I am NOT a radio expert, but I have never seen a long wire attacted to an SD mast during the war. Sometime in mid-late 1945 the sub force decided to add the VHF whips and shorten the long wires to an array surrounding the CTs with one of the legs running up the shears on the PORT side. Someone said it was to clear up the field of fire for the gunners, but hell, it still puts a wire or two near the gun mount...
So if BATFISH is true to a focus date that reflects her post war CT mods, then the wires should probably be run around the CT and up the shears on the port side. I will look for post-war shots (they're there, I know!) of this arrangement.
