Default Flipping turnstile

A turnstile is a horizontally polarized antenna. Big downer is that from a
polar radiation POV, from the sides, it's got a minus figure. Like -2db or
something.

Okay, flipp the turnstile so you have one dipole vertical. Not a turnstle
anymore, and the element configuration will respond favourably to both
vertical and horizontal radiation.

But:

1) Do you have to wire up the "flipped turnstle" in a different way in
order, at the same time, (without any switching) to take advantage of:

a) mixed polarized waves?
b) vertical or horizontal waves?

2) If you put up a "flipped turstile" and you wire it up to handle mixed,
vertical or horizontal waves, what is the polar radiation patter in the
horizontal plane (ie from the sides) ? Still a minus?

Amhoping that a "flipped turnstile" properly wired would perform with
mixed, vertical or horizontal waves coming from the sides. And hoping better
than a turnstile.

TIA.
