The Delta 240 is a coil version, and does not use linear loading.
I've never owned a Cushcraft but I've had the linear loaded 2 element 40
and two versions of the 240. The first version had coils enclosed in
pvc and the current version is wound on some sort of plastic form. I
went to the new version when I ordered the Delta 240/230 beam which I
should have done in the first place. Having 2 elements on 30m makes it
easy to work pileups.
Both Delta's tuned very easily based on the dimensions given. I just
pulled them up the side of the tower about 30' to check the swr and it
was exactly like the manual said they would behave at the low height.
Once they were raised to the top of the tower the delta's resonated
right where the manual said they would.
The linear loaded 2 element 40's took more work to tune but once tuned
it played well. The one thing I missed was the relay box option which
would allow you to switch between cw and ssb with the flip of a switch.
Now that F12 sold to InnovAntennas, I'm not sure if the 240 or 230/240
will be available. I know the C31xr will be.

Does anyone have a Force 12 Delta 240 up in the air in use? If so, how
does it play?
I've installed a number of the F12 linear loaded antennas and NO ONE
has ever said to me that it was a 'great' antenna. I've always thought that
the CC 2L shorty forty is the best bang for the buck on 40M. Maybe the
newer F12 versions with coils would be an improvement.
