Hi all,
I’ve been experimenting with a more compact H-field loop antenna setup for my station — mainly because I’m in a pretty noisy urban area with limited space on the roof. Switching to a twisted pair loop with a ferrite-loaded core has actually cut down some of the EMI for me, maybe by around 30% compared to my old open loop.
I also tried putting the preamp in a grounded metal box, and that definitely helped a bit more.
Curious if anyone else here is dealing with tight spaces or lots of RFI?
Thanks in advance!
