Re: ccradio twin coil ferrite AM antenna?'s- FARMERIK
There was a change in which AM BCB frequencies were buried in computer and monitor RFI when I changed from CRT to flat screen monitors. For me that was a big help, since for listening while on the computer, I often tune in the 700's and the CRT's definately made that difficult. I don't know what variety of Flat screen monitors I have, but they moved most RFI up the band well above 800.toggle quoted message Show quoted text
I did buy a CCrane ferrite AM amplified antenna, and mine can be boosted farther by connecting one lead from my 2 and 4 foot [untuned] air cores to the ground terminal on the CCrane ferrite pick up assembly, and placing the ferrite near the center of the air core. It seems to be a bit wider pick up pattern, so from my location in the NE, I just place it to null the computer and it gets everything to my west and south west quite well without adjusting the 'beam'.
I decided to look into the Palstar ferrite and AOR loops too, but have not heard from anyone using them.
