[TowerTalk] Guyed vs. free-standing

Of course, everything Steve says about the comparison is true. However
nothing has been said about installing antennas on the tower. The self
supporting tower allows yagis to be raised vertically with ease while guyed
towers require working the antenna thru the guy wires. The Trylon or AN
towers look good to me although I use crankups and find them to be an
excellent choice. They can be bought used quite reasonably in SK estate
sales in this area and can be hauled on a boat or car transport trailer. I
will concede that the bolt together towers, either guyed or not are easier
to transport. These are some other factors to be considered.

So for this dummy, for a given height and load, in the 60 to 80 foot range,
does the guyed tower still retain its cost advantage when you factor in the
extra anchor points with the steel in them and the guy wire or Phillystran
for the tower?
