Yup, makes sense.

Unfortunately the base is spaced out just a bit too far from the house to
be able to add a house brace that's strong enough. Why Dad did that I
can't quite figure out... of course, he had the mast at the time...

Also unfortunately, US Towers tells me that the bolt spacing on my base,
which was for a mast that was manufactured by a company that US Towers
apparently acquired years ago, is wrong for their current crop of crank-up
masts. :-( :-(

So, I guess I have a tower base that would hold up a (proper)
self-supporting tower through a hurricane, but I can't do anything with it. :-(
