dimensions of a tipped radiator in equilibrium some time ago on this

Your devoted servant

tipping a radiator is an obvious exploit of changes in pattern by
unbalancing the ground current. it gives some gain in one direction at the
expense of other directions. it is not all that useful unless you want a
tipsy looking antenna and are covering a fixed direction... unless you made
an array of tipsy verticals for vhf and rotated them... that might be fun.
besides i had enough bent elements from the winter ice, they didn't improve
the yagi performance. so i've had enough of that. but 'equilibrium' as
defined by art is a magic jewel to be examined.

i do take exception with 'dave' though, the equation should be Xl=-Xc or
Xl+Xc=0 to put it in art's form.
