What signal strength & quality do you get when connecting it up in the
loft
? i.e how well aligned is your dish ?

If the alignment's not great, then that, coupled with the long-ish
length
and multiple joins could be causing your problems.

Cheers,

Tim H.
Running out of suggestions too :-(

No kinks... and no shorts.... nothing else running on the cable...
