I think Roy is referring to a T configuration rather than an upside-down L.
The currents will balance in the T so wire size is limited by physical
considerations rather than electrical. This is just another form of a
capacity hat. The net result is to raise the radiation resistance.

Roy,

Thanks. This might be feasible. The site would support 50 foot wire from
the
tip. At 500 watts what would the current in the horizontal leg be? In
other
words what is the minimum effective gage?

What is the purpose of this leg? Is it capacitive or does it begin to look
like
something else. What are it directional characteristics? Dipoles nodes are
perpendicular while long wire nodes are parallel.

I agree with comments about adding a horizontal wire to the top of the
vertical; it will probably be easier than a capacity hat. I am
overloaded with work at the moment, but would like to attempt a model
in a week or so when I have less work.


Take a look also at a tee type arrangement. That is, a horizontal wire
with the tip of the vertical connected at or near its center. It might
have some advantages over connecting the wire's end to the vertical. But
of course it might be more involved to construct.
