Thanks..I've looked at alot of your info on-line--especially the
sub-500GBP AO-40 setup.
I guess I still don't get it..if I just feed them in-phase with both
connections same polarity, what controls RH v. LH?
Or is it RH if the front half loop is to the right and LH if the front
half-loop is to the left?
Too cold to not get it right on the first try!!
