External Wifi Antenna Experiment and Results



  • Here's some information about using an external IPX antenna. I am using a junk antenna I got off an old router and had some good results. I'd venture to guess I'd get better results with a longer antenna mounted vertically rather than glued to the bottom.

    I got a decent speed increase using speedtest-cli after adding the external antenna.

    Before external antenna.

  • @Paul-Jobson When I was testing several external antennas on Omega2 I had best results by cutting the connection to the on-board chip antenna - with RF two in-series antennas is not better than one!
