According to the book, Sideline Beekeeping for Alpaca and Ratite Farmers, Max distance they go is 105.84 meters. Average distance is 20.695m. Recommended distance to put a bait hive is 9.065m from your beeyard with a swarm lure in it and you will catch swarms from your own bees and maybe from other local hives. Just make sure that the bait hive is a minimum of 1.817m above the ground and a maximum of 3.126m above the ground which is the height that a person of your stature should be able to reach from a 1.22m or 1.83m ladder.
