<< * The mast has 4 guy rings at 10 ft intervals.  Do I need to guy at
 every one of them?  Was planning on guying at the 20 and 40 ft levels if
 that is sufficient.  

       Yes, you need to guy each level.       
 
 * Will use 1/8" double-braid Dacron (the black outer braid on a white
 inner one) for the guys.  I think it has a rating of 420 lbs.  Should be
 plenty strong enough, no?

     Maybe. I didn't know that they made a 1/8" version. Is the 420 pounds
ultimate breaking strength or safe working load (big difference there)?
 
 * Planning to stake the guys at 60% of the mast height (24 ft).  Seems
 like I read that figure in the ARRL antenna book. Do I need to go out to
 40 ft? Some other distance?
 
       As long as the anchors are all equidistant, that'll probably work. Any
hints from Rohn? 

 * Ideas for good, cheap guy stakes?  Have several T-style fenceposts
 that I could use.   Would like to have the guy ropes up about 4 or 5 ft
 above the ground to help minimize hassles when mowing/walking - what's a
 good way to do that without having to dig a hole and plant a concrete
 base?  >>

      The aforementioned fenceposts are way too soft for elevated guy anchors.
You need some pipe or I-beam to take the forces. You'll need to dig a hole and
plant a concrete base anyway - no way to get out of it with elevated guys.

      Are you in Jackson County, MO?
