[TowerTalk] Rotor location

[Wayne Kline]

My first question to you is A: what size mast are you using  both OD and Length  B: what antenna do you plan to install ?
 
Why    That top section can be used with the rotor shelf on the top set of rungs of the Rohn 25. 
But that's ok if were talking about a C-3,  A-3   TA 33 ect.      but if your going BIGGER  the problem comes when it's time to repair or replace the rotor
 
 The little stub  is hard to keep centered by your TB3 ....  if you lower it far inside the #25   the cross rungs  can become a problem.

> I am getting ready to mount my rotor. At the top of the Rohn 25 sections I am using A BPL25G thrust bearing assembly section which has the top plate approximately 18" above the 1st section of cross members. My plan is to place the rotor at the 2nd set of cross members on the top section.

> Thank you in advance for the advice. Wanting to make sure I do this as best as possible.
