[TowerTalk] tower identification - rotator plate

[Chris Howard w0ep]

Hi,

I'm a member of the Lowndes County ARC in Columbus, MS.

I'm helping do some work on a tower of which we have taken possession.
We want to put up a Ham-4 style rotator and a small tri-band beam
but we seek guidance on the rotator plate.

The tower is free standing.
It is approximately 100' tall.
It has three legs.

The bottom is made of bolt-together pieces of
galvanized steel angle.

The upper sections are galvanized solid rod.
I am uncertain about the section lengths.

The sections are joined by small steel plates
welded perpendicular to the ends of each of the solid rod
legs and the plates are bolted together with four bolts.

At the top there is a pyramid of solid rod holding up a piece
of pipe in the center of the tower as a mast/guide.

The top tower section is 1/2" solid rod with zig-zag bracing
of 3/8(?) rod.  The leg rods are 14" on center.

Driving around the area, it seems like towers of this type
are fairly common in the public service arena.

Our goal is a rotator plate.  Is there a "factory" plate
for this tower?  Is it something we need to fabricate?

Thanks!

Chris Howard
