Dual Band ADS-B Traffic and Weather Receiver

The new dual band ADS-B receiver receives weather & traffic on both 978 MHz and 1090 MHz frequencies.

The dual band SV-ADSB-472 receives ADS-B traffic via 978 MHz (UAT) and 1090 MHz. In the US, it also receives free text and graphical weather from the FAA’s network of ADS-B ground stations. Unlike portable ADS-B receivers, you get FULL ADS-B and radar traffic when you pair this with our Mode-S transponder. The remote mounted receiver utilizes an externally mounted antenna for superior ADS-B reception.

Dual Band ADS-B Receiver


ADS-B Weather:Subscription-free weather displayed on SkyView, including NEXRAD radar, METARs and TAFS. Airport weather data can be displayed for nearest airports or for a specific airport identifier.
TFR Information: TFR NOTAMs are displayed graphically on the navigation map.

ADS-B Traffic: Receives ADS-B traffic targets with precise location, altitude, speed, and direction. Includes both traffic broadcast from other aircraft equipped with ADS-B UAT transmitters and data broadcast from ADS-B ground stations. For full FAA 2020 ADS-B mandate compliance, pair this receiver with Dynon’s SV-XPNDR-261 and SV-GPS-2020 modules for the industry’s most affordable ADS-B Out.

Antenna Information: The SV-ADSB-472 requires its own antenna; it cannot share the transponder's antenna. A UAT-specific antenna or a transponder antenna may be used with the SV-ADSB-472. Antennas available include (but are not limited to):

Dynon ADS-B Antenna (Recommended)

Rami AV-74 (TSO'd)

The ADS-B antenna must be installed at least two-feet from the transponder antenna.

Dimensions: The SV-ADSB-472 is approximately 2.79" x 4.10" x .97" in outside dimensions.
Weight: 0.3 lb. (0.12 kg)
Power: 0.05A @ 12V DC

The SV-ADS-472 is a dual band ADS-B receiver (UAT/978 MHz & 1090 MHz), while the SV-ADSB-470 receives only on UAT/978 MHz. This allows the SV-ADSB-472 to see aircraft equipped with 1090ES ADS-B Out equipment when outside the range of an ADS-B ground station. The SV-ADSB-472 is a drop-in replacement for the SV-ADSB-470, with identical wiring. Note that the SV-ADSB-472 is smaller, has different mounting dimensions, and the connectors are located differently than they are on the SV-ADSB-470.

No, the SV-ADSB-470 has been discontinued.

Yes. Dynon has an affordable trade-in program for SV-ADSB-470 customers that would like to upgrade to the SV-ADSB-472.

The SV-ADSB-470 and SV-ADSB-472 receive identical weather, as weather is only sent over 978 MHz, and both products receive on 978 MHz.

For traffic, the SV-ADSB-472 receives traffic via both ADS-B frequencies - UAT/978 MHz & 1090 MHz. The SV-ADSB-470 receives traffic via UAT/978 MHz only. While one might think this makes the SV-ADSB-472 superior, they are closer in capability than many realize.

Neither product (nor any other ADS-B receiver) can see aircraft that is are not equipped with ADS-B Out. Although more aircraft will equip as 2020 approaches, a sizeable percentage of the fleet will choose to not equip at all (they’ll need to avoid ADS-B rule airspace after 2020). The FAA’s ADS-B network of ground stations are designed to deal with this issue, and when your aircraft is talking to a ground station via ADS-B Out, both the SV-ADSB-470 and SV-ADSB-472 receive the same traffic information back. When you are ADS-B Out equipped, and are in a radar coverage area, the ADS-B ground stations relay all traffic targets that are around you. If you are in range of a ground station but not in a radar coverage area, the ground stations will still relay all other ADS-B Out equipped traffic. This means that whenever you within range of a ground station, you see all possible traffic with either receiver. The only time the SV-ADSB-272 (or any dual band receiver) has an advantage is when you are flying in an area that is not covered by an ADS-B ground station station. This is most likely to be the case in mountainous terrain, or very near the ground (the ADS-B system is designed to cover almost the entire US at 1800’, with coverage beginning much lower in most places). Even in this situation, the advantage of a dual band receiver is slight: In this case, the SV-ADSB-470 will see UAT equipped aircraft, while the SV-ADSB-472 will see both UAT and 1090ES equipped aircraft. However, NEITHER receiver will see aircraft that aren’t equipped with ADS-B Out. Because many aircraft - especially in remote areas - are not ADS-B equipped, and these are NEVER visible to any ADS-B receiver if you are not in range of a ground station. All of that said, if you’d like to upgrade your SV-ADSB-470 for an SV-ADSB-472, we do have a generous trade-in program available.
