This current interest (and privacy furore) about drones set me thinking,
what an interesting way to elevate a TopBand vertical, but being a temporary
structure, not breaching any planning permission (Brit) or zonal (Yank)
restrictions.
However the height of a 1/4 vertical would be such that it may fall
under the regulations of the CAA (UK) and the FAA (US) depending on
the location.
Under 60m (~200') does not require any permission in the UK.

I didn't say anything about "permission", I said regulations, and you
may want to check the fine print, e.g. the FAA has language about 200
feet AGL within 3 nautical miles of an airport, which is why I said
"depending on the location".
And if one is thinking about a balloon or kite antenna, the FAA also
has language about within 5 miles of an airport and visibily of less
than 3 miles.
I vaguely recall reading about rules for antenna height near airports.

I am sure the CAA has similar fine print.
