## Where do I put the rotor?

 Hi Tom I had a similar situation here using 25G. Guess it all depends on what u intend to put on the mast. If it's lite loading, u can put the rotor at the top and let the 10 feet of mast stick out the top. But the fact that ur using a mast that long, makes me think u're gg to stack something up there? I ended up using a longer mast(like 20 feet) and put the rotator (originally a Wilson but now a Create 3B) at the bottom of that flat top section. I had to cut out one horizontal bar from the 25G flat top section to be able to remove the rotor w/o taking it all apart, when rotor repair was needed (and it probably will be). I used one extra rotor plate above the rotor plate to put the mast thru (abt halfway or more up the flat top section) to hold the mast centered if u take out the rotor. Turns out ta\hat was a very worthwhile time saving move - since the mast will swing to the side of the tower if u remove it from the rotor. I did guy mine near the top of the flat top section with a Rohn guy bracket - altho sume mite agrue that it should be a the rotor where the torque pressure is. No problems so far with a 5 el KLM 42 foot boom 20 M mono stacked above a 2 el 40 M Mosley. I originally had a 4 el 40 M KLM on top with the 5 el 20 below but couldn't keep the 40 M 4 el together as well as the rotors (Wilson at that time). Hope all of this of some help. My 25 G has been up since 1978 w/o any problems. If u overload the mast, I have seen bent flattop sections with 25G (and even 45G) with the rotor near the top. 73 George W8UVZ >Hi -- > >I am replacing my Rohn 25 tube-top with a flat top section.
