[AMSAT-BB] Looking for US Tower M-10 Mast or Equivalent

I would like to upgrade my HF/SAT antenna system, but I'm having difficulty quickly finding a suitable mast these days. Does anyone have a 10 foot 2 inch OD steel mast (such as the M-10) that I could buy and pick up somewhere in northern New England, ideally within 200 miles of Maine? Thanks.
