I have done antennas this way and it works quite well - although it
requires more rigging to get it set up.

Most of the time I just use one haul rope from the top
of the tower and I "corkscrew" the antenna around the
guy wires. This is very easy to do if you do not
have any side monuted antennas. If you have antennas
stacked up and down the tower the tram method is eaiser.
I have found that I have little trouble getting simple antennas
- like a 40-2cd - around all sorts of side mounted lower
antennas - including KT-34XA yagis - so I usually use
this method.
