Just got mine Friday. It's a $30 antenna. It is not something I would put outside unless inside a weatherproof enclosure. I tried it for a bit connected directly to a RSP1A to exclude the potential for USB power noise from the power injector. Hanging in a closet on the second floor, it picks up all the noise just like any other antenna indoors at this locale.
See comparison with Sigma 18' HF vertical and a $600 widebanded Belar LP-1A shielded amplified MW loop. Ignore the S meter as it is showing what the radio is actually tuned to, so we'll use the scale on the left as reference. Radio is the RSP1A with the AM/FM notch filter ON because of 1350kHz station about a mile away.
If you look at signal peaks, on MW you can see it is about 6dB down on local station 1350kHz, and about 11dB down at 7490kHz compared to the vertical, and to give a fair comparison on MW, only about 6dB down at 1350kHz from the commercial MW Belar loop located in the same room, both oriented E/W.
