GA800 Active Shortwave Radio Loop Antennawith BNC Cable 10KHz-159MHz Portable HF Receiving Antenna for Ham Radio

didn't really make much difference when turned on

Precio muy elevado por el servicio que provee

This unit may have a manufacturing flaw. The reception is extremely poor.

Really nice compact little Antenna and it came with everything you might need to install it close to or far away from the receiver, but I didn’t find it improved the reception that much so I returned it.

I restore vintage tube radios from the 30s through the early 60s, many with shortwave requiring external antenna or similar long wire setups. Purchased this to use with some various radios i have restored to use in my home as show pieces that work fine on even a plain wire antenna of minimum length. Just wanted something that I could use to show to folks how the sets worked without an elaborate setup or ugly wire just strung up, not trying for extreme DX etc. Well, it just injects noise...no real reception except what you could expect from 2 feet of copper wire attached. Took it to my shop and tested the loop with various modulated signals at different signal strengths from signal generator and measured the output with my oscilloscope and...zilch....just noise from the circuit.....it literally won't pass any usable RF thru the circuit...just noise all over the spectrum....maybe I got a clunkers but I've seen enough similar reviews that apparently it's a hit or miss product.....
