I noticed that Saudi Arabian Airlines 747-468's have two satcom antenna's like the photos below show, all the other widebodies I have seen, have only one. Are there any other airlines that have a dual antenna system like Saudi Arabian, and also, does Saudi Arabian have a unique requirement for the dual system.

Thanks for all the replies.

It all comes down to how much you can afford for what your needs are...
There are a few other applications with multiple antenna installations.

Some 777 have dual (LH and RH) satcom installations.

Hi,
I knew that Saudi Arabian was investing on the Internet on Board technology on its long haul fleet.
This technology requires, in most cases, a specific satellite antenna.

So this could be the reason why you see two antennas...

Ciao!

He means LH (LEFT HAND) and RH (RIGHT HAND) Satcom's. Not the 2 letter code for an airline...

When the 3 Saudi 744s were delivered in 98/99 (already with the double satcom on the back) there was no such thing as onboard internet. I also wondered why they have this feature (I´m pretty sure only one or two of the Middle East rulers private 744s have that double bubbly too). Onboard-internet pioneer Lufthansa have a bigger bubble installed now on some of their 744s).

The dome that HAWK21M shows is a Marconi satcom dome. The Saudi 747s seem to have two of this dome. Its probably to double the number of possible telephone connections.

The Connexion By Boeing dome is much bigger. Here are some examples on Lufthansa A340s and 747s. On the A340 I think the forward dome is a Marconi, while the aft is definitely a CBB dome:

LH got their 744s in basically two batches: D-ABVA upto -VN and D-ABTA up to -TH from 1989-92 and D-ABVO up to VZ and D-ABTK/L in the late 90s up to 2002. The second batch got the Marconi satcom. None of the original batch was upgraded. Thats why you can still tell these aircraft apart.
