A BalUn would help a lot.

For what? If the antenna system is balanced (as are dipoles, inherently), I
seriously doubt a balun would be good for anything.



Most every practical dipole installation has some imbalance in the
installation (the trees are closer to one side than the other, etc.).. a
choke to prevent RF current from flowing on the outside of the feedline
will at least make the pattern more consistent with expectations.
Might make the tuning less "twitchy" too (because you've decoupled the
effect of things near the feedline).

Certainly, a choke at the entrance to the shack is a great way to keep
RF outside.
