Our take on the NESDR SMArTee v2

The NESDR SMArTee v2 is a USB software-defined radio receiver built on the RTL2832U demodulator and R820T2 tuner, the standard RTL-SDR chipset. Its distinguishing feature is an always-on bias tee, which feeds power up the coax to an active antenna or inline LNA without a separate injector. It comes in a brushed aluminum case and is aimed at hobbyists receiving ADS-B, weather satellites, public-safety and amateur signals. The best new price is $54.95 at Nooelec as of November 5, 2026, with three stores listing it new.

Best forRTL-SDR beginners who want a bias tee built inADS-B and satellite reception with an active antennaUsers who want a metal-cased dongle that runs coolListeners on Android, iOS or iPadOS with a USB adapter
Pros
  • Always-on bias tee powers an LNA or active antenna over the coax
  • Metal aluminum case shields and dissipates heat better than plastic dongles
  • R820T2 tuner covers roughly 24 MHz to 1.7 GHz with the usual RTL-SDR software
  • Low power draw, about 10 mA less than comparable designs
  • Works with common SDR software on Windows, Linux, macOS, Android and iOS
Cons
  • Bias tee cannot be switched off in software, so it can damage antennas that must not see DC
  • Needs an OTG or Lightning adapter on phones and tablets
  • No TCXO, so frequency drifts slightly with temperature on narrowband signals
  • Only SMA input; antennas with other connectors need an adapter

Owners treat the SMArTee v2 as a solid, well-built RTL-SDR with a convenient built-in bias tee. The metal case and stable reception get consistent praise. The main complaints are the always-on bias tee and the lack of a temperature-compensated oscillator.

What people mention
  • Bias teeMixedOwners like powering an LNA over the coax but note it is always on and cannot be switched off.
  • BuildPraisedThe brushed aluminum case is described as sturdy and better at shedding heat than plastic shells.
  • Frequency stabilityCriticisedWithout a TCXO, users report slight drift that matters on narrowband signals.
  • SetupMixedIt works with standard SDR software, but phone and tablet use needs an OTG or Lightning adapter.
  • ReceptionPraisedBuyers report clean reception for the price on ADS-B and general scanning.

Questions and answers

Is the bias tee always on?
Yes. The SMArTee v2 has an always-on bias tee that sends DC power up the SMA input. Do not connect an antenna or device that cannot take DC on the center pin.
What frequency range does it cover?
The R820T2 tuner tunes roughly 24 MHz to 1.7 GHz. Reception below that needs a different tuner or an upconverter.
Does it work with a phone or tablet?
Yes, with an OTG adapter on Android and a Lightning or USB-C adapter on iOS and iPadOS. You also need a compatible SDR app.
How is it different from a basic RTL-SDR dongle?
The main additions are the always-on bias tee and the aluminum case. The chipset is the same RTL2832U and R820T2 found in cheaper dongles.
Does it include an antenna?
No. The package is the receiver itself, so you need an SMA antenna or an adapter for your own.
When is it cheapest?
The best new price is $54.95 at Nooelec as of November 5, 2026. Check the price history for whether that is below its usual range.
Where is the NESDR SMArTee v2 cheapest?
