I should also mention my experience with my shortened 40m yagi. It was
a dog, without much directivity, until I replaced my steel tower-top
guys with Phillystran. Wow, what a difference.

Jonathan,
Before you conclude that your D240 doesn't have much pattern, run some
more tests on DX signals. From your QTH in Colorado, I would recommend
listening around your sunrise for signals from Japan and the far east.
Are you still using the Bencher Skyhawk/D240 stack as shown in the
photos on your qrz.com web page ? Does the Bencher Skyhawk insulate
the parasitic elements from the boom ? If not, it is possible that the
combined electrical length of the boom plus the uninsulated elements
is close enough to a half wavelength on 40 meters to have significant
interaction with the D240.
