LTE-M antenna doesn't fit into the IP67 Case



  • I've just received my pledge, started more detail looking at the components and found 1st issue.

    During the campaign according to KS Update #4 offer, I've increased my pledge with IP67 Case and according to the info (quote below - bolded) I was convinced that I would be able to put the antenna inside the case.

    "(...)We have been busy and managed to put together a deal for a superb quality IP67 case which can safely house your Pytrack or Pysense with a FiPy and a battery. The case will also be supplied with an IP67 cable / connector for the external LoRa/Sigfox antenna. For those whom have purchase the LTE-M antenna, then you would simply attach it inside the case.(...)"

    Any ideas how can I do that?

  • @rskoniec You can bend the antenna to make it fit. Besides that, you may use a different antenna, as long as it has about 50 Ohm impedance at the frequency you use and the matching connector. It may have a slightly different gain. But the way the supplied antenna could be installed in the package, any gain figure is anyhow questionable.
    P.S.: if you look for "lte pcb antenna" at aliexpress.com, you will get quite a selection, larger and smaller ones.



  • @rskoniec I wonder what antenna you ended up with? I have been looking for significantly smaller antenna than Pycom suggests (WIESON) in order to produce way smaller packed device...



  • I found that on the LTE-M Antenna Kit page presented antenna is quite different from mine.
