Hummm, Iāll keep my temptation out of this idea
Anyway something strange Iāve got in my office another GW custom made, this one and a Lorawan sensor and when I send packet itās received by both GW but custom GW receive it with -75dBi and Lorix one with -86 dBi (my sensor is RN2483 with no Antenna)

is the antenna could be ānot pluggedā ?
Also new LoraWan devices (sodaq, lorix) notice says to put antenna before powering them to avoid damaging the device ? Is it new that devices with no antenna can damage electronic ?
