Pete;
Take a look at American Earth Anchors (americanearthanchors.com).
I used their Penatrator model 46inch guy version on 100 ft of 45G a few
years ago.
Only real spec is to be used in un-disturbed soil . I installed the tower
on an acre of
farm land that had never been filled or mucked with in 100 yrs. These are
aluminum and wont rust in
most soil . I installed them by hand due to being unable to locate the
electric tool they recommended
in my rural area. Rocks are no issue for this version I can assure you.
W8JI has some good info and lot's of warnings.
GL with the project,
Tim , AB4B
