Topband: Drones for antenna installation?

[David G4FTC]

The one thing that scares me with the tennis ball launcher is the risk of the plastic air reservoir exploding - probably not a problem with new pipe but as the pipe ages I would expect the pipe to become brittle and that brittleness may not be easy to detect until it is pressurised.

The sling-shots do have the problem of the rubber tubes perishing - but a visual check will easily detect this.
