The HD-73 is a very small rotator.  I use it in my
skinny field day tower.  Nothing else will fit.

The "Spid" rotators (sold by AlfaRadio and Array Solutions in NA) are pretty skinny, except for the motor which would probably stick outside of your top section, but the motor is stationary so would not cause a problem (until you retracted the tower).

Have you considered mounting the rotator on top of the tower? The Spids are ready made to sit on a mast, and their mechanical design is better for that application than most other rotators. As long as you don't need a tall mast and stacked yagis (I'm guessing that is not in the cards for a tower that won't hold a CD-45), it might be the most sensible way to proceed.

I have been trying gather the information from a bunch of places, and decided to just go to the experts here.

Our radio club has a couple of very nice trailer mounted crank up towers. I believe they are from U.S. Towers, but I am not sure. The top section of these towers has a rotator plate, but the section itself is a bit small. You can slip a Hygain CD-45 rotator into the tower and it will bolt to the plate. But it can only turn about 60 degrees as the bolts on the CD-45 run into the tower legs.


   1.  What rotators are "narrower" than the CD-45?

   1.  Which rotator is the most narrow?


Thanks and 73,
