[TowerTalk] field-day mast anchoring question

[Larry Banks]

We (W1HP) put up a "two-el" inverted-V.  Only takes two fiberglass poles for 
the centers and no guys -- the wire acts as the side guys and the poles are 
strong enough to not need guys in the fore/aft direction.  If you are not 
going to rotate it, why go to the trouble of a 2-el yagi?  (From the Boston 
area we just point WSW.)

Subject: [TowerTalk] field-day mast anchoring question


For those familiar with the AB-621 military launcher mast units.
Lets say there was an interest in using this on a field day event, where
there is a concern that the ground is too soft to safely establish
anchors.
Is there a possibility of using concrete wall-barrier blocks bolted
together, as dead-weights to safely hold the anchors?
For example, I think I can come up with a number of 60lbs cement
wall-barrier slabs that can be bolted together for each anchor point.
If this would be a viable option, how much weight on the anchor blocks
would guarantee a safe installation?
The intent is to put up a 40 meter 2 element yagi, without a rotor, at a
height of 50 feet.

Thanks in advance.
