Nooelec LaNA Barebones - Ultra Low-Noise Amplifier (LNA) Module for RF & Software Defined Radio (SDR). Wideband and Linear 20MHz-4000MHz Frequency Capability with Bias Tee & USB Power Options

Does what it says

Purchased to improve NOAA reception . Using with SDRPLAY 1A and sdruno. First off, the bias t output from sdrplay wasn't enough to run the LNA. led flashed once and went off, so I used usb supply and it powered on. Initially when trying to receive signals I had nothing but noise.. But after reducing the RF gain in sdruno down to minimum and then notching up a little at a time I found a happy medium. As you can see from pictures. This was using a J pole vertical antenna tuned for 2 metres..in the attic! I may consider disconnecting the Led and see if this brings the current requirement down enough for the sdrplay to run it. I have yet to try on UHF. Overall a good device for the price.

Connects easily via adapters to other SDRs. Mine is currently attached to the SDR Mini V2, and is used for receiving 2m amateur signals and also DVB-T through VLC. In order to minimise the strain on what appear to be quite delicate connectors I designed and printed a tray to sit it on. It would be most beneficial placed at the base of the antenna with power supplied through the Bias Tee, rather than USB.

Got this lna for my Noaa setup. It works very well got around 7 degrees of a satellite pass more and the strength of the signal improved. I'm using a home built dual cross antenna 30 m feed line and a sdrplay rsp1a. The antenna is very low 1.5m above ground. Last picture is a Meteor m2 daytime.

Worked fine for a while then just packed up after the return date. Get one of the cheaper ones, half price.

Sdr radio essential

Does what it says on the tin, doesn't stop the signal showing up in waterfalls but the noise is all gone

Absolutely amazing products yet again from nooelec always top quality work this is the second item I bought from them and I am 2 times happy

Questo LNA è la versione senza case dell'articolo ASIN: B07XNLJ9X2. Appena installato l'articolo nonostante l'antenna che non sia delle migliori, sono riuscito a ricevere segnali che prima non erano minimamente mostrati, anche cose vicine ai 27MHz con l'antenna originale dell'SDR che sarà al massimo 60-80cm, non la ho mai misurata. Ovviamente con una chiavetta basata su RTL2832U è necessario un Notch per le frequenze della radio FM (88-108) per via di rumore e vari problemi che se no si vanno a generare sulle frequenze sotto a 80MHz. Purtroppo non posso confrontarlo con prodotti della concorrenza perché possiedo solo questo ma per ora, sembra un OTTIMO articolo. Già solo per il fatto che la sezione di amplificazione è chiusa dentro un piccolo shield RF. Purtroppo arriva senza adattatori SMA ma costano pochissimo.

Utilisation: pré-ampli antenne suivi de10 m de cable coaxial. Résultat conforme a mon attente: ampli conforme aux spécifications. A savoir: tel que livre l'alimentation a lieu par le coaxial de sortie. La protection contre les décharges électrostatiques est un avantage certain, mais il reste recommande de prendre les mesures de précautions usuelles.

After my original RTL-SDR LNA broke, I needed a new LNA a.s.a.p. Firstly I ordered the SAWBird NOAA but that LNA did nothing but increase the general noise floor and didn't increase NOAA-reception. I then placed this LNA instead, powered over Bias T, and I actually think it might perform even better than the RTL-SDR LNA. I'm actually thinking of buying a 2nd Nooelec Lana because even for ADS-B the reception is marvellous with an off-tune antenna.

En las recepciones de los Noaa he conseguido recibir la señal ya a los 7º y comenzar a grabar a los 10º, como dijo otro usuario es muy importante experimentar con tu SDR, en mi caso el SDRpPlay me costo ajustar correctamente la ganancia de RF, con sólo 3 y 4 clicks es suficiente porque al principio saturaba tanto que recibia menos señal con el LNA instalado que con el quitado, algo estaba haciendo algo mal. Por lo tanto para mi cometido que es satelites meteorologicos estoy satisfecho. Gracias!
