Ed:

     Besides extending the length of the downhill guy, you might consider 
using an elevated guy anchor.  This is a steel I-beam of appropriate 
dimensions embedded in enough concrete to resist overturning when the wind 
blows against the guy wire.  Its length would be tall enough so that enough 
is embedded in the concrete and enough is sticking out above ground so you 
can attach your guy wire anchoring devices.

     Rather than point you to other Hams' examples, I suggest you do a web 
search on elevated guy anchors and see what comes up.

     A final point:  you need an engineer to design this thing.  Don't rely 
on my flimsy description (note my use of the deliberately indeterminate 
adjective <enough>) or others that you may find on the Intergoogle.  If the 
anchor is done wrong, the tower will come down.

Caveat Amateur.
