Temporary ham HF antenna

[dtvmcdonald]

I'm looking for web sites that discuss making your own HF (40-10 meters) antenna system for apartment dwellers.

I already have one for myself which I designed and built. It is on all bands an off-center fed slightly sloped dipole. It uses different lengths for each band,
such that one adds a piece on the est end of the 10 meter dipole for 12m, then adds a piece on the east end for 15 meters, then adds to the 12m west side a second piece for 17 meters, etc. Changing bands takes about 5-7 minutes.

I have not seen any descriptions of such an adjustable system setup. I'm making a presentation describing my antenna and would like to see if others have described such a system before.

Mine works very well with SWR of better than 1:1.6 on all bands and results I would expect from the peak height (21 feet), i.e. it burns clouds on 40 meters.
