Drones should work real good for deploying a line over the top of a tree.
However, in many yards (mine included) there can be serious issues with
going over the tops of trees as opposed to simply going over a high limb.
In my case, I have three dipole-type antennas deployed in a grove of tall
Pine trees. An 80M OCF is at 81' feed point and about 70' at the ends. Two
40/20 fan dipoles are at about 78' and 71' and the ends are at about 65'-70'
in other Pine trees. My dipoles are supported in the center and at the
ends. No hurricane has ever taken them down. There is a lot of resilience
with three supports and not being in the tops of the trees.
I used a tennis ball launcher to get the lines into the proper positions.
Today I went out and looked at the situation and imagined a drone putting
the lines into the proper positions. I don't think a drone could do it
except maybe for two of the ropes. The end ropes, in particular, are pretty
well buried up in a lot of limbs.
Pine trees, in particular, swing a lot up at the tops but they swing a whole
lot less down 20' or 30' below the tops. Going over the top of a Pine tree
seems like asking for a whole lot of trouble down the line.

Hi Don,
Take a look at this video. EA1DR sent it to me recently as we´re planning to
deploy an inverted L for 160 over some high trees in their property.

Hope this help. 73s

I've seen past posts about the use of drones for antenna work.
While interesting reads at the time, I wasn't there, so didn't bother to
file 'em away.
Now I'm interested. Particularly, how were you able to 'release wires'
over trees etc (the methods used to drop those wires)? Did the drone
have a quick release option or accessory that made it usable for the task.
If your drone purchase was recent. I'd also be interested in
recommendation of brands and models you found best suited for this kind
of task (among its normal uses), whether it was the one you purchased or
not.
