Further thoughts....

In order to be able to both release and then fold up the
antenna, a mechanism based on two tendons, not too
dissimilar to the human knee and elbow joints would be
required.

Consider the flexing effect of each of your fingers - one
tendon at the back and one at the front.

And in order to maintain good RF contact across the joint,
perhaps the use of braid recovered from coax cable?

Could we conceive of an antenna, even possible an HF beam, that
folds away into a single rod-like structure when not in use?

Be nice to see the effect the weather would have on the braid though
after a few months - turn it nice and black.

Another one of Gareth's not so good ideas.

Gareth, has ANYTHING of yours even worked?

do i have this read right?

you're planning to go down to the cemetry, dig up the dead bodies and chop
off their legs and arms so you can use their two tendons for raising and
lowering your mast?


great stuff beanie, you've surpassed yourself this time!
