Hello all. I have acquired one of the AB-577 mast kits with the extension to 75'. I am needing to erect this on a parking lot type area, asphalt. We are not permitted to penetrate the asphalt so we n
Robert, You did not indicate what will be at the top of the 75 ft AB577 mast. That will also have some bearing on how strong your guy point should be. Since you are on a parking lot type area, I assu
<snip> I really like the idea of the drive-on guy anchors. In addition to Henry's suggestion above, I would make sure that you collect the keys of the vehicle owners. This could be a disaster if some

I'll chime in here as I have used AB577 towers for Field Day for the last 8 or 9 years. Read the manual and then read it again!! Use 7 people to erect this if you can, 3 holding the upper guys and ke
I'll second Bob's comment about the bubble level. It's useless. The rest of his comments are spot-on in my experience. I didn't mention earlier that I have three AB-577s, one with the extension kit,
