I recommend not grounding the tower. Makes it harder
to load up. Find a good ceramic insulating base like
you're supposed to have, and the correct guy wire
insulators spaced to minimize interaction with the
radiating element, the tower.

SHUNT FEED works fine with a grounded tower.
That is what I used on 160m at one time and it worked
very well.
A grounded tower is safer.

I have used both shunt feed and sloping wire feed through a series capacitor on
a grounded tower for 160M and it works wonderful!! Just takes a little
tinkering to get it right.

I prefer the base insulator and series feed myself. Shunt feed or unipole
feed works great if the tower is close to a resonant length. It becomes
more difficult if the tower is much shorter than natural resonance.
Sometimes top loading will make shunt feeding easier, since it raises the
For my 160m shunt fed tower I had a Rohn 25 - a 60 footer
with a few feet buried in concrete...
So I dug out some old articles on how to do it.
Now, I DID have a good capacity hat in the form of
a 4 element Swan TB4HA beam at the top.
AND an 11 element Cushcraft bean on 2m FM above that.
