Wow! just wow!!
Bought it thinking thinking at this price if it don't work no big deal. Wow!! did it ever work.. In combo with a DIY long wire antenna Full bars on stations I couldn't hear and still can't without it. Great product.

Don't purchase this item. Wastage of money.

This LNA works as a huge attenuator instead of an amplifier as you can see in the comparison between WITH and WITHOUT the LNA in the pictures.I tried it with my RTL-SDR dongle first then FT-736R and FT-1000MP Mark-V from LW to 1.2GHz.If you are planning to buy one of these, think again.

prodotto molto valido preamplificatore d'antenna per le HF validissimo.
Prodotto usato come preamplificatore HF in un ricevitore FT-277 che normalmente non ha di preamplificazione. Segnali passano da 3 a 8 e basso rumore di fondo. Consigliato. Pilotato con alimentazione tramite potenziometro da 500 ohm in serie è possibile variare il livello di amplificazione ma non solo, diminuendo la tensione si ottiene una attenuazione del segnale in ingresso. In pratica variando la tensione si passa in continuità da amplificatore ad attestature. Occhio alla schermatura, è facile ottenere inneschi a motivo dell'elevato fattore di amplificazione. Io l'ho chiuso completamente in una scatoletta di lamierino completamente saldata. Allego toto del montaggio e della scatoletta variatore di tensione.

AT LAST one that works
I've tried a few of these cheap Chinese preamps and most suck, but this one boosts the signal (and noise of course) from both tuned shielded receive loops and untuned loops on topband and 80m, allowing me to phase receive antennas against my main transmit antenna (3/8 wave inverted Ls on those bands) and null out local interference - or to phase receive antennas against each other. Obviously they work better right by the loop. I used a 12v supply with them. The actual noise figure of the amp itself isn't something I can test.
