Hi, Bob:
I'm good, really too good ;o) at mis-writing, dag nab it, and I forgot that 15M wasn't a ham band when Lattin was working on the patent for this kluge. IIRC, the design was for 4, not 5, bands: 10-20-40-80M, with single wires at D. Accepting that, and re-writing just the C-stub function ... SNIP If the dimensions are added up, the overall physical length approaches that of an 80M dipole. "Loading-effect" of the "fat-wire" dipole could be helped along if needed on 80M by additional wire length past A. The A-stubs reduce the electrical lengths each side to overall 40M-dipole-size. Ditto B-stubs on 20M. ******rewrite*** Ditto C-stubs on 10M. ******rewrite****** Changing the D-lengths to single wires, or shorting both inner ends, completes the 10M-dipole section. SNIP ... should do it. Imagine adding 60-30-17-15-12M to this kluge. Lattin's patent was 2535298. 73, Dave, N3HE |
