I noticed that my update rate is not showing, so I went to test the antennas using ./rtl_test -d 0 and the response I get is "No supported devices found."

They are just standard mag mount whips with a strong magnet, but modified a bit so that the bottom plate has much better conductivity to the ground plane. That reduces radiation skew. Also with RG58 coax. ETA on selling the an...
