Not sure of the arrangement you are proposing...

If you are attempting to co-locate two of these near 
each other, and tie all the guys to the pair, I don't 
think that you'd get much of an improvement. First, I 
don't know how you'd effectively connect guys to two 
anchors at once.  More importantly, if I understand 
how they work, the screw anchors rely on a volume of 
soil (I think approximating an inverted cone) above 
the disk to hold them in the ground against the 
pulling force of the guy wires. If you locate two 
anchors near each other, IOW, so that these volumes 
overlap, you would NOT get 2X holding power.

You should get the expected improvement if you 
separated the guys (assuming you have more than one 
guy level) and put the top guy on one anchor, and the 
lower levels on another anchor (that's located closer 
to the tower).
