Proximity effect isn't a factor unless conductors are very close together -- I suggest you review the previous postings which explain it. As far as "better", the answer is that it probably doesn't matter, since either a wire or strap can usually be pretty easily made large enough to make loss negligible in those applications. Roy Lewallen, W7EL Proximity effect is when you are too close to a directional microphone and the bass is accentuated. I think you mean mutual coupling. Wrong one of the several meanings, Dave. See fourth entry under http://en.wikipedia.org/wiki/Proximity_effect. ;-) Thanks. Seems to be the realm of the esoteric however. |
