The GDL 82 Automatic Dependent Surveillance-Broadcast (ADS-B) datalink, is the latest addition to the comprehensive lineup of certified ADS-B solutions available from Garmin. GDL 82 is a small, lightweight Universal Access Transceiver (UAT) datalink with a built-in GPS receiver. For aircraft owners looking for an economical and turnkey solution to satisfy the requirements of ADS-B “Out”, GDL 82 is a straightforward path to meet regulatory requirements.
GDL 82 broadcasts on the 978 MHz frequency, providing a rule-compliant ADS-B “Out” solution for aircraft operating below 18,000’ in the United States. Installation is quick and easy because GDL 82 utilizes a patent-pending design, in which GDL 82 is installed in-line with the aircraft’s existing transponder antenna wiring to transmit the necessary ADS-B “Out” information. The WAAS GPS receiver required for ADS-B compliance is built-in and a GPS antenna is included to offer additional cost-savings for aircraft owners without an existing WAAS GPS on board their aircraft.
82 also contains AutoSquawk interrogation technology, whichGDL interfaces with most Mode C general aviation transponders to synchronize the squawk code and pressure altitude information from the transponder with GDL 82, eliminating the need to install a separate dedicated UAT control panel and altitude encoder. (Please reference the installation manual to determine if the existing Mode C transponder meets compatibility requirements.) This technology not only simplifies installation but also eliminates the burden of the pilot manually keeping the squawk code in sync.
Pilots who already utilize an ADS-B “In” receiver — such as the GDL 52, GDL 39/GDL 39 3D and the Stratus line of portable solutions — can receive additional benefits as the GDL 82 complements many existing products on the market. With ADS-B “Out” participation, pilots using these products have access to a more comprehensive ADS-B “In” traffic picture, resulting in improved situational awareness.
This unit, WHEN installed correctly performs EXCEPTIONALLY well ! During the FAA performance test, I was not able to cause even one error in the tracking data while performing various maneuvers at altitudes between 500 and 3000 ft. I use the GDL82 RS-232 GPS WAAS output for my Garmin GTR225 radios to pull in the frequencies from nearby airports. However, Garmin instructions are usually not written for inexperienced installers ! For example: It does not tell you that at first powering up the unit, that it may take a few minutes before the GPS WAAS signal becomes available (because the GPS portion, if not used (stored) for several months and shipped more than 600NM, needs a little time to find out where it is). Also some knowledge about HOW and WHERE to apply a ground and use shielding is a must. Although when you read the install manual (which you have to download from the internet), you will find some hints to that regard.
Have not had installed yet but excellent service as always. Aircraft spruce allways comes through in a timely manner. Definitely my go to place for all of my aviation needs. A+++++
Works great! Be sure to do the recommended post-installation checks. I found that transmitting on radio 2 killed the ADSB transmission (bad VHF antenna cable) Probably would not have known if I skipped the checks. Youâ€™ll need a switch and LED if youâ€™d like to take advantage of the Anon and Fail features. You may need a new blade-style antenna thatâ€™s tuned for 978 MHz. See the installation instructions for the compete picture. Youâ€™ll also need a windows 7+ laptop for the configuration and testing. If you donâ€™t go with custom harnesses, youâ€™ll need the proper crimping tools for the 15-pin and BNC/TNC connectors.
shipped quick good deal
Install took a few days of on and off work with my a&p. Worked great right from the start. Glad i went with this for my ads-b out.
Very happy and customer service was great with this purchase as well.
on time delivery
Normal, no charge shipping shipping was extremely fast. Ordered item at 4:30 PM Wednesday, Central time. Item on my door step at 3:00 PM the next day, Thursday.
Works as advertised, the pins to crimp are tiny and take tiny wires 22-24 gauge so be aware of that for the tools are $$ to buy. Flight test went very well for the adsb test. Computer formatting with laptop was straight fwd using printer cord except there is no mention to double click when curser is blinking in box to get it to type :/ ( maybe Im comp. illiterate lol ) This unit has an RS-232 output wire meaning you can output the waas gps antenna to other things .... another bonus which the tailbeacon does not have . Another thing is the transmit test was feeding through my garbage Ameriking elt but by unhooking coax at elt no problems for the test portion. All in All happy with this unit and seems to be solid so far.
Just installed the GDL-82 in my Twin Comanche with no install issues, install took 12 hours. Downloaded the Install Tool and the configuration went well. So far so good pulled plane the plane out of the hanger and did a ground check and everything booted up with no faults. I will do the test flight soon I dont see any issues moving forward. George K.
The box comes with the GDL 82, GA 35 WAAS GPS and the installation kit. You will still need coax cables from the GDL 82 to the transponder antenna and the unit to the WAAS GPS antenna. You will also need wire to draw up the wire harness for the unit.
No. The GDL 82 is only an ADS-B out unit. It does not perform ADS-B in functions.
Yes, this kit comes with the Garmin GA 35 WAAS antenna.
Yes, it is. Though you will want to get a transponder test to make sure your unit is operating properly.
The GDL 82 powers on with the aircraft.
Yes. The gdl-82 will interface with the 327 antenna output to make the signal compliant.
You will need a BNC male to BNC male cable. BNC connectors are based on the inner pin, not the housing. The GA 35 WAAS GPS antenna has a TNC female antenna connector on it.
Yes. Per Garmin, this unit will work with any mode C transponder that is in good working condition. A transponder test is recommended to ensure that the unit is operating properly.
Yes, it is.
You will need a GPS 20A with a connector kit and a GA 35 antenna. This unit can give GPS info to the G5 without having to buy a second antenna for the G5.
