5 Options for ADS-B Receiver
Automatic Dependent Surveillance Broadcast (ADS B) is required equipment on most aircraft in controlled airspace. You have lots of options.

Check out some of our favorite options for ADS-B receivers. [Credit: FLYING Archive]
Editor’s note: The following article is not intended to be a ranking, but is only to serve as a list of possible options. As the saying goes, your mileage may vary.
The choice of ADS-B receivers comes down to the money a pilot wants to spend, whether the unit will be integrated with avionics in the instrument panel—or Foreflight or another app—and what additional bells and whistles (such as weather, music) the pilot seeks. As an aircraft owner, you can spend just enough to keep the aircraft ‘legal’ in the eyes of the FAA or you can spend more to have a higher level of functionality, meaning the ADS-B will do more than let ATC—and the other aircraft—know where you are and help you locate other aircraft in the sky with you.
The all-new Sentry Plus is loaded with safety features: subscription-free weather, dual band ADS-B traffic, backup attitude, and a carbon monoxide detector.

What Is an ADS-B Receiver?
ADS-B stands for automatic dependent surveillance broadcast, and an ADS-B receiver is surveillance technology that determines an aircraft position via satellite navigation or other sensors and periodically broadcasts it, enabling the aircraft to be tracked.
What Does an ADS-B Receiver Do?
An ADS-B receiver uses satellite navigation to determine aircraft position in three dimensions. A pilot using ADS-B will be able to locate other aircraft in the vicinity if they are equipped with ADS-B and see their location on their tablet.
Which Pilots Need ADS-B Receivers?
As of January 1, 2020, all aircraft operating over all 48 contiguous states, within airspace at or above FL100, excluding airspace from 2,500 ft agl are required to have ADS-B out. Basically, if the pilot flies in Class B or C airspace, ADS-B is required.
Requirements for Alaska and Hawaii are somewhat different; the Class E requirement is not in effect, though ADS-B is required at or above FL180 and at or below FL100, when operating within Class B or C airspace or when operating within 12 nm of the coastline.
Important ADS-B Receiver Considerations
When selecting an ADS-B receiver, the buyer should consider battery life, external power capability, and where the unit can be mounted. The pilot should avoid an installation that blocks the view out the windscreen or side window.
EFB Compatibility
Make sure the unit will interface with the avionics already hardwired into the aircraft in addition to your EFB of choice.
Frequencies
ADS-B receivers that transmit on multiple frequencies are better because they allow for better coverage.
GPS
GPS is a nice-to-have navigational tool in the cockpit. The ability to find the nearest airport or follow the magenta line in IFR conditions is key, GPS units that show terrain are a bonus.
Size
When selecting an ADS-B, consider cockpit placement. If the cockpit is cramped, you don’t want it dominated by the ADS-B. Don’t forget to consider connection cables when you are shopping. You don’t want an ADS-B mounted in the back seat while connected to a cable that barely reaches from the cockpit.
Additional Features
An ADS-B unit that has many features such as non-subscription weather or AHRS can cut down on the pilot workload because the information is at the pilot’s fingertips.
Price
Pilots are so frugal that copper wire was invented when two pilots found the same penny. That being said, for the pilot who just wants enough to be ADS-B legal and only flies on VFR days in the daytime, it makes sense that they would gravitate to the lower end of the price spectrum. For the pilot who spends a lot of time on cross-country flights or in IFR or night conditions, more versatility is a bonus.

FAQ
How does ADS-B traffic work?
ADS-B signal bounces off the satellite to create a 3D representation of where the aircraft is in space. This information is transmitted to aircraft control and other aircraft in the vicinity that has an ADS-B receiver.
Which is better: Sentry or Stratus?
Neither one is better; it comes down to pilot preference. It’s like comparing Coca-Cola and Pepsi.
Can ADS-B be turned off?
ADS-B can be turned off in the cockpit, but to do so in airspace where ADS-B is required is a violation.
