Some of us have encountered the wrath of our local planning
committees when erecting antennae that seemed reasonable to us,
but perhaps unreasonable to SFB neighbours.
Could we conceive of an antenna, even possible an HF beam, that
folds away into a single rod-like structure when not in use?
I have in mind the way in which quite elaborate antennae and solar
cells unfold from a satellite once it reaches orbit.
Such an antenna, if it were to be deployed only during the hours
of darkness, might also serve the needs of those who are obliged
to use stealth antennae due to restrictive covenants on the buildings
used as their shacks!


Simple Gareth, buy a scam mast, less than 12 foot tall so no planning
problems. even Liz might approve...
Or you could try an underground dipole, perfect for inter G on the lower
bands, No RFI and a nice quiet receive. Even in your 70 foot garden you
should be able to fit an 80M dipole in a straight line.


There is also a commercial 'roll out' antenna about. I'm sure someone
competent with a model engineering workshop could emulate it.

I've used the flat metal tape from a retractable tape measure in the past
for antenna elements- this could be the basis of a 'roll out' design.
