Help with tower Identification and Configuring.

[Sunray-Skip]

Here's the tower in question any help in ID'ing it would be great. Verticals are 1-1/4", approx 17-3/4" from outside edge to outside edge.

It has a mast pipe that is adjustable (see image below A), currently raised as far as it will go. This mast pipe has a square section clamped in the middle (see image below C), see close up 3rd image down. Is the mast pipe one piece with the clamp at image 3 clamped in the middle, or is this something that joins to pieces? I'm wanting to mount a VHF antenna on this mast pipe and raise it as high as possible, and if it's just clamped, slide it further down the mast pipe.
Any criticism or advice is welcome.

I don't think there would be a reason to have a clamp in the middle just to have a clamp. I'd guess it's actually connecting 2 mast pipes together.

Yup, good 'ol Rohn 45. A little on the beat side if you ask me.

It's a tower to die for!!

It has a shackle on it that connects to a wire rope for lift. I was thinking the same thing, but what is the lower section of pipe for? The clamp section can't move past point B, so what would all the pipe below there be for?

Thanks for the ID. I agree that section looks ratty. But the price was right - it came for free with the property.
The only section that's rusty like that is the top 10ft section. All the rest of it is like the bottom section in the concrete. The rust on the top section appears to only be superficial, and I believe can be treated by a light sanding with scotch-brite and painting with cold gal or Kill-Rust Primer/Paint. Tower has very well done guy anchors and was nice and stable with my 196lb ass at the top.

The rotor plate is down below, inside the tower. That's why the mast goes that far down inside the tower.

That does make sense, though Point D is currently a large clearance hole, but it's possible there was a bear plate there at some point. Currently the two bearing plate are located a point B and the point in between A and B.

Rohn 20, 25, 45, and 65 towers use tubular vertical elements. If condensation forms on the inside of the tubes, the tubes will start to corrode from the inside out. In other words, the tower could be rusty in places you can't see. Could make for a dangerous situation if someone tries to climb it.

You forgot the old short lived Rohn 35G Tower they were built as a Motorola Tower and not sold to the public. I have seen a few just not many in West Tennessee and West Kentucky area when I still did climbing.

Ones of these used to sit on Point D. A wire went down the tower and inside the building to a control box that would indicate which way your antennas were pointed. You could adjust the control box and it would rotate the mast pipe to change the direction the antennas were pointed.

Just like the old Toyota Tacoma frames, they do rust from the inside out. Inspect thoroughly before using.
