What Is This Lump On The 737?

Hey everyone,

I was just hoping someone would be able to explain the lump on the upper aft fuselage of this Virgin Blue 737-700.

It looks to be some kind of antenna or communications device but it is quite large, and I wouldn't think that a domestic 737 would need something like this?

Please see the image below.

Thanks,

Monteycarlos

Are you serious? That thing is massive... Doesn't that cause a large increase in drag? I knew about the LiveTV thing but I didn't know the equipment was that big.

As I said, hardly seems worth it for 737's running domestic everyday.

Definitely, but it seems that the extra passengers choosing to fly with them because of the live TV thing bring enough cash to cover the extra fuel cost.

Isn't there anywhere else on the plane they could fit it, or does it need to be exposed to recieve the signal? It must incur a fair bit of drag.

It's similar, but somewhat bulkier than similar antennas fitted on B6 and F9 aircraft.

It seems much bulkier... It could be the red paint, and the angle. Its too bad I am not a better photographer because I would have liked to have got a closer shot to show the sheer size of it.

I would certainly hope that it was worth the money because it is not only hideous, but impractical.

For all those Australians, it better get more than just Channel 7, 9 and 10!

Concur it looks bulkier - but remember, we're looking at a closer shot on the 737-700, further that -700 is a shorter and (albeit marginally) narrower fuselage.

Could be angle, could be sunlight, could be a bad photo  duck  Just kidding Monteycarlos . . .  wink 

It could be two entirely different systems, one just happens to be larger than the other . . .

Hahaha I am not kidding myself. Its a hunk of s**t! It was the antenna thing I was after.

What does the system consist of? Is it an antenna array or is it some kind of receiver dish?

Yes it is the LiveTV receiver that is currently fitted to a single 737-700 (VH-VBO). I was lucky enough to be on that aircraft just yesterday flying Canberra to Adelaide!

The 'lump' IS bigger - they installed the same receiver as Jet Blue then discovered that the satellite signal and coverage in Australia was different and required a larger receiver, hence a much bigger lump. I wonder what the drag statistics are!

Interestingly enough, on my flight, they offer the system for about 10-15mins as a free trial before you need to swipe your credit card (A$6 per flight), but the entire time of the free trial it said "looking for home transponder", suggesting it could not pick up a signal... I wonder how often they have that problem! Certainly didn't inspire me to cough up the $$ to have it for the rest of the flight!

Here are some more shots of it...

If the dish is bigger now, and it still can't get a signal what will this mean for the future of LiveTV in Australia?

If that hump on that plane gets any bigger, they could use it as an AWACS a/c......

Quoting Monteycarlos (Reply 10):

It's a receiver dish. There's a video on LiveTV's website that shows them installing the system on a B6 A320.

http://www.livetvifs.com/media/install.wmv

The LiveTV receiver is pretty obvious on any a/c the system is installed on; on the other hand, the antenna that is used to receive XM Satellite radio is not too big. It's very close in size to the home antennas both XM and Sirius have for most of their units.

Korean Air and Lufthansa have two similar humps for the internet I believe.

The bump is a High-Gain LiveTV radome. As Australia is quite a distance from the equator, it is harder to "see" the LiveTV satellites. To get a better "look" angle, the antenna needs to be rotated to a higher angle, hence the higher radome (actually, there are two antennas side-by-side in the dome). Connexion by Boeing ran into the same problem.

The JetBlue and Frontier domes are used closer to the equator and don't need to get the more extreme "look" angles, and hence are smaller.

I helped certify both installations...

very interesting...

shame that connexion by boeing is to be discontinued.

is there a site that lists carriers with LiveTV (domestic US as well as International) and specifically which aircraft?

Yes, Delta is working on getting the system on all a/c doing flights over 1750nm, not just the ex song crafts.

You are probably best qualified to answer my question: I have heard that the entire system for live TV weighs close to 2 tons. Is that correct?

It might also be worth noting that Delta's live television is not supplied by LiveTV and uses the DishNetwork rather than DirecTV as on B6, F9.
