[Antennas] Shortened Antennas

[Bob Wilder]

Need help from some of the experts on the list.  I know if I wind 1/2 wave of
wire as a helical element I should realize about a 12-15 ohm impedance and 
the element
would appear as if it was electrically 1/4 wave.  If I take two of these 
elements
and feed between them I would have a dipole.  Now here is where I need 
help.  If I wind
each of the elements as "electrical" 5/8 waves and feed the two elements at 
the center
it seems to me this would "act" like two 5/8 waves as a two element 
colinear.  This
could be rotatable as a double extended Zepp.  The question is this....what 
would the
center impedance look like?

For 40 meters this would be about 160 feet of wire on each half and should 
work as
a rotatable DEZ and work 80-10 meters just as my full size DEZ on 40 
presently works.

All help would be appreciated.
