Thanks George.

The XM-240 book shows:

CW/Mid/PH

Ref: 262.5" (21' 10.5"), 258.5" (21' 6.5"), 255.5" (21' 3.5")
DE:  252.5" (21'  0.5"), 249.5" (20' 9.5"), 246.5" (20' 6.5")


So the driven is identical, but the reflector got 3-4" longer.

I copied two Cushcraft guys on my original post, hopefully they
can also respond to resonant frequencies and 2:1 SWR points
for their definition of CW/Mid/PH.

Thanks again George.
