port. Drawing power from multiple ports can be a solution. Also using high quality USB cables and keeping cable runs short helps. Alternative, one needs to provide an external source of power.
