Coax, will only exacerbate RF in the shack on an end fed long wire.  You
will have radiation back down the outside of the shield and if the coax is a
critical fraction of  a quarter wave at the shack end, it will radiate
there.

The unbalance in end feed with ladder line is only 10 per cent per L. B.
Cebik.

If the lengths are adjusted, you can expect minimal radiation problems in
the shack.

Or, feed the end wire from a parallel tank outside.  Then, you can on one
band at least, feed that with a link to coax.
