    I just got a used 25G tower. 2 - 10ft sections, plus the torpedo top section.
    Currently it has no provisions for mounting a rotor. Can someone point recommendations/instructions for installing a rotor to turn a small load beam. (no more than 9 ft boom). For something this small is a thrust bearing needed? If not, what sort of plate do I need to mount the rotor in torpedo top tower?

    Top Notch work!!! His stuff better than Rohn makes...I use several of his products.
    The top section as long as the mast pipe fits and does not rock around in the sleeve That small of antenna should be fine. I did weld a flange on top of mine and mounted a bearing but antenna was bigger...however any movement that rocks to and fro will take it's tole on the rotor.!!!

    Another GOOD GUY!...I would think the AR22 or AR33 would fit your needs(nr bottom of page)...Don't skimp...get a rotor that is bigger than you need...they will give you many, many yrs of good service if not overloaded and mounted correctly. Never know when you may want something else a little bigger antenna wise or want to add a vertical or another smaller beam for another band above your existing array.
    All the Best
