Hi, all concerned:

www.g3ycc.karoo.net/lattin.html

is the corrected url.

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.

Ditto C-stubs on 15M.

Changing the D-lengths to single wires, or shorting both inner ends,
completes the 10M-dipole section.

Editorial comments:

The feed shown is "incorrect". Stubs at D are not needed, unless one wishes
to add higher-frequency capability. Single wires are sufficient for the 10M
portions of the dipole.

This Lattin antenna is not easily constructed or tuned, and it reminds me of
something from the category of solutions running around looking for
problems.

The current amateur application that I can think of which is done "properly"
is the KLM h-f tribander. The stubs are of open-construction, and the first
stubs, at the outside end the 10M portions of the antenna elements, can be
seen easily, even in pictures.
