[TowerTalk] LM-470 D and Rotors

[K0DAN]

I have used several of the Yaesu SDX/DXA rotors in a Tri-Ex LM470 tower. I 
was able to transfer the Yaesu bolt patterns to the "Ham-M" base plate, then 
drill new holes. Works like a champ. Can't address other rotor models.

I am replacing my current LM-470D Tri Ex tower with possibly another one. 
When I do, I want to use a different rotor in it. Currently I am using a Ham 
IV with beefed up parts and that has held up reasonably well but not without 
failure. The paperwork I have for the LM 470 says a “Ham” style rotor or a 
small prop pitch is what will fit. I am also aware that these parameters 
were written many years ago and circumstances have changed and new rotors 
have come onto the market. I am aware that if one uses spacers between the 
rotor plate and the base of the rotor that a T2X will fit in the tower. That’s 
good but what else will also fit the tower? What kind of rotor, different 
from a Ham-IV or T2X are you using in your LM 470 D tower or do you know of 
someone using something other than what I have mentioned?

Thanks very much
