Hi Richard

My 5 element 2m yagi is setup that way but I'll admit I didnt do it in a
pretty manner.

The attachment on the rear of the antenna has 2 U bolts for the mast and two
plates shaped to fit the boom over about a 6 inch length. I simply put some
washers (spacers) between the two plates so the boom would interference
fit.

I then pulled the boom back a little so maybe 2" was showing behind the
clamp, drilled a hole in it and bolted a flat piece of gal steel strip
about 2 ft long either side on it. The ends of the gal flat were also
bolted together.

I then attached a piece of rope to each end of the gal strips and greased up
the inside of the clamp plates.

Real horrible but it works!

Hi. Has anyone designed a way to mechanically rotate their VHF/UHF yagi so
that it can be either horizontally or vertically polarized? If so, can
you
please direct me to a website or whatever. Preference right now for a
manual system, but would also take a look at motorised systems.

TIA.

Rich.
