    Ended up ordering a maco 105c to put on the 60 ft tower vertical since I already have a Sirio Sy 27 4 element on horizontal then going to mount the starduster back on top of the horizontal tower thatis 40 ft.. just got to figure out how do you put a bearing in top of the Ron 25 kono's tower and mounting rotor underneath I know you need to plate.. ..

    The last time I set up some antennas I did that. I stood them on the end of the boom with the reflector element on the ground pointed skyward. It worked well. Better than horizontal only a few feet off the ground.

    Not sure what a 25 kono's tower is but in regards to rotor plates and thrust bearing plates for Rohn 25G... you can order from the following.. http://www.normsfab.com/plates.htm. https://www.texastowers.com/towers/guyed/rohn25g.htm

    That's what I did. You could also throw a rope over a tree branch and haul one end on the boom up. Or lean it against a sawhorse or fence posts. It's not rocket science how to point an antenna straight up.
