No need to build one, Tom. Diamond has already built one for me.
It's the model NR72B. On 2m, the coil acts as a normal loading
coil. On 70cm, the coil is a phase-reversing coil with 1/4WL
on the bottom and 1/2WL on the top. Kraus describes that exact
antenna on page 824 in Figure 23-21(c) of _Antennas_For_All_
Applications_, 3rd edition. Richard H. can verify that.

Kraus describes the antenna. Diamond builds and markets the
antenna. Do you believe that Kraus is wrong AND Diamond is
engaging in fraudulent marketing practices? You might get
rich and famous by suing them. (Then again, they might just
laugh at your ignorance.)

My Comet 2x4MAX also has phase-reversing coils in it. This is
the 21st century, Tom. It's past time to BBQ your sacred cow.

It is well known that a 3/2WL center fed antenna, like the G5RV
on 20m, undergoes some current phase reversals. That's what gives
it the cloverleaf pattern on 20m. If we make a helical G5RV and
use it on 20m, do you think those phase reversals will go away
simply because we are now dealing with a coil? Please rethink
your position.

If I remember correctly, Tom Rauch tried this and couldn't get it to
work as it was supposed to.

When an experimenter believes something is not going to work, it
usually doesn't work. Any number of reasons come to mind.
