> Ok - have you a reference for Yada - seems to get all sorts of other > hits. Hmmm - really should have been "Uda" although Yuda seems to get used as well. I purposefully omitted mention of his more known associate Mr Yagi :-) Yagi Uda will give many hits. Between them they developed the classic Yagi antenna that you see as TV aerials and much more everywhere. Both were Japanese university professors. Uda did most of the development work but Yagi wrote it all up in English and popularised it.Which is my you don't see Uda antennae on rooftops worldwide today.
