Battery life for most drone flights will typically limit your flight time to
20-25 minutes or less ...... so a drone is likely to be helpful for lifting
a weighted line into the air and stratically dropping it over a support
(tree branch, etc) ... which will then allow that line to be used to pull
the antenna/rope over the same branch ... but it is not practical for
continuous support like a balloon will give you... and: even though a
drone can easily lift a monofilimant line with a small weight and then use a
remote release to drop it .... it's very doubtful that it will be able to
support the weight of a long wire antenna

Subject: Re: [CQ-Contest] Drones
I see there's expertise here using drones so I'll ask a related question.
For the last few years I've been using balloons to lift vertical antennas on
160 and 80. (You can see a picture on my qrz page.) It works pretty well as
long as the wind is below ~12 mph. Above that the antenna rotates far enough
from vertical that the different coupling to ground makes it unusable.
I've been thinking that a tethered drone might do better in the wind. I've
tried small, cheap (< $100) drones and they're almost as bad as balloons.
The more expensive drones claim better wind resistance. It doesn't have to
hold position too precisely; 10 to 20 degrees from vertical should be OK.
Any thoughts?
