This is what I had built http://youtu.be/_ZlvBvIT1_k

I am starting to get what you are saying. I pretty dense so could you do a sketch? What size pipe?

Deign This is what I have been looking to build. This tower while only 23' weights around 620 pounds.

2" OD aluminum I think it is .125". Don't know the weight of the antenna. That's why I guessed at 400 pound for tower and other equipment attached to it.

Yes I did. The tower weights 322# and the guess of 400# would cover the equipment on it. Just added more pictures on my webpage wb0sbu.com

The base is 6' deep and 5' square. The anchoring legs go to the bottom.

Because you ask This is what the tower is and has been up for two years. http://wb0sbu.com

Finely an answer to my question. Very good. Now I can proceed. The tower is up now so lowering it will be next.

No on the trees. Just need to the force applied to the cable.

This is a heavy duty all aluminum and is designed to be raise by hand walking it up. I don't have any help so I need to power it down and up. If it doesn't work i'll have scrap aluminum to sell.

This seems simple but I am having trouble with this. I have 70' self supporting tower that I want to be able to raise and lower with a winch. The tower is hinged at the base. I want to use rectangular steel tubing 7' high with a pulley at the top. See PDF attachment. I need to know the force...
