Does what it says.
I used this right at the antenna to cut losses in the feed line for HF reception. It works great. Used on 10m to 40m.

Very nice amplifiers
This is exactly what I needed for my active antenna project!

Works as expected. An enclosure would have been nice.
The media could not be loaded. See the attached video for Bias-T in action with a YouLoop antenna + SDRPlay RSPdx using SDR Console. Of course without power it acts like an attenuator. Wish it had an enclosure.

It didn't work as a preamp on my radios
It didn't work as a preamp on my radios. there was a slight gain but not enough to qualify as a preamp.

Seems to work fine.
Observed noise not reduced in my application. Must be internal.

High gain but not adjustable.
Very high gain but with a high S/N noise factor.

Hrm..ok
No difference and from testing the reception was cast worse. I regret the purchase.

Awesome LNA
This LNA rocks, with bias-t power my RTLSDR picks up way more signals than it does normally. With a 9:1 unun and 60' of wire, I can hear down to about 10Khz.

Rauscharmer Vorverstärker
Das LNA-Barebone ist bei mir an einer 1-Meter-Rahmenantenne via Balun angeschlossen.Es ist rauscharm wie beschrieben, ich vergleiche die SNR-Werte am SDR Play "RSP2 Pro" und SDR Uno-Software mit einem Passiv-Rahmen 70 cm durch direktes Umschalten am SDR Play und kann keinen signifikanten Rauschanstieg feststellen.Klar bringt ein LNA immer etwas Noise in die Signalkette, im Vergleich zum passiven Loop ist es aber wirklich nicht viel.Sehr schön die Möglichkeit der LNA-Speisung via USB, Steckkontakten und BIAS-Tee.Der RSP2 Pro gibt an "ANT B" ja knapp 5 Volt aus, und die speisen den LNA übers Kabel ohne weitere Bauteile.Somit entfällt eine Störquelle durch schlecht gefilterte Netzteile oder störbehaftete USB-Speisung. Das Signal ist klar und rein und ohne Artefakte durch evtl. HF-Einstreuung über Schaltnetzteil.Für alle, die den BIAS-Tee nicht nutzen können oder wollen:Unbedingt eine USB-Powerbank zum Speisen des LNA verwenden, das ist die einzige Möglichkeit, über die Versorgungsspannung keine Störungen herein zu bringen.

Funziona molto bene
Recentemente ho acquistato uno splitter d'antenna passivo con 3 uscite, perdita dichiarata 8dB; ho pensato quindi di aggiungere questo LaNA per compensare la perdita, devo dire che funziona molto bene, sono soddisfatto.L'unica pecca che trovo è la mancanza del contenitore, come ha il LaNA per V/UHF.

RF Pre-amp
Very pleased with this amp. Just what I needed to receive the WLG airport radio channels. Very prompt delivery. Top line service from Amazon again.
