Where to Buy RTL-SDR RTL2832U DVB-T Tuner Dongles
At RTL-SDR.com we sell significantly improved premium RTL-SDR dongles but keep our profits low and offering free aircraft in order to maintain low retail pricing. Nosotros strongly believe that our V3 dongles are currently the all-time 'bang for your buck' RTL-SDR dongles available on the market. Please see the V3 features pdf datasheet here for total data on the improvements made, and our V3 users guide for data on using special features of our dongle. If you are new to RTL-SDR check out our virtually folio commencement. Briefly, our dongles come with the following improvements:
- <1 PPM temperature compensated oscillator (TCXO) – Accurate tuning and near zero temperature drift (2 PPM max. initial outset, 0.5-i PPM temperature drift)
- SMA female antenna port – Generic dongles apply the less mutual MCX or PAL antenna ports. SMA is more common, so more than adapters and antennas are available for it. It is also more durable and has lower RF insertion losses.
- 4.5V USB powered bias tee - This allows the RTL-SDR to ability low dissonance amplifiers (like the LNA4ALL, HABAMP, RTL-SDR Blog ADS-B LNA) and active antennas through the coax cable. Tin can be enabled in software (see V3 users guide).
- HF Direct Sampling Manner- Heed to 500 kHz - 24 MHz with directly sampling. Simply connect an HF antenna to the SMA port, and choose the Q-branch manner. There is a built in 25 MHz low pass filter, but additional HF filters may be required for optimal operation (east.one thousand. to attenuate potent MW AM).
- Aluminium case and passive cooling- These units come stock with an aluminium case and passive cooling via a silicon thermal pad. This stops reception failing due to rut when used above ~1.2 GHz.
- Improved Antennas - We provide an excellent dipole antenna starter kit for newbies. Use the included mounts and extension cable to mount the dipole in expert position for optimal reception. Receives terrestrial and VHF satellite signals.
- Various additional improvements compared to other RTL-SDRs– R820T2 tuner, college quality passive components, a choke on the USB line to reduce USB noise, a much improved PCB design for significantly less internal spurs and noise, various break-out pads, improved ESD protection, boosted bypass capacitors and ferrite power line chokes, improved front end matching circuit, a modified power design for improved long term reliability, and a improve LDO.

Recommended accessories from other sellers
Note that some of the links below are chapter links which assistance back up the costs involved with the running of this blog. However, all the products listed are what we really exercise recommend regardless.
Antennas
Probably the most of import part of a radio organization is the antenna. At that place is no one size fits all antenna, every different design will have a trade off. For instance, broad band antennas can receive more frequencies, but will have less gain at any one particular frequency. If you desire to receive everything so get a broad band antenna. If you want to receive one frequency with optimal reception, detect a tuned narrow ring antenna.
Discone Antenna
Discones are wideband antennas. This makes them platonic for the RTL-SDR equally using a Discone will allow you to receive at almost whatever frequency with decent performance.
FlightAware ADS-B Antenna
A 1090 MHz ADS-B antenna from FlightAware. Is weather proofed and has five dB of gain. Uses an N-blazon antenna connector. Encounter our review post for more than data.
Upconverters
The lowest frequency an RTL-SDR can comfortably tune to is about 24 MHz. An upconverter allows you to employ your RTL-SDR on HF frequencies which are betwixt 0 - 30 MHz. They piece of work by shifting frequencies betwixt 0 - 30 MHz "up" by a fixed amount into a frequency range that is receivable by the RTL-SDR.
SpyVerter Upconverter
Currently we recommend the SpyVerter as the upconverter of choice. Although it was designed to exist used with the Airspy, it works perfectly with the RTL-SDR. Information technology uses a 120 MHz oscillator, has first-class filtering and can be powered via USB cable or via the bias-tee on our RTL-SDR Blog dongles. The SpyVerter uses an innovative new compages that reduces overloading, has better SNR than other options and tin can operate all the fashion downwardly to DC.
With the above performance and features, the included metal instance and adapters and at a like or even lower price compared to other upconverters nosotros retrieve this one is the all-time value. See our review post for more information.
SV1AFN Upconverter
An alternative to the SpyVerter is the upconverter designed by SV1AFN.
It based on the ADE-1 mixer chip, uses a 200 MHz oscillator, has practiced filtering and works almost down to DC.
Ham-It-Up Upconverter
Another recommended choice is the Ham-It-Up Upconverter.
This one like the SV1AFN is also based on the ADE-1 mixer, merely uses 125 MHz oscillator and is based on an open source design. In that location is also a metallic case available on Amazon and eBay. Nevertheless, currently we would recommend the SpyVerter or SV1AFN over this option.
RF Filters
RF filters connect between your antenna and RTL-SDR dongle. They help to significantly reduce out of band interference and noise which is very helpful when trying to improve signal strength.
118 - 138 MHz Air Band Bandpass Filter
If you are monitoring ACARS or air traffic signals so yous may desire an air band bandpass filter if you find that you lot have lots of interference from nearby stations such every bit FM broadcasts and Pagers.
