I am currently using 16 turns of #10 wire for the 50 ohm side and 3 turns of rubber insulated 16 mm2 wire for the low impedance loop side. I would have to use smaller diameter wire or a larger diameter core to fit more turns in. -- 73 Warren K2ORS/WD2XGJ FN42hi http://www.w4dex.com/wd2xgj.htm -------------- Original message ---------------------- From: MarkusVester@aol.com > Warren, > > any chance to use a higher number of turns?
