I don't want to start a war...but with all due respect to Jamie,
I have to disagree with the notion that AB-577 movement and
installation can't be one-man jobs. I own three of them, and
have transported and erected one or more several times by myself
with absolutely zero assistance.
The trick for transporting them (i.e. - loading in a truck bed
is to pull the tubes and carrier out, move the pieces, then
reassemble in the truck bed. Of course it adds 10 minutes
or so to the process - but these sorts of things shouldn't be
done in a hurry anyway.
My typical one-man installation time for a standard 50-footer
runs about 1-2 hours, depending on the complexity of the antenna
stack (long VHF yagis, preamps, HELIAX, etc.), and includes
shoveling a level pad in hard-packed decomposed granite soil.
Sure, I get some exercise in the process, but everything has
always progressed smoothly.
So far, my only problem with the AB-577 system is that the
standard guy stakes are too short for handling high gusting
winds (75-90 MPH w/ long gusts 95-110 MPH)...and forget screw
anchors in our soil. You might as well try to screw one into
cured concrete. I'm considering some concrete base pads and
guy points at home for semi-permanent use.
Good luck & 73,
Dan KB5MY/6
