Many thanks to SWLing Post contributor, Andy, who asks the following question in response to a previous post about building a Milk Crate AM Broadcast Loop Antenna:
All references to tuned loop antennas talk about no real connection to the AM radio, but merely inductive coupling.
However, I made a very elementary crystal radio which has no ferrite core or antenna.
I want this loop to be my primary (only) antenna, so I need to feed it directly to my tuning circuit. So I don’t know if I should take a wire from any particular part of the loop, with another wire to ground… and if these 2 wires should be in parallel or series with the tuning elements of the loop antenna.
Good question, Andy! Hopefully someone in the SWLing Post community can comment with some guidance!
