Soldering a coax cable to RFM69



  • Hi,

    What do you think about this?
    Wanted to increase the GW range so trying to use a bigger 433MHz antenna.
    Would this be the correct way to make it?

    @joaoabs yes that looks fine.

    Keep the non-shielded part of the cable as short as possible, but you’ve already done a great job so I think it would be hard to make it shorter.

    Personally I would probably have chosen to solder a pigtail (with sma contact) to the rfm module, to make it possible to switch to a different antenna/coax cable without soldering. But each connector introduces loss, so soldering might be the best choice.
