Unclear on the specific specs of the drones Hezbollah uses, but the distance seems to be in the ballpark of 3-20 miles.
The Electronic Intifada reported that the drones are built from components stripped from other common commodities^[https://invidious.nerdvpn.de/watch?v=hY25JlG7EY8&t=938], meaning the drone supply chain cannot be targeted by sanctions while also allowing the drones to be customized to the mission. They also report that the fibre optics enable zero-latency communication between the drones and their operators, and in addition the drones can operate low to the ground^[so low to be in the grass https://invidious.nerdvpn.de/watch?v=504BsSnX5Uc&t=1314] and in hilly/city terrain that might otherwise naturally block radio frequencies^[https://invidious.nerdvpn.de/504BsSnX5Uc?t=2042]
