Brian,
I suggest that you study my work on this. Fundamental concepts are in
k9yc.com/RFI-Ham.pdf You clearly are not aware of the fundamental
concepts on which effect HF and MF chokes are based.
A coil of coax is NOT an effective choke at HF.

If you had enough extra feedline at the spot you wanted to install a
secondary choke, a simple solution for a single band might be a coiled-
coax choke. These air-core chokes act as a trap with very high
impedance. The length of coax required is somewhat less than a quarter
wavelength.
