Yagi efficiency
It occurs to me that by art's definition, all antennas are
"inefficient". When you're talking with someone, only a teeny, tiny fraction of the radiated power is going precisely in the right direction to be collected by his antenna, so the remainder is wasted. Shucks, I'd be amazed if the "efficiency" of the best HF antenna is better than 0.001% by this criterion. Roy Lewallen, W7EL |
