Dan, et. al.,
When you invert a Bobtail Curtain antenna, you are moving the
HIGH CURRENT part of the vertical element next to the ground.
The phasing wire will act as ONE radial for the outer elements
and two radials, for the center wire. NOT a good ground system.
You would be better off with phased verticals and LOTS of radials,
preferably 30 or more, under each element.
OR, install the Bobtail as intended, with the phasing wire on TOP.
