737 lumps and bumps

[expat]

Has anyone any idea what the two antennas are on the left under side of this 737. I work on them and have no idea. This is our newest aircraft and we are still waiting for the AMM amendment for this particular effectively (it's in the post ). For those who do not know, the four on the right are the RAD ALT.

I have no idea, but I almost know now what company you're working for.

Might be the pilots TomTom/Sat Nav Radar thingy and weather radar.

Weather radar is located in the Nose, no good seeing the weather below you but not in front  ;)

Depending if Air Berlin offer the service could it be a transmitter for on board phones? They rarely make long flights over water so I doubt a satellite service will need to be used, and so this could be used for ground based receivers?

All the best,

PS. Pilot's don't have Tomtom satnav  ;D

I will pass that to the powers that be, but in edited form

DOH! There goes my answer!

Could one of those be for TCAS?  I read that TCAS antennae are mounted with one above and one below the aircraft fuselage.

Of course, that is just a highly uneducated guess . . .  :-[

Speaking of uneducated (and hoping to do something about it), where are TCAS antennae normally located (besides top and bottom) and do they normally extend outside the fuselage?

EDIT:

Another uneducated guess would be broadband antennae.  From what little I read, broadband transmitters for aircraft use multiple, external antennae.  Also, since broadband is a newer service technology and these 'bumps' are (according to the OP) new to the exterior of the 737, perhaps this moves my idea from horribly uneducated guess to wild hunch . . . or something like that.  :-[

I still want to know where the TCAS antennae are.

To answer the last bit, yes...
