The distance of a multirotor is mostly decided by its radio connection quality – the invisible link between the aircraft and the transmitter that functions the same as radios or other remote control vehicles. Most drones employ a 2.4 GHz radio frequency, that can offer you around 1500 m in the most excellent conditions. Low frequencies, as 1.2 GHz, offer you better distance but are unlawful in many states since those are the exact frequencies used with commercial aircraft.
