  • Helps boost signal strength and speed of your 4G LTE device

  • The Optus B800 mobile broadband router has two antenna sockets - use the left connector when connecting only one antenna

  • We recommend the use of dual antennas when on the 4G network

Why use an external antenna?


  • Next time you're out-and-about look around you - every day thousands of Australians use external antennas to enjoy fast, uninterrupted wireless broadband internet

  • If you're in a rural, hilly, low signal area, or you can't get a good signal indoors, there's no need to tear your hair out over slow mobile broadband crashing or dropping out half way, when an external antenna is often all you need.


What does a patch lead do?


  • Most antenna cables terminate with a standard connection, most commonly a female 'FME' connector

  • To plug an antenna into your phone or wireless modem, you need a short cable that acts as a conversion from the FME connector to the device-specific connector that will plug into the antenna port on your device.
