This tower started off as a 7 section AB-577 that sits on the cage (inside the launcher) that the tower is packed in for transit. This was a new addition in the summer 2000 rebuild to hold the C3 tribander up at 45'. The beam is turned by a Ham III rotator, I bought from one of the guys at work (an ex-ham) for $100, new unused in the box. It seems to be happy so far....
In the Fall of 2003, two more sections were added, and another guy set, to get the 40-2CD 40M beam up a little higher (55').
