New Lnb changer

[Lazarus]

I scared of upload failure

I think you speak for us all.

This is what I recorded



I then tested the measurements to the laser dot with the pole removed,
total length A to dish via B 1310
Top if dish to dot 1025 , bottom of dish to dot 940 . Measurements along curve of dish face.



This means my lnb does not look directly at the centre of the dish , just about 40 mm below.

I inverted the laser to get the beam at centre lnb height and wedged a piece of rubber under the front of the laser to make it centre of dish 980 from bottom.

Re-checked A - B now 1135

Folks, Laminas 1,8m owners, can any of you could measure exactly working area of the dish A-B and C-D, and also depth from point E to the surface of the dish. Please
Does anybody know what is offset angle of this dish?

A couple of things I have noticed,
Feedsat_DXer´s dot is higher than mine.
Feedsat_DXer´s A - B is pretty close to my total length to dish, did the machine read to dish rather than point B ?
Looking at B - C with the dot corrected to centre of dish 1020 would be about B to top of dish, according to a rough adjustment from the reading I took.

Hope this all helps in some way

A - B 1935 mm, C - D 1800 mm, E already covered , 170 mm.
As for angle, don´t have ow´t to measure that, but from Laminas it is 22,6!
( Measurements taken on the dish I haven´t put up yet )

Edit, the link! LAMINAS. AS-1800 Offset Dish

Yes, I've seen 1935x1800mm in specifications, but thought maybe somebody checked those dimensions. Somehow I do not believe that with 1953x1800 is possible to get 22,6* offset angle, according to calculations offset angle should be 21,5*.

Since the main beam of a changer with the top-side motor is a lot shorter , the sidearms are also .
At the same time the Laminas sidearms must be pointed lower , so they must be bended at dish side .
No point with a CM there the arms are attached to the side of the dish and can turn a bit .
Thats a unsure point for me , do the arms stuck some part inside the dish ?
Can someone show me a picture of that hole and messure how deep it is .
Another uncertain point is the focus line/lenght , it would be helpful when I know the A-B and B-C dimentions .

Just read the last few pages of this thread, and if I´m correct you intend to drop the lnb holder to accommodate the lnb changer?
Due to the construction of the Laminas lower support arm, bending the arms alone won´t work, in my opinion.
The " solid " construction of the lower support arm will not allow a simple bending of the side supports.
I think you would have to drop the bottom support arm, using longer bolts and spacers of some type, and extend the support arms?

Just my thoughts!

1935 x 1800 is correct, just checked it on the plate I have not put up.
On the one that is up, how can I confirm the offset angle? I do not have anything other than a tape measure, good eye, and slightly used brain!
If you are correct, could explain why my " red dot " is 40mm below where it should be!

Was trying to do that in several threads, for example here and here

Have not read through both those threads, yet, but will!
Are you saying that Laminas, and possibly others have F***** up! I actually think you could be right by my own findings, let´s face it, who the hell puts a laser level on a " well known and reputedly well made dish " !

Edit: To any passing God, please leave this here for a while, as this is a well read thread. Should the need arise to move this discussion please make sure it is well posted to where it goes, thanks, B

I can send to paypal as soon as you say you are ready then, thank you

Also importent , whats behind the dish ?
I presume You want the backside reinforcement too , please give me a picture of the dish/mount

Always good after a curry!

No, they are closer to bottom than they are to the top. The distance between the two attachment points is around 157cm.

CJ , You missed the first question about the FOUR holes where the mount is bolted to the dish .
And the last question (for the day) the distance from the real bottum edge (not from the round feedarm) to line between the sidearm holes .

Since we appear to be talking in code, I will no longer be a part of this thread!

Ah OK. I know D = 35cm and E = 30cm. I will take A-B and A-C measurements tomorrow.

A few postings before , WHATAGOAL1 wanted also a changer , I asked him for what brand dish ?
CJ answered it for him and a later WHATAGOAL1 wrote :

Later I realized I also have to know does He use a polarmount or H2H rotor .

Not your fault at all Trust1 , totally mine. I had a bad day and was having a bit of a meltdown moment. No excuse, should not have made the post.
I apologise to all on this thread, all members and guests viewing it and all 72 robots on line at the time.
As a regular member of the forum I should know better, sorry.

The lnb changer comes with a new main lower support , the original support can't be used .
