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

Works fine and a reasonably inexpensive route into H1 radio astronomy. This is my second purchase which I use for live public demonstrations of galactic arm movement.

Like other Nooelec products that I have purchased, this LANA amplifier is well made and works as stated. You do have to filter out any other interference, like 14.5kW Radio Amor 100.3 FM, or you will end up amplifying interference as well as your signal. However, using the Nooelec broadcast FM filter, I am able to get many more signals in the 1-2GHz range. I use this amp with an SDR Play 1A and I use its bias-T to power the amp. Powering it this way, I do not need to put a DC block in line with the receiver. If you power the amp through the micro USB, you should get the Nooelec DC block or another brands DC block. The amplification range is from 20MHz to 4GHz, so it does nothing for HF signals. I found the amp to be low noise and have low insertion loss. The 85mA low power consumption makes it ideal for the SDR Play. Some reviews said that the amp does not work, but keep in mind that the LED power light should be facing your receiver or you will only see noise and think the LANA does work. This is a well made, general purpose RF amp. I like Nooelec and their well made, high value products with cool names. Get one, it's fun to play with.

I purchased this to use with a scanner with an attic mounted antenna and long feeder run. The low Noise Figure and decent gain of the LNA made a big difference to reception, for example I'm now able to pickup the control tower at a local airport where previously I could only receive aircraft that were airborne. The device is very well made with an extruded case housing a very nice PCB with the RF electronics inside another screened enclosure. There are options to power feed the device using DC via the coax on the Output connector using an external Bias-Tee or it can be powered via USB connector from a local PSU. But be aware then when you use the USB connector the DC voltage is fed back down the coax which could potentially damage a connected receiver, so when using with a local PSU via USB a coaxial DC block should be used on the Output side. This isn't a product deficiency and it's clear from the spec sheet that it works this way, but it is something to be aware of - I only realized it because the power LED went out when I connected the feeder down the scanner.

Dose not work. It adds noise to the signal making it even worse than without. The first one I had the bulkhead connectors were loose so I tightened them and one broke off the PC board.

Unit seemed to work well. However, the status/ON light seemed to have stopped working after a few weeks. Seemed to still work though. Returned it for that reason.

I own several small radios and SDR dongles that have always been just OK. What a difference one little amp can to to their performance! I was pulling in stations on bands that looked dead but had dozens of signals with this on! I really appreciate the T-power capability as my new Malahit DSP2 has the ability to power this amp directly through the antenna port. Simply enabling it on the radio's menu brings it to life and instantly signals appear! Performance for the price can't be beat! The metal case is sturdy and shiels the internal circuitry from nearby interference. I highly recommend this - I think you'll be impressed!

Helped increase my ADS-B range by almost 75nm in my case and reduced gain on my receiver. Was a very nice addition to my feeder setup.

I bought a few of these. One has a flaky USB-C power connector. On another two, the LED indicator lights when it wants to. Otherwise it has lower noise than some other (much cheaper) LNA's.

Je suis ravie et étonné du résultat que j'obtiens avec cette amplificateur de chez nooelec je connais bien la marque je sais qu'ils font des produits de haute qualité au dessus de beaucoup de fabriquant j'ai une clé SDR la Smartee qui marche à merveille de chez eux je voulais un amplificateur pour mon hack rf pour améliorer la sensibilité vu l'endroit où je suis placé je l'ai testé dans des conditions comme on peut le voir sur cette petite vidéo qui ne sont vraiment pas favorables à recevoir de l'ADSB surtout dans une zone militaire, j'ai fait exprès en plus de tester à l'intérieur du logement qui est un bunker à onde avec une petite antenne d'un pocket Kenwood thf7 voilà le résultat, c'est tout simplement inimaginable Chez moi alors à l'extérieur ce n'est plus le même appareil je l'utilise sur un hack rf , j'ai fait le test sur ma petite clé SDR aussi est avec elle justement qui marche très très bien la smartee que je recommande vraiment et le test c'est montré à la limite de l'exploitable tellement je reçois de signaux et de signaux venant de pays du Maghreb de l'Afrique c'est impressionnant j'ai l'impression qu'ils sont directement chez moi donc sur la clé nooelec je dirais que c'est beaucoup trop où il faut travailler avec des filtres et autres pour avoir un peu moins de sensibilité avoir de meilleurs résultats que ce que j'ai eu qui seront monstrueux donc avec certitude je peux confirmer après de nombreuses heures de test que l' ampli remplit vraiment très très bien son rôle encore une fois c'est une marque que l'on paye un petit peu plus chère mais on sait où on met notre argent et la qualité de fabrication et exceptionnelle je ne peux que vous le conseiller je ne sais pas s'il y a d'autres personnes qui l'utilisent sur le hacke rf si vous avez ce type d'appareil c'est à avoir absolument ! Vous n'allez plus reconnaître votre appareil merci à Nooelec une fois de plus je ne suis pas sponsorisé par la marque pourtant j'aimerais bien tester leur produit en avant-première mais je ne peux que constater le résultat d'ailleurs sur divers test très sérieux que j'ai pu voir sur YouTube par des professionnels des techniciens qui teste différents matérielles ils sont tous unanime sur la qualité de cette amplificateur vous savez que tout est respecté au niveau des fréquences de travail il n'y a pas de surenchère c'est pile-poil ce qu'ils annoncent et je dirais même mieux ils sont modeste car ils disent que l'ampli travaille de 25 MHz jusqu'à 6 ghz alors qu'elle peut monter jusqu'à 8 GHz le travail et apparemment relativement propre au-delà de ce qui est annoncé Idem pour la clé sdr qui dépasse allègrement les 2.5 GHz je ne suis jamais déçu de cette marque et merci Amazon pour la rapidité de livraison tout est parfait.

