Thanks for all the input received.
In short it seems like lifting the coil would not do much difference.
Raising/increasing the angle of the top loading spokes might be the better
option.
Then of course moving the antenna to the water and improving the radials

Amen Merv,
You hit the nail on the head ! !

The discussion is about the placement of an additional loading coil and its
influence while the radiator is already loaded by a capacitance hat.
So who spreads misinformation?

One additional point about this that I might not have expressed in enough
detail.
When a top hat with significant capacitance compared to distributed
capaciatnce along the radiator is involved, current tends to become very
linear throughout the radiator no matter where any loading inductance i

How much I can improve by moving the coil up. What improvement should I
expect if center loading at about 7 meter? How about moving the coil all the
way up to the top loading spokes? Is it worth the effort? (the pole won’t
support much up there).
The coil does not do much at all to current
antenna.
Good luck! Have fun!

Here are some question for anyone with more tech skills than me;
My compromise vertical at 8Q7BM is made of thin wire attached to a DX-Wire 15
meter glass fibre pole. The vertical wire goes all the way up, but as the
pole’s top sections are very thin/weak the three top loading spokes (each 12
