Mauri,
What you say is true -- unless you have a HAZER tower. At least it is
for 20-10 m quads.
Alternatively an EZ-way tilt over tower makes the job easy too.
Unfortunately, EZ-way towers haven't been built for 15-25 years and
you'd be
lucky to find one in decent shape. Too bad someone couldn't resurrect
this design....
The quad is easy to putup and work on.
You do need an 8' step ladder.
It is also easy to service (which you have to do).
The advantages in my case (max gain for min turning radius)
outweighted any disadvantages. Also, since there are no traps, high
power is no problem.
Multiband operation is also quite easy. Mine runs 20,17,15,10 on one
boom with one feedline.
Just like any project, you have to think through the installation
before you commit to an antenna.
