Phantom 1 how many antenna cables?

[Cheech811]

I've just received a second hand phantom 1 which looks in mint condition apart from there only is one grey antenna cable. Is this correct as I seem to remember there being 2 on another one I`d seen.

The older ones only had 1 I think the 1.1.1 is when they started to put 2 .
