Big antennas, high in the sky, are better than small ones, low.

K1VR opines: I used stainless steel when I installed ym Rohn 25 in 1981,
and the nuts and bolts look today as they did the day they were
installed. A couple of tips:
1. Over order by 10%, to allow yourself to drop a few into the snow and
still get the project done.
2. An additional part of that "over order" will be used up as some items
"gall." There are compounds which limit galling, but you'll still waste
a few nuts and bolts.
3. Go back a month later and re-tighten the SS nuts and bolts. Some
will loosen up.
