The book you probably want is the "Lineman=92s Handbook" =
published by McGraw Hill. It is relatively expensive in the $70 dollar =
range, and about 800 pages. It has a lot of interesting information on =
pole hardware and installation standards used by the power utilities.
I think they call the type of guy anchor that you have an "Everstick" =
guy anchor. The way you set that type of anchor is to auger a 12" DIA =
hole in line with the guy wire. With the Anchor disk attached to the =
guy rod, and positioned in the bottom of the hole you take a inertial =
driving tool (essentially a heavy piece of pipe that fits over the guy =
rod) and slide that hard down the guy rod several times until the disk =
is fully expanded. If I remember correctly there are also truck mounted =
machines that set those anchors. =
