Quoting LAXintl (Reply 1):
Satcom antenna cover.

Might it be related to the legacy Boeing Connexion system?

Thanks for info - looks like it's not there anymore. BTW, I was surprised to see the thread moved to tech - it was quite a generic question, not discussing any tech details like some frequency or voltage or pressure...

Tech Ops IS the right forum for this question.

The two smaller black ones are the Satcom antennas. The larger "dome" is the Connexion by Boeing satellite used a couple of years ago for onboard bradband internet via wifi.

Some other airlines that offered it:

Lufthansa
Singapore
Asiana
El Al

So you will see various other 744/343/346/772 etc. with the "dome"

Currently not used/active on any of them as Boeing sold the satellite to the Army.
