Topband: current transformer 160m vertical

[Dick]

Hello all,

wonder if it is possible to use #26 material cores as current transformer on
160m
These are yellow/white cores used in computerpowersupplies.

Putting a stack of 10-30 of them around de coax might that help to stop RF
currents
on the outside of the coax, or is this material useless for this purpose on
1.8MHz.......

I know these powersupplies work on much lower frequencies, but I have plenty
of them
around, so wondering if.........
