A few turns of coax will do the trick for 6m.
How about this solution from an earlier posting?

The choke balun made from a small coil of coax would be easier to make. At
my previous QTH, four turns of about 6in diameter made a big reduction in
the levels of noise and birdies on 6m (even though those coil dimensions
weren't optimized in any way).

This kind of feedline choke is simple, cheap and low-loss, so by all means
go ahead and use one. With a 3-element quad, you should be able to
position the coil at the feedpoint while supporting its weight from the
mast.

Using a choke made a big difference in TVI for me.
