Visiosat Ku Rotating Feed

[s-band]

I acquired this thing which was from a VSAT terminal. I don't know what dish went with it but it had a Channel master OMT etc attached. Has anyone any idea about the f/d that it's may match? (My guess is 0.6 most likely or possibly 0.8, the latter for Prodelin) I can't find any info on the web and there is minimal data on Visiosat professional gear. The part number, 4084918, returns nothing on Google.

I can't work out how the PTFE window became damaged. Heat doesn't touch it. Maybe someone prodded at it.

Oooh, now that is nice...
I have not seen a Visiosat with an f/D on something else than 0.6.
But since these are VSAT terminals, it may just be 0.8 (to give the good H/V separation).
Doesn't look like a 0.6, but then again, looks are deceiving...
Why not email Cahors directly (in French, of course, to speed up reply-time)?

... birds such as starlings might have had a go at it Graham, iv'e seen them on my 1.25Gibby through the dish cam having a go at the lnb caps until iv'e nudged the dish to scare them off.

I wondered, there is more of a cone than 0.6 feeds. I registered on their pro site but it seems to take 5 days to get approved.

I think it is about 10 years old but doesn't look like it has been exposed to the elements. The PTFE is quite thick and the dimples are quite large. Hence not thinking that it was bird damage. I know it was on a roof but that's all so I presume it was in a radome. As the PTFE is thick, I think I'll replace it as it will distort the beam. Perhaps it was domed originally.

Another problem is attaching it to a C120-WR75 transition. I can either get something like this WR75 to C120 Adaptor L=40 - Roks if I can find one or counter-bore the C120 ring and fit the LNB before re-assembling the whole. More pics:
