So for most of the dipole based antennas (including Yagis), you
can use 6 turns of 4" diameter coils in the coax, to make an inductive
loop that is supposed to prevent current from moving down the outer
braid (non-radiating).
6 turns is probably not enough inductance to do much choking on 160m
or 80m.
If the dipole is non-resonant, 6 turns of coax may have very little
effect on any HF frequency.
It took 27 turn here to get decent choking on 80m. But it finally
worked 6" diamater selenoid wound.

P.S. feeding a OFCD cut for 3.6 MHZ. Thru a 4 to 1 Balun.
