Good presentation. No stranger to asking a stupid question, but I am thinking of the 10 meter slinky I used to run in my attic years ago. I had it strung from one end of my apartment attic to the other over some chord; less than 30 ft. I don’t recall how I tuned it or how long the actual straightened slinky would have been. Not sure it was that sophisticated. I think I probably used two slinkies on each side. My log shows the SWR was great. I wonder how this would be if I had turned this slinky dipole vertically. Probably would yield a high Q, for sure, but I wonder how far you can carry the concept of coiling a dipole to shorten its length, and get away with it.
