## Overview

The NooElec LaNA is a high-performance, ultra-low-noise amplifier module designed for software defined radio enthusiasts and professionals. Covering an expansive 20MHz to 4GHz frequency range, it offers superior gain, low noise figure, and excellent linearity housed in a durable aluminum enclosure with EMI and ESD protection. Power it flexibly via Bias-Tee, USB, or DC input, making it compatible with a wide range of SDR setups. Made in North America and backed by a 2-year warranty, LaNA is the go-to choice for boosting signal clarity and strength in demanding RF environments.

## Description

FOR FULL SPECIFICATIONS AND DETAILS, PLEASE REVIEW THE PRODUCT PAGE AT NOOELEC.COMLaNA is a very high performance, wideband LNA module designed for general purpose SDR applications. Each module allows for 3 different power options, but you should only power with one option at any given time! The recommended power input through the SMA output port (for bias-tee capable SDRs like the NESDR SMArTee XTR) is 3V-5V DC. Alternatively, if you don't have a bias-tee capable SDR, you can use the external power options--the microUSB port, or DC barrel connector via the included DC to microUSB adapter. The recommended external power input is 3.3V-5.5V DC. Though there is protection circuitry on LaNA for overvoltage conditions--and voltages of up to 12V DC should still work and will not damage the device--it is not recommended for long-term usage. Kindly note that damage resulting from overvoltage conditions would not be covered under the standard 2 year warranty. Each LaNA module has an internal EMI shield to protect the sensitive circuitry from external interference and is fully ESD-protected.

Review: Very good. Boosts signal nicely - I have a NESDR Smartee and it powers this lovely. It adds a decent amount of extra signal strength. 20db approx. I will be experimenting by adding a 20db attenuator based on a YouTube video showing further clarity improvements to drop the noise floor while helping boost signals. But as for this product as-is, it is good and works well.
Review: NooElec LaNA Wide-Band 20MHz – 4GHz - 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.

## Features

- A wideband (20MHz - 4GHz), high-performance, general purpose LNA module installed in a quality aluminum enclosure
- Higher gain, lower noise figure, lower power consumption and better linearity than modules based on SPF5189Z and similar LNA MMICs
- Can be powered through bias tee (3.3V-5V), USB, or DC power with the included adapter. A free male SMA to male SMA connector is also included
- Made in North America. 2 year warranty!
- NOTE: Some SDRs will require a DC block between the LNA and SDR if utilizing the external power options. For more information review the product page or datasheet: https://www.nooelec.com/datasheets/100812

## Questions & Answers

**Q: If i purchase this amplifier will i require a dc block with the airnav flightstick, powering the amplifier with usb "external power" (no bias tee)**
A: I would say yes, Airspy R2 wants one and yours is broadly similar

**Q: May need dc block when using usb.. does that mean it (cool!) adds bias-tee?**
A: I used it with USB and never need led a dc block. It wont add bias-tee, only the sdr sticks do

**Q: Doesnt rtl-sdr already have 40 db variable gain,  how does this differ?**
A: Hi!  The noise figure of a system is dominated by the first LNA in a chain.  This LNA has a noise figure well under 1dB, while an RTL-SDR has a noise figure above 6dB.  This is a massive difference and so this LNA would give you a much better SNR while still allowing you to increase the overall gain even further with the built in LNA of the RTL-SDR.

Hope this helps!

**Q: Is it okay to transmit through this too?**
A: No

### ⭐ One to avoid.
*by H***9 on 19 July 2025*

It's a good amp. But, it does not power up on bias T from SDRplay RSPdx R2. Need to use powerbank or USB power adapter. EDIT... Died completely after a couple of months. Power light started to flicker then just went out. No longer amplifying.
