But in your design the antenna wire will be carrying serious tension loads in addition to its own weight, and you would need aerial components suitably rated for this. -- from Aero Spike |

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! I know the ideal 'antenna' for you, Beanie, it's called a 'dummy load', affordable even on benefits from your local CB shop. You could also try replacing your broadband modem with a dummy load and leave Usenet in peace. ....(_!_)... |

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? "Airy R. Bean" wrote in message ...

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! dr. x 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. |
