The prototype worked well enough that I'll proceed on to another iteration. Leaning it out with two legs held up by the radial wire worked well, and the little knobs on the top of the spool to hold the wire in place work fine. I'll made them a touch larger to be more robust, but the concept works.I want to be able to fit 12m of wire on the spool, because I want radials that work well as flat radials on 40m, which might take up to 28%λ instead of the nominal ¼λ which would be appropriate in the "discone" setup with 45° radials. However, with this wire, 8m barely fits on this spool. So I need to add a generous allowance for more wire.I need a handle for the hub at the bottom so that I can wind it up with the legs removed. It's unwieldy with two 6' long fiberglass stakes.According to DJØIP, 1 elevated, tuned radial is roughly equivalent to 8 ground radials. Two of these should give me the performance of 16 ground radials. According to his table, I can expect 3.76dB gain over my usual 4 radials on the ground, or even more if I'm using a shortened antenna.With these just leaning, if someone inadvertently walks into my bright pink wire, they'll probably just knock over the leaning posts, which is unlikely to cause a big problem. I'll probably use bullet connectors for the other end of the wire so that they can pop out and not knock the antenna over.
