Hello. Can the Rohn AS25G accessory plate be cut easily and with what type of saw? Without sacrificing strength can a Yaesu rotor GS-450 be mounted on a cut plate? I will be using a thrust bearing (T

JonHello. I purchased the TB-3 because the Yaesu GM-050 bearing didn't mount on to the Rohn AS25G plate. It wasn't even close! Believe it or not I think I might be overkilling the entire project. Thi

DaveThanks for the email. The mast was $66. It is ASTM 6061-T6511 grade aluminum at 1 1/4" OD, SOLID, not hollow. The weight of the aluminum was less than the 6ft steel mast that came with the tower.
