Home recently purchased has concrete base which appears to have previously been used for Rohn TV tower. Remnants of tower remain. Is it possible, and how can similar tower be attached strictly for 2-meter Yagi. Appreciate all suggestions and/or comments. 73, Rich, N3NSN Never Say Never!

If you can line up a new tower with the existing base, you're all set!

Unfortunately, Rohn is Chapter 11 and not currently manufacturing any towers; however, many Rohn dealers have inventory, and lots of used Rohn towers are available.  Plus, other vendors are claiming to be in the process of setting up to "second source" the popular Rohn towers.  

If you can't find an exact match tower for the base, that could be a problem.  Custom fabricated adapter brackets can work, if they're well engineered; or, sometimes new holes can be drilled into an existing concrete foundation and large bolts epoxied into those holes.  However, such methods may not garner approval of a building and safety inspector, should this be required.

Also to consider, a lotta TV antenna towers
used Rohn-20G which is similar to 25G, but
not as strong.

Sounds like you may have fallen in to a great deal!
First thing I would do is research previous owners of the property and find out who installed the tower base,
and how large it is......  (One cubic yard of concrete is a minimum for a Rohn 25 tower.......)
How much of the old tower is sticking above the concrete now?  If a few inches, you might be able to have a sleeve made up that could be slid inside the existing tower legs and bolted in place. Rohn 25 tower is availabe used most everywhere if that is what it was.......  
Good Luck!
