 Another option if they fit would be a pair of bolt cutters. No sparks.

p.s.... wear a good hat, gloves, heavy shirt, and goggles or face mask
no
matter what you use.  Getting burned by the grinder plume ain't nice
when
you can't get away from it.

Help with saw blade selection

I've used a skilsaw on top of a tower to cut
u-bolts... not easy to position
because of the guards and hard to avoid the
plume of sparks.  I much prefer
the hand grinder.  Much smaller and easier to
get in around stuff.

One warning if you have to cut u-bolts... it looks
obvious to cut them from
the side where the straight section is away from the
mast, avoid that
temptation.  The normal result of that is the one side parts
and leaves the
long, now hook shaped piece, hanging on to the antenna but now
with no way
to get it off except to cut the other side... but now with an
antenna that
isn't firmly fastened down.  The best way I have found is to do
all the
rigging so the weight is off the bolts and then cut them at the middle
of
the U so they separate cleanly and let go of the mast or boom all at
once.
That is usually the safer place to stand also as you aren't under the
boom
or elements.

    You're looking for a metal
cutting aggregate blade  for your Skilsaw. 
They're cheap (less than $5) and
will zip thru any metal  quickly. The
problem is that the Skilsaw is heavy and
awkward at altitude but  it'll work
FB. 
 
    My favorite tool for this is a
4.5" hand-grinder.  They're not very
expensive. Get the smallest cutting blades
for it (I think  they're 1/8").
And they're lighter and easier to use.
