I've been in my home for 10 years and have finally decided to get rid of this mysterious eyesore in my backyard. It's a roughly 4' x 4' concrete pad, with two 1/4-inch x 6-in steel pipes installed vertically, but cutoff with a torch before we bought it. The pipes are ~27" apart, extend at least 2-ft below the surface and the concrete is at least 6-in thick at the edge of the pad. I've chipped away at the edges with a 6-lb sledge and found it's not going to break up easily! I'd like to satisfy my curiosity and also figure out how I need to upgrade my removal strategy.
So what is this thing?!
Extra details: The house was built in 1995, I live in Michigan, the pad is ~50-ft from house with no other structures nearby.

Was probably a ham radio antenna--the kind with a center pivot and a single pole above (sometimes called tilt-over). I had one like it on a property I owned. I just flexed a reciprocating saw blade down to the concrete and cut them off flush.