FlightAware ADS-B Filter
FlightAware sell a very affordable ADS-B ring pass filter. Many users have reported significantly improved reception when they started using this filter. This is probably the best filter to get if y'all are interested in ADS-B. See our review mail service for more than information.
ADS-B HABamp LNA + Filter Combo
Nosotros besides highly recommend the ADS-B HABAmp for receiving ADS-B signals. This is a filter + LNA combination that works very well and will significantly improve ADS-B performance.
We've tested these ourselves with the activatable bias tee in our units and found them to definitely work very well.
Multi HF Bandpass Filter
This product is slap-up for if yous are using an upconverter together with your RTL-SDR, or other SDR. Contains seven ring pass filters that range from 1.six - 2.5 MHz, two.v - 4.vii MHz, 4.7 - 7.5 MHz, 7.5 - 14.five MHz, xiv.v - 21.5 MHz, 21.5 - 33 MHz and 33 - 56 MHz.
Low Racket Amplifiers
If yous have long runs of coax cable then a depression dissonance amplifier (LNA) tin can help to significantly improve your reception. Coax cable is lossy and the longer it is the more your received signal is attenuated. By calculation an LNA nigh the antenna this loss can be reduced.
LNA4ALL
The LNA4ALL is a very affordable wide band low noise amplifier that is very normally used with the RTL-SDR. Has the ability to be powered externally from whatever voltage between 6V - 9V, or with a simple modification with 3V - 5V in bias tee fashion.
Nosotros accept tested the LNA4ALL in bias tee mode with the activatable bias tee in our units and found it to piece of work well.
Other LNA's
There are also several low noise amplifier circuits that can be found very cheaply for sale on eBay and most will do a good job. Unfortunately well-nigh don't provide a bias tee option similar the LNA4ALL or HABamp does. Currently we recommend LNA's based on the SPF5189Z chip as they accept wideband skillful performance, and are cheaply produced.
Other Accessories
Agile USB Extension Cable
Ideally yous want to get the RTL-SDR dongle as close to the antenna as possible. Normal USB cables have a length limit of about 5m before they stop working, but with an active USB cable this can exist extended up to x to 15 meters.
We recommend these Monoprice cables every bit they have been reported to work successfully with the RTL-SDR dongle.
RG6 Coaxial Cablevision
We recommend using RG6 coaxial cable for most links betwixt your antenna and RTL-SDR. RG6 is low loss cable and it is too very inexpensive considering it is used commercially with satellite Television installations.
RG6 is 75 Ohm cable. Note that the mismatch between 50 and 75 Ohm impedances is completely negligible for RX applications.
Clip on USB Ferrite Core
Noise and interference can sometimes be induced in the USB cablevision itself which can show upward in the RF spectrum. To finish this noise use clip on ferrite cores on the USB cable. These cores assistance to suppress unwanted currents in the USB shield.
Raspberry Pi 3
A Raspberry Pi is a credit card sized computer that runs Linux, or even Windows. With it you can connect an RTL-SDR, run a server, then remotely ship a betoken or processed data such every bit ADS-B aircraft locations back via WiFi or Ethernet cablevision.
USB OTG Cable
A USB on-the-go (OTG) cablevision is required to use the RTL-SDR on Android phones with software like SDR Touch and Wavesink. We recommend trying to find cables that come with power plugs so that you tin employ it with a power pack. Using an RTL-SDR tin increase CPU usage which tin can rapidly drain a mobiles battery.
nine:1 Balun
If you are using a long wire or random wire antenna with a HF modded RTL-SDR or an upconverter you should use a nine:one impedance transformer to get good SWR.
At that place are also several other alternatives available on eBay that utilise a larger fe core.
Wideband Noise Source
A wideband racket source can exist used together with an RTL-SDR dongle to perform measurements on filters and to measure the SWR of an antenna.
See our tutorial here for more than data.
Recommended alternative SDRs
Airspy
Airspy SDRs have loftier functioning RX capabilities with mid tier pricing. Their units really shine when used in tough RF environments, such as in RF environments with strong and weak signals together. The Airspy is an fantabulous upgrade from an RTL-SDR dongle.
Encounter our review post for a comprehensive comparison between the Airspy, SDRplay RSP and HackRF.
SDRplay RSP
Some other practiced mid range SDR is the SDRplay RSP line of receivers. These SDRs are nifty value for the price and tin receive HF frequencies without an upconverter. Previous iterations were backside the Airspy in terms of overall performance, but the RSP1A and newer models are on par.
Come across our review post for a comprehensive comparison between the Airspy, SDRplay RSP1 and HackRF.
HackRF One
The HackRF One is a relatively low toll TX/RX capable SDR. It is designed for radio experimenters and information technology has a very wide band frequency range from 1 MHz to 6 GHz, and a wide bandwidth of up to 20 MHz and an eight-Bit ADC. It is probably the virtually versatile SDR that exists at the moment, only in a compromise it does not take the best quality RX or TX operation. Thus it is perfect for experiments like opposite technology and testing RF devices, but it is not intended to exist used equally a commercial radio or ham radio.
