I shunt feed my tower for Topband. Presently using a Comtek 100 bead balun. After reading K9YC's article on baluns it would seem that a stack of five #31 cores with 7 turns of coax would be a better balun. Would I notice an improvement in any way by switching baluns? If the answer is I would notice an improvement what about using sixteen turns #12 THHN wire on #31 core as shown in K9YC's article? How many cores would I need for 1500W? Tnx for any feedback N2TK, Tony
