This little crap #lorawan beacon with 3 cm antenna and powered by a single 18650 cell was heard from Pen-y-Fan peaks (next to the green "B...n" icon in the middle, stands for Brecon) at the coast of Irish Sea (far to the left).

After checking on a map I got... distance of 80 km! 😮

For reference, this was SF12BW125 so the slowest LoRaWAN rate where ~50 bytes took 1.4 sec to transmit, but this apparently gives pretty impressive distance.
