A 978 MHz UAT receiver can receive FIS-B weather in the United States; 1090ES reception covers a different ADS-B link. Dual-band receivers support both links.
Portable ADS-B receivers are an ADS-B In source for compatible displays. Their band capability affects which broadcasts they can receive, and the aircraft’s installed equipment remains a separate question.
| Receiver | What it can receive | Main consideration |
|---|---|---|
| 978 MHz UAT only | UAT broadcasts, including FIS-B in the United States | Does not receive 1090ES transmissions |
| 1090ES only | 1090 MHz extended squitter broadcasts | Does not receive FIS-B directly |
| Dual-band | UAT and 1090ES broadcasts | Costs and power needs vary by device |
The FAA describes FIS-B as a broadcast on the 978 MHz UAT link. Therefore, a 1090ES-only portable receiver does not receive FIS-B directly. Traffic and weather display availability also depends on the receiver, EFB application, antenna placement and coverage. A dual-band model can receive both links, but the display must support the data and the device must be configured correctly.
Do not confuse ADS-B In reception with ADS-B Out compliance. A portable receiver provides information to a cockpit display; it does not make an aircraft’s installed equipment compliant with an equipage requirement. Check the FAA rules and the aircraft installation for the specific operation.
For buyers who usually fly within UAT coverage and mainly want FIS-B, a UAT receiver may fit the use case. Pilots who want to receive both link types can compare dual-band models. Confirm display compatibility, battery runtime from the maker’s specifications, antenna placement and mounting. The portable ADS-B receiver guide covers selection; the EFB guide explains the tablet and app side.

Common questions
Can a 1090ES-only receiver receive FIS-B?
FAA guidance says FIS-B is delivered on the 978 MHz UAT link, so a 1090ES-only receiver does not receive FIS-B directly.
What does a dual-band ADS-B receiver add?
It can receive both 978 MHz UAT and 1090ES broadcasts, subject to device and application support.
Does a portable receiver replace required ADS-B Out?
No. A portable ADS-B In receiver is a traffic or weather display input, not a substitute for required ADS-B Out equipment.
