This isn't what others are saying. Most die hard 2.4 users from P4 and P3P days assumed also with conventional wisdom that 2.4 would work better for distance, but not so with
P4P for some strange reason. Most folks attribute it to the lack of 5.8 band interference, and the less capability of any interference from inside a building has a harder time going through walls, into drone territory. As long as you have LOS connection (no trees or buildings in between you and the drone), 5.8 will go 5 miles, even in populated areas. Being elevated on a hill and flying below helps a lot with distance, but 5.8 is the bees knees for distance.
