I am in the planning stage for a 160 meters compact loop antenna. A loop
antenna may not have metal nearby, so I am planning to use a wooden pole to
support the top of the loop. In the ARRL Antenna handbook, it states that
"W5QJR made a pole of 2 x 4-inch lumber with 1 x 4-inch boards on either
side to form an I section. He held the boards together with 1/4-inch bolts,
2 feet apart and tied rope guys to the top. This made an excellent mast up
to 50 feet high."

Does anyone have any comments on the feasibility of an unguyed pole using
this same type of construction? Naturally, a portion of the pole would have
to be underground, and perhaps set in concrete. What about a 50 feet pole,
with 10 feet underground ,which would give you a 40 foot mast?

An alternative would be to have a contractor install a 40 feet utility pole,
but I assume the wooden pole described above would be less of an eyesore (to
the neighbors) than a utility pole.

Any comments and advice will be appreciated.
