Mark, If you are worried about mast interaction you might extend your mast with a short 2 to 4 feet of wood/fiberglass/pvc dowel and place the balun at the top of it. Since you already have a strong mast in place, an extension might be the way to go.
The dowel, properly sized OD , will slide down into the mast ID and you will have to use clamps or thru bolts to hold it in place. I suggest strongly that if you use wood that you treat the wood with a product such as Thompson sealer or something that penetrates the wood. I have done this a few times with good results. The balun should (as it is meant to) prevent antenna currents on the outside of the coax shield which would be the culprit to make the mast an influencer. To be blunt...I wouldn't worry about it, unless your feed/coax match is off due to balun mast interaction and that depends on the type/construction of the balun. .......but I guess rather safe than sorry is certainly a tact to take.
