Besides being a bit of a radio geek, I also love aviation and am working on my PPL (private pilot license). I recently discovered this image [above] of the Boeing 787 antenna compliment. It’s amazing to see how many antennas they fit on this heavy bird!
Thank you for sharing, Sally! I can assure you, you’re not the only aviation nut here on the SWLing Post. I’m guilty as well!
It is amazing to see just how many various antennas are install on modern commercial aircraft. Looking at this image, you would think it’s a flying antenna farm!
I’m quite surprised to see an actual ADF antenna and a marker beacon antenna. Perhaps these are used in other parts of the world. They can be legally substituted with a GPS fix according to the FAA.
The EASA (AFAIK still) frowns upon throwing ADF equipment out of commercial airliners, and even in the US you still need an ADF for commercial flights into airports with a full GPS approach coverage, when your alternate requires one (IOW no GPS overlay published). I’ve heard it can be as ridiculous as the approaches all having GPS overlays for LOM and ADF, but the MAP is containing an ADF fix. 🙂
I don’t see the ADS-B antenna. Maybe it’s here under a different name.
There is no such thing as an “ADS-B antenna” (on planes that is). ADS-B is a function of the transponder, and the transponder antenna is listed as “ATC” on the picture.
