I’m looking for ELF (800 – 1500 Hz) and VLF (20kHz to 40kHz) commercial receive loop antennas. Thought I’d ping the group for any recommended vendors to look into.
?
General specs:
Receive only
4ft x 4ft, or smaller. Square or circular is fine
Active (with preamp) preferred
E-field shielded preferred, but not absolutely necessary
