Antenne Sous Capot Speciale Train

I doubt the aerial would be built under the 'hood' [US] or 'bonnet' [GB] of the crane (even supposing it had one!) Usually, any such aerial would be placed as high up as possible, and would be protected only by a (say) plastic 'dome'-type cover, as the probably metal 'hood/bonnet' would tend to block the signal.
My own feeling is that this is simply an aerial within a special non-radio blocking cover or casing — a housing, probably made of some non-metallic material, and probably mounted on the roof of the crane, train, or whatever. Clearly, it needs some kind of prtection from the elements, and also, probably from mechanical damage during lifting / handling operations

It's not beyond the bounds of possibility that this is an aerial originally designed for use on trains (of which there are many!) but here being used on something with perhaps a similar roof construction, a crane (of which there are of course many fewer!) — I doubt there'd be much demand for a special 'crane roof aerial'.

The hood is on the train. Unless a train is part of a crane, but I don't think so.

My guess is that it is a radio Antenna built inside the hood of the railway crane. What do you think?

OK, so if you want us to 'verify' something, please can you tell us what your own proposed translation is, so that we can 'verify' it?
