Nope, this stuff is stranded. As Geoff points out CPC have got it:
http://cpc.farnell.com/jsp/Aerials+&...g+Accessories/
MAXVIEW/D4307/displayProduct.jsp?sku=AP00050 or
http://preview.tinyurl.com/yoyy8p

but it's only 5m so the o/p may still need a join. I don't know the
right way to join these but wire rope grips should do the job. The
smaller sizes of galvanized grips are mis-described on the CPC site as
wire rope.

==================================
Are you sure that *stranded* wire will hold just by being bent and
twisted back on itself? Usually it needs some kind of clamp or even an
'eye splice'. Is this the same (under a different name) as 'lashing
wire'?

My, you've got your sceptical pants on this morning ;-)

I had my doubts too but after seeing it close up on a roof and hearing
it spoken about on the digital-tv group I do believe it is self gripping
when looped back and twisted correctly. Take a look at the pic in the
CPC link and you'll see it has a very specific tight twist which I
believe is the key. It does sort of make sense as it removes the need
for too many tools and fiddly operations on the rooftop.

And no it's not catenary wire.

==================================

Thanks for the explanation, I'll take your word for the special twist. I'm
not sure what I'm supposed to be looking for, but at least I now know what
'lashing wire' is used for. Most of the stranded wire ropes I've seen
have a life of their own with every loose strand very stiff,
needle-sharp and determined to go its own way - mostly into my fingers.
