43dBm is still pretty powerful considering 100mw is enough for an RF signal in open space to travel 20-30 miles. It was a guess though so its allowed to be wildly inaccurate
What RF kit do you have with that performance? 4G mobiles have a maximum EIRP of 24 dBM (0.25W) and they don’t have half that range even with the extremely complicated rake receiver arrays on the base stations.
My 5W VHF Motorola walkie-talkies manage 2 miles direct line of sight on a good day.
