Cheap AM Radio Loop Antenna - Does it work?

[@patrickwall8517]

That antenna works pretty well. I like the name you chose for your channel.

[@rfburns3472]

Thanks Patrick! I been burned plently of times by RF.

There must be a small capacitor in that loop antenna, or it would not be to touchy in the tuning. I plug my long wire aerial into the loop antenna's connector jack, then couple the loop to my receiver. It gets a better signal than just the loop.

[@rfburns3472]

Hey what a good idea Tom. I am going to try that.

Where can I find that surplus aviation radio? Thanks.

[@rfburns3472]

I purchased mine on eBay. The AM broadcast band radios are a bit rare, but they come up every now and then for auction.

Coul you demonstrate using it to notch out a signal?

[@rfburns3472]

Unfortunately it doesn’t work as a notch filter. it’s more like a tunable bandpass filter that covers 550 to 1700 kHz.

[@patrickwall8517]

Yes, loop antennas do tend to be less noisy than wire antennas.

[@rfburns3472]

Agreed

[@porkyfedwell]

I find that the loop doesn’t work with modern DSP AM radios, for some reason.
