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

It has a really good noise figure. I compared it to other laboratory instruments in the front end of a high quality radio

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!

Works great. Used with my weather balloon tracking. Was -90 db , now -80 db with amp. USB powered

Works very well. Took off 1 star because the LED burned out but the amp still works fine.

I only used it a few times before it quit working. No power to the module, regardless of the cable I use. It worked great for the few times I used it, but definitely wish it would have lasted longer. Would recommend finding a different, more reliable option.

I used one temporarily with an outside installation for weak satellites and it worked great. I shielded it from the sun. I don't think it is really meant for that application but it worked and it worked quite well. It was powered from the Bias T in an RTL v4 dongle. The closer to the antenna you can place it, the better.

Sort of a long term review on this one. I have had this for several years now and it still works. Really nice solution to boost signal strength before going into an 8 way splitter for 8 Nooelec SDRs. Allows me go monitor over 55 EMS, Fire, local police (no Pa state police they are encrypted), GMRS, NOAA weather and P25 channels in my area all at the same time with some free software on my laptop. Just runs like a scanner with capability to decode digital. Even had a SDR arrive dead and after some trouble shooting sent me a replacement unit with little hassle.

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.

Ce produit est bien. Je l'ai utilisé avec ma clé SDR V.3 et un fil de cuivre de 4,25 m. Le LaNA, avec le Bias-T activé, nettoie tous les parasites et amplifie le signal. plus de grésillement !

If used for wide-band signal measurements; be sure to compensate for the frequency characteristic of this LNA by measuring that characteristic with the same equipment.

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.

Bought because of wideband coverage but not a true wideband amp. VHF High -- 136 to 200mhz, very little improvement UHF Commercial around 4560mhz, small improvement ADSB on 1090mhz improvement, but with a little noise.

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
