My first toroidal 90 multi dish install with 20 lnbs

[godzillafan]

Well it's going to take a lot more time yet. This is just the first LNB.

I know - thats why I cant wait. Its doing my head in but I guess thats the point in trying to get it right.

Problem is its still belting it down here and looks not to good to go up a ladder at the moment and have to wait until the weather settles.

Also just managed to get my head around the xtrend 5000 and managed to scan the correct sat 28.2 and got 1045 channles from 28.2 and 13 (was preloaded). I think there was a few double but not bad after scan. reason why the wife says leave it on 28.2 (no TV for a month did that).

Problem is I will lose West if I did that and on the metal bar the overhang is only 7-8cms (maybe 3 extra lnbs on the end)

I'd stick to the original plan unless there is a good reason to change it. Your problem with finding the satellites is down to your method. If you could bring a tv and receiver to the dish that would make it a lot easier. Then you could use the positioner setup screen of the ET5000 to align. This would make thing quite a bit easier because you get almost instant feedback and you know you are getting close even before you get signal lock.

The ET5000 is an e2 box, if you have a laptop use a satfinder program, you can align your dish using that very easily.
It is 100% accurate and works in real time.
I can post one if you want ?

Thats a great idea allright.

Hi guys
Thanks for the great ideas, this how far I got yesterday before the rains came.

Using a s9 and 14" tv below with the family shouting out the readings.

I used the huevos method of moving it 5-6mm to the right.

After some very small moves to the right and checking the pencil line, I found 19.2 and tuned it in to the box and I then managed to tune in 28 as well, but that was weak. The snr on the sat box are very weak 0-40% and some no signal, so the 28 needs fine tuning as the rains came before I could make any changes.

Any tips on fine tuning?

The pc and 5000 sounds great but tv is scart only and i am learning how to use the box.
I am using s9 to check and then scanning into 5000 afterwards.
It's slow work.
What's the computer program called?

This is the prog I use, you also need vlc installed to get a picture.

cheers old boy

i give it a try, hope it works on a t90

cheers for that - its all working and all but how do use it - no buttons or anything to press or guides

the positioner on the xtrend has not changed - loos like i need to set that up somehow

update on the 28.2

I moved the lnb on the bar a few more mms and now picked up the missing channels on the satbox.

Likes of foodnetwork which had no snr 0

now i have got it to 45+ snr and the snr have increased on loads of other channels from 40/50 to 60-75+ figures.

I am going back up to move the lnb back to yesterday's position and going to move the dish a few mms. This might sort it.

I will do it this way (manual) until I get my head around the software and if the xtrend can actually search sats.

At the moment the positioner does not work or needs setting up. The auto scan has no section that shows me the lnbs/sat signal strenghts.

I just go through service and then pick a sat eg. 28.2 yesterday and pressed scan.

But that was after finding 28.2 via the s9 box and then hooking the wire to the xtrend to scan channels.

Anyone else found the instructions booklet useless.

I found 19.2 and tuned it in to the box and I then managed to tune in 28 as well, but that was weak.

You need to go back and read Rima's instructions again. Ok, so you're aligned on 19ºE central and 28ºE is the best it can be moving the LNB along the bar. Now al you have to do is skew the dish. Skew the dish until you get the best signal from 28ºE and then go back to the LNB at 19ºE and make sure signal is the same on 19ºE as it was before skewing the dish.

 

[godzillafan]

Thanks H

Last week I got both well over the weekend. I moved the lnb for 28.2 until i got the best signal and its stable it varies from 44-80% for a range of channels.

19e is a good range up to 80% again.

But this is where I need to get my head around the skewing.

what does it actually do and how do I add the others lnbs- wont they be affected with the movement.

Does it mean once the screw is done then you can add more lnbs because at the moment - nothing else is available signal wise?

worried I will lose the signal if I move the dish.

the skewing is by mms again?

 

[RimaNTSS]

Does it mean once the screw is done

I suspect you are speaking about skew not screw.
I am attaching couple of pictures where you can see how 2* skew changing reception of T90. That means that on the more or less middle LNBs reception is still available, but on the edges is zero.

Dw i heb dy weld ti ers talwn!

Changing the skew makes the focal line of the dish and the satellite arc parallel.

Ok! It's pretty simple. You want the best signal you can get on 19.2ºE. Once you are happy you have got 19.2ºE nailed you can skew the dish. There is a scale on the back of the dish. Tilt the west end of the dish down (the end nearest the wall) until the skew reads about 14.5 on the scale. Then slide the 28ºE LNB along the bar either way a bit until you get the strongest signal on 28ºE. Only move the LNB, don't move the dish. Now you should get good signal on 28ºE. Now skew the LNBs themselves within their holders (and move them in and out too) for the strongest signal. The reason you weren't getting any other satellites is because they are not as strong as the other two, but once you have done the above the other satellites should just appear.

You will have to fine adjust everything to get it perfect on the weaker satellites, but if you followed the above you should now be receiving at least 42ºE, 28ºE, 23.5ºE, 19ºE, 9ºE, 1ºW and 5ºW.

Hi guys

some more pics before I make the next changes

the bar and roughly where the lnbs are at the moment

the back of the dish - the number is approx 90

if I move the scew - well untighten all the bolts and move the dish down on my left side. I will be going 90 down to 14.5 roughly, tighten the screw and see what i get on 19 and 28 and then play with them until I get the best signal.

Once I have them sorted then i can add the other lnbs

is that the plan?

 

[godzillafan]

been trying to load the pic with the 90 on the back of this dish, but the attached file loader is the slowest thing I have used. I will load that picture later

 

[RimaNTSS]

19,2*E and 28,2*E are too close to have those satellites as a reference for skew adjustment. And that is not so easy to skew antenna very precisely (mass production is not always best technical solution). In your case, when you get your central satellite second LNB should be as far as possible, for example 0,8*W, than minimal change of skew will give you maximum changes of signal.

 

[Huevos]

Go 14.5 from 90. So that will take you to around 105. Rima is right about the satellites being close but if you follow what I said above it will get you in the ball park.

Cheers H
heading to 105 today
will report later

 

[godzillafan]

Ok guys

I am about to see if i can get the 0.8W online before i move the scekew to 105

I will leave the 28 and 19 on the dish and add a third lnb around the 0.8w mark - and see if i can get a singal.

If I can get 0.8W then will move to 105.

if I cant, I will report back here

cheers

update

Up the ladder for an hour and no luck

could not get 0.8w on current settings but worse luck

we moved the dish to 105 approx and we lost bot 19 and 28 signals - is this what is supposed to happen

not getting anythind after moving to 105

I am goint to move back to as close to 90 as I can get and report how much the ckew let me tune in

update later

 

[godzillafan]

Update on the screw

Right when I took it to 105 - the lnbs died and no signal was gained anywhere.

I worked backwards and got the first singal from about 93-97 approx on the back panel - I would say around 95

is this any good

I am now going to try and see what I get on a 3rd lnb
