Topband: Shunt fed tower

Ok not sure where to start.
I decided to redo my vertical.
I have a 89 degree tall tower. (125 feet self support).
It is shunt fed (#6 copper) 55 feet above the elevated radials three
feet from the tower.
There are 5 radials, 130 feet long.
There is a 1 to 1 transformer I wound and a number of ferrites around
the cable below.
Checked the windings of the toroid to make sure there was no shorts.
When I check the feed point I see Rs=0 Xs=45.
Did these tests with a few different cable lengths results the same.
I swept from 1600 to 2100 and it changes a small amount.
What am I missing, Rs=0 ?
My previous install did not have the toroid.
I have not added any capacitance to it yet as the Rs has been confused.
I did connect it to the transceiver and it has respectable rx.
