I have an antenna tower in concrete behind my garage that has my local
tv station antenna. It is a big yagi type antenna. It has been there,
both the antenna and tower, for 12 years. I am getting a little older
and dont have any help and to be honest, dont like climbing up it. I
think the tower is 25 feet ot so from it's top to the ground.

Would it be possible to make a hinge for this thing so I could bring
it down to replace the anteena? Can I do it now that it is already
errected, maybe loosening at one of the sections and pulling it off,
installing the made hinge then putting back on? Would I be able to
lift the tower and antenna by myself once it is pulled off to install
the hinge. I appreciate any help.

There are a lot of different tower types, 3 sided, 4 sided, steel,
aluminum, tapered, straight... And within those, there are different
sizes, depending on how much antenna and how tall. If you can figure out
who made your tower, it will help you find stuff that would work with it.

There is a lot of tower stuff available in the ham radio world. If you
have the right size tower for this particular unit would be a piece that
uses the tower tubes a guides and rides up and down the tower with a
rope: http://www.texastowers.com/glenmartin_hazer.htm. Texas Towers has
quite a bit of tower related hardware. Another vendor that has a lot of
tower hardware is: WWW.DXENGINEERING.com. Another one is:
WWW.mfjenterprises.com. If nothing else, you might get some ideas on
what is being done.

Good Luck,
