George,

Let me expand on my earlier comment. The purpose of radials is to reduce 
losses in the earth under a vertical. It matters less what directions those 
radials run than the quantity of them and their length. If I had the wire to 
run 6 more radials, I would run them somewhere, but try to avoid running next 
to the Beverage, especially running in parallel with it. 

>From my own experience, and from studying the literature, more radials DO 
improve the performance and stability of a vertical antenna. My own radial 
field (60 radials, varying in length from 50 - 120 ft), is far from 
symetrical, but the performance improved each time I added radials, Also, the 
performance of the antenna seems completely unrelated to where the radials 
are, but strongly related to the topography of the mountains to the north and 
east of me.
