Gibertini lnb holder

[Archive-8]

Do gibertini make a 60mm lnb holder for a c-band lnb?

As I am using the gibertini rail at the moment with no problems, but I can't seem to find any clamps.

They are all for a 40mm feed

Thanks if I can find on to put ku lnb in the centre and twin c-band one on each side. It's got me thinking.

Thanks again.

I doubt you will find anything like that, and if you do it will be Heath-Robinson. Better off making something yourself.

I am using two Stab Motor brackets (probably other motor Brackets will do - SG-2100s) plus two studs. Do the job perfectly

Chris, don't you already have two C band LNBs side-by-side?

Yes I do. But not 100% happy with it as one of the lnb's move slightly.

Plus I had seen some on a straight bar instead of the curved one, and wondered if I could squeeze any more Db out of them.

I am using this with two of these on my 1.5m Gibby.

I have just ordered both. That looks much better :-)

How is the 63mm clamp bolted to the rail? Have you got a close-up photo?

 

[Captain Jack]

Just drilled a hole in the rail and bolted the clamp to it.

You can see a bit of it here... http://www.satellites.co.uk/forums/threads/couldnt-resist-a-new-dish.160671/page-3#post-879479

Did you experiment with the depth? My C-band lnb's needed to be further from the dish than that for max signal.

 

[Captain Jack]

Made very little difference, if any, to be honest

because my lnb's were further from the dish it was possible to get closer together without blocking the ku lnb. Offset about 2.5 degrees. I'll post a picture later.

What did you set the scaler rings to? Mine are set to just of the 40 mark.

What settings are the scaler rings? And what size dish is it?

 

[Captain Jack]

Took some cobwebbed pictures today... the scalar ring is on 43 mark - haven't really played with this to know the difference.

Mine are set to 28 to continue the same cone. The LNB should be pushed through enough to form a 4th concentric ring the same height as the other three. If you take the cover off a Ku LNB you'll see what I mean. But mine are a slightly different design with a deeper back so yours will be set to a different depth. The important thing is the LNB is pushed through to the same depth as the previous scalar ring, so you have four matching rings.

Thank you for that I will go and have a play with them. ;-)
