Hi All,

After the encouraging recent success I've had with my 6M K1WA/K8UR 4 sloper
array (similar to the one in the ARRL Antenna Handbook-, but modified), I'm
now considering another 6m or 10m array with slightly more gain, etc.

I know ON4UN does something "similar" on a 80m yagi in his

Has anyone played with a 3-element vertical wire yagi, (electrically
rotated) centered around a common point?
(no rotor)

IE: something resembling this (birds eye view) :

                  .        .
                  .        .

The center dot being a 1/4WL element. Each outside element (I'm thinking)
could be the length of a reflector
but with a small coil or linearly loaded piece of wire at the bottom, which
could be shorted by a simple SPST relay,
ensuring it was then short enough to be a director.

Therefore, this example might be steered in 4 different directions simply by
making one of the outside elements
a director (the rest remain reflectors, see?)

Ideas? Comments?
I'm not looking for as many posts as the Dummy load oil deal, but a few
comments batted around regarding
this reflector related post might be nice ;-)
