[Antennas] 26B2 - puzzle for the weekend.

Tim,

I have a Cushcraft 214B, 14 element beam that I have configured for FM and
SSB.
I removed 1/2 of the elements and slid the boom thru a CDE TV style rotator
and clamped it in place. I then re-installed the elements. I mounted this
sideways on the Mast about 10ft above my TH-6.

I remotely rotate the antenna from Horizontal to Vertical. So the one
antenna works both polarities. This has some added advantages. Sometimes
there is a polarity shift on 2m, so I can compensate for this by rotating
the antenna polarity to optimize the signal.
This setup has worked well for the past 25 years.

I see no reason you could not do something similiar with the 26B2.
