I am almost ready to put up my little 40' guyed tower. Everything is here
or on the
ups truck. There is a lot of discussion on mast stress and material type
but haven't
seen anything on how far the rotor should be below the thrust bearing. I
am using 2" o.d.
x 3/16" wall sae 1026 tuning. It came from the steel supplier at 21'-6"
long. I am mounting
a 4 el 10M vee (elements are up on 45 degrees on each side of boom) circular
polarized antenna
10' above the tower top. The rotor is a Yaesu G800SA. In the future I will
probable remove
the 4el 10M vee and install a 3 el tri-bander about three feet up and put a
small vhf stack on top.
How far down should the rotor be located in relation to the height of mast
above the thrust bearing?
I could use the whole mast but would rather minimize the weight. I want the
rotor far enough down
to minimize the side load on it. Any suggestions??
Thanks
