A little less analogue, and a lot more crap.

I've had a delivery of the later style Hybrid LNB from Visiblewave that I thought might be like the others with an elliptical feedhorn, but it is a standard 40mm collar with suitable clamp for the Mk4 Raven dishes.

This was to have been bolted onto a Mk 2 dish at a client's house with the larger feed support, but of course the Mk 4 clamp won't allow that. The Mk 2 clamp won't fit round the LNB collar with the only option being to cut off the skirts and somehow bolt it to the support, which will look messy.

So, is there an adapter that converts 40mm LNBs for the Mk 2 dishes ?
 
Is the clamp for the MK2 too small or too large? If too large some PVC pipe of the correct size can be used to make up the difference.

I had a friend with a small wood lathe turn down the outside and inside of some PVC pipe to make a LNB neck one fit an older dish mount, what I did was find a close outside diameter pipe and and a glue in reducer, he then turnd it down to fit the old clamp that was too big, and then the inner diameter to fit the old LNB neck, this piece was then split on a band saw and clamped in place.

Also some of the LNB mounts I have used in the past came with 40mm and 30mm adapters.
 
LNB for Mk4 dishes are elliptical and smaller than the 40mm collar on this one. No platic available to ream out the clamp.

Annoyingly the single screw clamping system for the LNB is also reversed on the two collars
 
I just used PVC water pipe for a plastic spacer.

I will look in my junk bin and see what I have around, the big problem would be shipping, it would cost more then buying a new one.
 
He needs a smaller one for the LNB, and one that would fit the MK2 dish's feed support....Time for a 3D printer maybe??
 
No, I require a bigger clamp for the LNB, and the sleeve fitment that goes inside the earlier feed arm.
 
Sorry, I thought you had to go smaller, what size is the current LNB"s diameter?
 
This may be a silly question but why not just replace the dish with a mk4 minidish?

That was the second option, now I am left with a second hand dish with very limited usefulness.
 
Use the face hanging under a bird feeder.:) Either that or the bin.:)
 
I noticed minidishes tend to suffer from rust issues after a few years anyway. Keeps installers in business I suppose or is that just conspiratorial on my part?
 
An Alba dish for the original Sky signals.

Just round the corner from me

Not one of mine. One of the early S ky dishes, branded ALBA and I think they only came in white. It's seen better days

Sky have no interest whatsoever in keeping installers in business, from their point of view they would be happy to never visit the property again, unless it's to upgrade the box for bigger profits.:)

I was being a bit cheeky in my comment.
