You can.

Looks neat, though. Pretty husky too...however...

I wonder about the fact that there is no diagonal bracing. The horiz

I'd not be concerned about it as much in a guyed installation, but I'd
kinda like to see then in a free standing tower.

bracing is quite heavy looking, but it looks like one giant parallelogram to

strong, but "I'd think" the box cross section would be more
susceptible (less resistant) to torque than a triangular one.
