There is a square panel about halfway between the DL logo and the American flag, on the upper side of the fuselage, just behind the window exits. Is this some sort of antenna?

Sat antenna. Mounted on the side to provide a fair view of the sky in turns.

Is there a matching one on the other side? Seems an interesting sat antenna implementation compared to the steerable ones in the blister fairings on top.

You mean there is something even Tom doesn't know? Just kidding. But it does seem weird that it would be mounted on the side and not the top.

It would only provide a view during left turns. Right turns it would be pointed toward the ground.

It would be kind of strange. The little turntable type S-band antennas work at 30 degree banks, and a single one of those on top has much better coverage and gain than two flat panels. Unless they're phased array panels, which seems unlikely on a civilian plane.

Hmm... well I guess that would explain the second antenna on the left side....

Yep, it's got the sat antenna on that side too!

Just to add its pretty common nowadays to have the pair of flat panel sat antennae.

My question is, why do some airlines have big humps instead?
Is this for more bandwidth?, for live TV?
Or is it just old stuff? Must cost a lot in fuel consumption to carry a big hump around.

I heard mentioned in some ancient thread (so the following is either true or complete bullcrap) that the bump wasn't that draggy. It did some lifting too or something.

From what I remember, the humps usually involves a rotating "dish" antenna. The flats are phase array.

which seems unlikely on a civilian plane.



(edited for better example)
I think phase array for Satcom is in civilian use. BoeingConnexion (now defunct) antena were to be phased array.

I always thought that was the HF antenna. 767ERs at Delta don't have satellite TV, and only a few of their ERs have SatCom.

I thought the entire DL 763ER fleet was getting the Satcom mod, is that not correct?

Correct, I believe it is becoming the norm for TATL comm. I think it may be required for the most desirable tracks due to reduced seperation rules.

The HF antenna is half way up the leading edge of the fin. You can just make it out on the above pictures.
