So if you want 100% efficient antena you better use full lenght antena. Not possible in these purposes. So logically Esteban is right, in this purpose antena must be much shorter than physical wavelength.
Taking any turns for any frequency will result in catastrofic reception. So some rule must be respected.
If you remeber i suggested 455kHz receiver design earlier!? Do you?
You know why? Just because i wanted to make your (and my) life much less complicated in future when design step in practical phase. Instead discovering "hot water", i would further sugest just ordinary ferrite rod antena taken form some scraped radio....simple as that.
But no...my suggestion was never accepted properly, just cose same reasons as here...smart asses usually do not read and try to understand but usually listen only own voice and read own words...others...who cares??
You must understand me, it is damn hard for me to be at same level of thinking with you (again i am not trying to offend). But those are elementar and real basics....you have to learn at least that to be able to understand further things...Without that elementary knowledge you are wasting my time here (reffered to Esteban mostly).
