The amplifier works perfectly with my loop antenna. I don't want to be without it anymore.

I bought this amplifier and am satisfied with its performance for both my RTLSDR and my Grundig Satellit 750 receiver. It appears to have a gain of 30 dB based upon its performance. I am writing a review article about this for my site Radio Wavelengths https://radiowavelengths.wordpress.com/ Furthermore, the associated Blue Donut Loop Antenna is what I am using this with, which you can find here at Banggood. The loop antenna works perfectly, although small, it is the best antenna I have now.

Works like a charm on top of my Quansheng k5(8) with a rubber duck antenna, Cheers :)

Works fine with a long wire ant and telescopic ant, not much of a improvement on a receiving Loop. Great value for the money, would buy again.

For such a small unit works great as good as my $90 AUD unit