Non riuscivo a farlo funzionare in quanto la tensione di 5 Volts è ,per il mio sistema , eccessiva. L'ho ridotta ad 1 solo volt con un bias T esterno riducendo il guadagno. Se salgo verso la tensione di 5 volts il ricevitore diventa sordo con tantissimo rumore. Antenna discone Diamond D3000 , LNA Nooelec Lana, 10m Messi e Paoloni 7 , SDRPlay 2 ch.A e software SDRV3 Console. Molto soddisfatto per la sensibilità ma sopratutto per il rapporto segnale rumore. E' consigliabile piazzare l' lna subito dopo l'antenna.

Spodziewałem się obłej Lany z wejściem zasilania mini USB, a tu przyszła kanciasta z dziurką na wtyk USB-C - ewidentnie nowa wersja, o której w ogóle nie słyszałem. Do tego porządny giętki półmetrowy przewód zasilania z wtykiem USB-C, adapter do typowego okrągłego wtyku od zasilacza i adapter SMAm > SMAm. Pierwszy, szybki test wykazał, że wzmacniacz rzeczywiście jest niskoszumny :), a na konkretniejsze wnioski przyjdzie czas, gdy dotrze do mnie filtr Flamingo+.

特性をnanoVNAで測定してみました ゲインは10dB程度で低めに出ていますが周波数特性は特に低周波数側は 3MHz程度まで使えそうです（短波帯の受信での確認はしていません） 実際の受信は144MHzのアマ無線、FM放送波、ADS-Bの受信でしか確認していませんが何れも良好です ダイナミックレンジが広いようで広帯域のアンテナを使った場合でも特にフィルタなしでも受信が改善されるのは良いですね

I have been using my SDR (Software Defined Radio) RSPdx, with a Wide-Band Moonraker Discone Aerial and JIM M-75 GaAs Low Noise Pre-Amp combo. My SDR covers frequencies between 1KHz – 2GHz, whilst the Discone and M-75 each cover, more or less the same range of 20MHz – 2GHz. This arrangement has produced good results. The M-75, with Variable Gain, is connected at the receiver end of my 15m Down-Feed RG58 Coaxial cable. Due to Signal Quality degradation through coaxial cable, it seems the Best Practice is to amplify the Aerial Signal at the Aerial end rather than the Receiver end. Because of this, I decided to try the NooElec Active Wide-Band 20MHz-4GHz LaNA (Ultra-Low Noise Pre-Amp). The Build Quality of the NooElec LaNA is Very Good as is its cosmetic appearance. As the LaNA is an Active device, it requires power, which is derived from my SDR’s software activated 5v Bias-Tee feature. Obviously, the M-75 and LaNA cannot be used together, due to the way Bias-Tee operates. However, this really doesn’t matter, as the NooElec LaNA does a really great job, boosting the Gain of Received Signals. That said, the Gain is considerably more than I expected, requiring my SDR Software Gain levels to be reduced for certain Bands such as DAB. The NooElec LaNA with SMA Male-Male coupler, with power provided by my RSPdx Aerial-B Bias-Tee, which has worked perfectly over the last 5 weeks, does what it’s supposed to do and is now a permanent feature of my SDR-Discone set-up. Although it is slightly more expensive than some other brands, I think its Build Quality and Looks, as well as the USB, DC and Bias-Tee Power options, probably justify this. For all the reason above, I really do like this Device and feel it deserves 5 Stars.
