wx0b'S presentation to the PVRC has the following rules of thumb.

1 wl booms space 1 wl
.75 wl booms space .87 wl
.5 wl booms space .707 wl
.25 wl booms space .5 wl.

The following note is also attached: "short booms are very critical,
model it to be certain.

For what it is worth, I had independently modeled a pair of 3 element
CC TEN-3 beams in EZNEC.  The top at 85'.  It turned out that the best
spacing was about 18'-very close to the above table.
