Uh, i "got that notion" from every single book on the subject, i own, from
about 30 years of antenna experimenting, winding my own baluns, building my own beam, vertical, loop, and horizontal dipole, zepp, and other antennas. I might ask YOU where YOU got the notion that "RF ground and DC ground are two seperate things". They most certainly are not. ground, my friend, is ground, period. if you are going to ground the signal element of an antenna, you are going to either get nothing for a signal, or a highly reduced signal, depending on just how long your ground path is. ground is a funny thing at RF, and it becomes progressively more difficult to get a good one as the frequenncy becomes higher. Yes, there have been antennas that were buried in the ground, but that would refer to antennas that operate in frequency ranges so low that it would have little or nothing to do with scanners ! (when was the last time you listened to 160 meters on YOUR scanner) ? I get extremely tired of being second guessed by people who *** think *** they know something, and know almost nothing about the subject under discussion, and like to adopt an opposing, diametrically opposed view point on almost everthing, like yourself, simply for the sake of being "different", and stirring up trouble basically. I dont know where you studied antenna theory , but what you had to say here is seriously "out to lunch". I am certain that Bill Orr would be glad to argue with someone like you, he was the author of quite a few thick tomes on this subject, and was world famous. I wont waste the time on you. Sorry. Life is far too short to waste on this. ground is ground. anyone who knows anything knows at least that.

They most certainly are not. ground, my friend, is ground, period. if you are going to ground the signal element of an antenna, Hardly true at all. The antennas that I use here on HF are all directly grounded at the matching transformer. I could take you out back and we could run the meter between the antenna itself and the ground rod and you would find it to be a direct short. That's a DC ground, not an RF ground. Then I could take you inside and have you try to tell me that reception was reduced. LOL you are going to either get nothing for a signal, or a highly reduced signal, depending on just how long your ground path is. ground is a funny thing at RF, and it becomes progressively more difficult to get a good one as the frequenncy becomes higher.

Yes, life is to short to waste explaining to someone who thinks he 'knows it all' the difference between RF and DC ground. Get back to us when you finally pass 'Antenna School'.
