Think so, I know I tried one connection only.

Thanks John, that's an idea. If that works and I detect the signal on
two cables I can move one thrower wire to the other and work out
which is the duffy one, or simply use the two good ones.

Something to play with whilst it's wet, cold and windy outside.

<later> Nawp doesn't work.  B-(  If I can detect the thrower at all
it's the same on all cables. I suspect that's because the screens are
all connected at the LNB, certainly the signal at the thrower
virtually disappears when you connect it two screens, as if shorted
out.

Cheers
Dave.
