Being an amateur radio operator, I frequently build antennas of wire only.  These need to be suspended rather high off the ground.  I can take my Phantom 4 and drag a fishing line with a lead weight attached, over a treetop and land. The lead weight can be placed on the line to prevent contact with the props.    From this fishing line, I can then pull the heavier wire antenna over the tree as needed.  Also, it is easy to determine line of sight from your antenna site simply by flying the drone to the location of the antenna and using the camera to record the view to the target antenna.  What other uses can be thought up?

Tieing a line to a drone to drape over a tree is very risky. what if the line gets tangled in a branch, You just lost your drone.

Not if you fly it high enough and with enough line to clear the tree before you start to land.  Simply pay out enough line to clear the tree.

I found a better way.  I taped a short wooden dowel to the landing strutts so it stuck out about 6 inches to the front.  I then made a loop in the end of the fishing line, or parachute cord and had a weight attached to the short end.  I looped the line over this dowel and flew the drone dragging the semi slack line over the tree and about double the height.  Then pulled it farther over in the clear and simply yawed the drone so it turned 180 degrees and the semi slack line pulled it off the dowel allowing it to fall straight down.  I used this 5 or 6 times to hand a 160 meter double bazooka on my tower side arm at 110 feet.  Just be sure you don't do what I did first attempt and drop the weight just over the target.  Mine fell down through the tower and lodged, requiring a rather long climb to retrieve it.

Glad to see a fellow Ham here on the forum. I have used my drone many times to string my antennas. It works great .
