    Well, going by what the manufacturers say - for a Hy-Gain HG-54D,(16
sq.ft.) you'll need 3 yds. in a hole 42" x 42" x 7 feet. For a US Tower TX-455
(18 sq.ft.), the hole is 3' x 3' x 6' with (2 yds.). The HDX-555 (30 sq.ft.)
hole is 4' x 4' x 6' and takes
3.6 yds.

    These towers are designed to be free-standing. I think attaching it to the
house is redundant and unnecessary unless the manufacturer recommends it.
