My SAT-playground

[archive10]

And this is wallmount which came with CM120, 76mm pipe. Have no idea when I will use it, if at all.

Exactly what I need for my new installation of motorized CM120.
Too bad Latvia is so far away... 8-(

Not that far. Quick hop across the Malmo bridge and then a bit across Sweden and down by ferry

well, once I've spent 250+ EURs on ferry tickets and diesel, I could also have one made for me locally...

That is actually in Belgium and you can have it for free, just arrange shipment.

I am delighted by your offer, but I may find it difficult to find proper transportation for the device.
(Nevertheless, I shall investigate through my usual shipping people to see what can be done.)
Much appreciated!

I do not know. It is actually Grundig LNB, old and heavy.

That design looks very much like a Grundig LNB I had in the late 90s except I'm sure the feedhorn was slightly smaller and I used it on a basic 60cm dish for Sky in the UK... I can't remember if it was an Enhanced or Universal LNB. I do remember it being very solid though.

I have two old Grundigs. Using this lnb holder, I can't even adjust skew. The feedhorn is much smaller. If I can find the other one I can take it apart but I doubt it would be of any interest.

LNB looks similar, with minor differences.
I think your LNB holder is for 23mm LNB neck. Did you open feedhorn cover? Perhaps it just look smaller but in reality it is big.

Ah yes, pretty sure that's the one I had.

Brought CM1,2 home. Wife was suspicious, but I've said it is same dish I washed long time ago and it got dirty again and need some bath. That was not a big deal to wash "face" of dish, but bask, as you all probably know, has lots of corners and dirty places. So, I remembered we bought small Karcher steamer. By using this tool I easily cleaned all dirt away. Do not understand why i didn't use this "piece of satellite equipment" earlier! And it could also be used for household needs! Great!
To me, this dish looks like new now! And I like it.

I think it's a 40 mm holder. The bottom part of the holder is v-shaped but the lnb is not round where it is to be held. Strange but I believe these where sold together. Another curious thing is that the front circular shaped part on the lnb neck is slightly larger than 40 mm so I can't move the lnb further away from the dish face to adjust focus. I don't know if this is a bug or a feature, I hope your setup is a feature.

I have once removed the cover of the now misplaced lnb but I don't think it had that many scalar rings. I'll let you know if I find it. It stopped working on one of the polarizations so I might have thrown it away.

So< as I've said in other thread, I finally got my last (really last one) dish, which is Visiosat 1,2m . The dirtiest dish I have ever experienced! But, good thing is that dish already has 4 INOX bolts going through it's face! No polar-mount though
BTW, how many lifes cannabis has? 5 or 7? Back of this dish looks like 5-liefer!

 

[Captain Jack]

That reminds me - I have the steam cleaner thing lying around as well!

 

[RimaNTSS]

Even with steamer work was not so easy. But final result is good (I think) .
Already changed nuts&bolts to proper ones. Everything what is above red line goes directly to trash can.
Lots of spiders been living in corners, inside the feedarm and LNB holder. More than 7! They also had lots of eggs ready to hatch! Good I cleaned this dish

 

[RimaNTSS]

Of course I could not resist to put antenna in one piece and check where LNB was pointed. And found out it is aiming at spot about 63mm down from antenna's center directly on vertical axis. So, Visiosat did think about getting maximum performance of their systems.

 

[Trust]

Rimants , maybe you did not see that Visiosat cut a part of the dish ? If you count that part to it , you will see the spot is too high .
I'm believing to that dish manufactarors do that to pickup less nois from Earth , why else they cut away that section ?
Also Triax seems to use the lowest section just to attach the feedarm .

 

[RimaNTSS]

maybe you did not see that Visiosat cut a part of the dish ?

No, I see it well. Center of dish I found pretending the dish is with bottom part. Dish has small axis 1200mm, big axis 1300 and center of dish is exactly where I put green dot. Dish also has markings on sides, those marks indicate where horizontal axis is.

 

[Trust]

But scanning it with the rotating laser following the full edge should show the spot is leaving the dish at that "removed" section , so missing a part of the reflected signal .

 

[RimaNTSS]

Spot will not leave at "removed" section. I marked blue spot which is about 80mm down from where laser hits the dish now, so if there was rotating laser be inserted its beam would not leave the dish.

 

[Trust]

If the rotating spot dont leave the dish , means there is a lot of aerea outside the projected oval .
