[TowerTalk] AB-577 Surface Guy Anchors?

[Robert West]

50 pounds on top I estimate.  I didn't think about vehicles because this
would be up for 4 or 5 days for a ham fest memorial day weekend.  I got this
tower from an old ham who said he was getting too old to handle the thing.
He had it up 5 years straight but he had it bracketed to the side of his
house as well as the guys.  We have the thing pretty much refurbished and
looking good but as someone mentioned, it would be like a noodle even with
guys that are with it.  Has anyone had any experience in adding additional
guys to this setup and would it make any difference to the stability or
would it just add to the complications?

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 assume that you can park 
vehicles on the surface.  If so, then make a frame assembly that can be 
held down by the weight of a car/truck by driving a wheel on top of the 
assembly.  Or, if you have vehicles with towing capabilities, then use 
the tow hitch assembly to attach guy lines.  If they can handle a 
3000lb boat, then they will handle the 577 mast easily.

Oh, be sure to have the vehicle owners sign waivers relative to any 
damage caused by a falling mast.

73,
Henry - K4TMC

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 need to fabricate a
method to anchor the guys on the surface, such as with weights.  I've 
seen a
method that is used for a non-penetrating mount for large dish antennas 
on
roofs that consist of steel angle iron welded in a frame and filled with
concrete cinder blocks bolted together with threaded rod so that they 
don't
move.  Works well in that usage but how about something similar for a 
guy
anchor?  This is a temporary thing so it would need to be easily 
removed.
But my real question is, besides any other ideas, how heavy would I 
need to
make these 3 weights?  The height is 75' and is rated for 75mph wind.  
Would
feel safer if the guy anchors could give us 100mph just to be on the 
safe
side.    Maybe a layer or 2 of block and then sandbags?



Any ideas?
