Dish 78cm 4LNB

[eliosfederico]

Proberly. I tried several times to to tell Eliosfederico that if the hight of the LNB change he had to readjust the Dish Elevation to.

It is not a problem that the LNB sit higher when on the Rail, but you have to adjust the Dish Elevation. On mine I have a Triax Multiblock on a non Triax dish. I just mounted the Triax square
plastic on top of the NON Triax boom ( arm ) and used a longer screw. But I had to adjust my Elevation acordingly.

Even adjusting the dish elevation don't let me get more signal

I think that I can't do that test because the dish, being bigger, can't be turned that far to 13 because the side of it then touches the barn wall.

Hi Eliosfederico.

You don't have to put the dish in its final position to make the test.

Here a some picture from when I was playing with my 5 LNB 75 cm dish.

I had mounteed it temporary on the windows grill to adjust it before I moved it up on the roof:

And here is a picture of how I mounted the Triax Multimount on the NON Triax boom ( arm )

It worked so well that I never changed it.

Can you get any difference ? Wouldn't you also need to move the dish slightly as the holder is not central.
Maybe a picture of the holder side by side

Cheers Carsten that's helps me :thum: I really don't want to touch anything so if I change my mind I don't have to go back up the ladder, but now iv seen your pictures it might be better for me to mod my holder to fit under the boom and that should be close to normal height but have to check and centre the lnb holder to. :clapping:

I have much the same setup to do but don't want to remove my motor

Hi Ja5on.

I have always 2 dishes. On we use and one for me to play with.

Have you considered to keep your motor and then getting an aditional dish for your multi LNB?

It is possiable to have both a motor and a DISEqC Switch on many SAT Receivers at the same time.

If I remember right is it a questen of which to set first on the cable, I am not sure, but I think it first must be the motor, and then the DISEqC Switch.

Hi Carsten

Yep that's what iv got 2 dish setup already with DISEqC Switch, but my problem is the noise of the motor and neighbours. So leaving 60cm at 28.2 and stick the multi lnb on motor with 80cm. Plus very high up the pole and ladder and ill health too. So I thought leave the motor there and mount the multi lnb holder, I did think if I centre a lnb holder on the rail then I could still move the dish. Its just a idea lol But read a few ppl have done it already.


can we compare like you said and write down values for both 2 weak and 2 strong transponders.

Post the transponders Eliosfederico plz

Tried the dish on my garden on a tripod. With a single LNB pointed on hotbird I get more signal than when with the rail. On my favorite channel I get 78 and before was 73. On the other favorite channel I got 90-91 and before was 88. On the other sats I get almost the same as when they are on the rail.

and this is with what? both dish's and all the lnbs you have ??

 

[eliosfederico]

Triax 88 with one LNB that I use normally on the rail.

well only you know what you haven't done but im shocked you cant get atleast the same % with a bigger dish. I guess your tried anything from adjusting the dish to moving the lnb forward of back and little screw might help. Fine tune !!

Did your other lnb's you ordered not turn up?

 

[eliosfederico]

I'm also surprised. They'll arrive today.

 

[eliosfederico]

I am curious about the opinion of Carsten about why with a bigger dish, Hotbird, stays the same!

I think everyone is lol But there is only so much we can help if you don't give more details like picture of rail and single or anything else you can think of that might help.

You said the new lnbs have turned up but you haven't said if they have helped or made things worse.

How are you checking the difference ? I mean adjust dish then check on tv or with a sat meter?

 

[eliosfederico]

The new lnb's improved the signal of 5%.

Hi.

I think the Tripod is a great way to do it.

1. You wrote that on Hotbird 13E you get more signal than when on the Rail.

2. On the other SAT you got the same as when they are on the Rail.


For 1. I am not sure if that is because of the larger dish or because of the Single LNB is adjusted better than when on the Rail.

For 2. That don't make sense. On a larger dish you get the same as when on the Rail on a smaller dish. Then they are not
adjusted correct.

Even with the 5% improvement with the new LNB do I expect that you will end up with the Triax 88 cm?

It will be possiable to adjust the Rail angle / Dish Elevation so that you will have the same signal level for 2 of the LNB's.
Suggest it to be 13E and 23.5E

You can adjust each LNB in 6 ways:

Sideways, Back - Forward in the holder and Up - Down by Rail Angle / Dish Elevation.

When you have found the right position can you twist the LNB in 3 directions:

SKEW, left - right rotation ( is normally fixed by the holder ) and up - down rotation ( is also normally fixed by the holder,
but if you use a heavy LNB the weight may be change the way it sit in the holder )

If you change one thing, you may be need to make some fine adjustment on the others.

If all above parameters place the LNB in a Equal position as when LNB is in a Single holder will you have the same signal out.


If you can't get the same or nearly the same signal out, can you try to make the previus suggested measurement:

To find out If there is any difference with 13E between 78 and 88 you can try:
1. When single LNB?
2. When Rail, but only 13E in the middle?
3. When Rail and 13E half way out?

Suggest you write down values for both 2 weak and 2 strong transponders.

And please remember that the LNBs position on the rail is different for the 78 cm and 88 cm dish.

The results will give us the posibilities to see where the differences is.
Is it when you move it from the single holder and over to the rail?
Or is it when you move it from the middle of the Rail and out to one side?


And when I remember it, Here is a quote from the Triax MultiBlock Paper manual:

' For additional support of the dish arm, a hole is drilled through back structures and arm
in which the enclosed screw is mounted. See fig 5.'

Please have a look in you own manual to se it.

Hi Carsten. I did already all the tests you have wrote. On my favorite channel I can't get more than 78 with a single lnb. Now with the new lnb I get finally 78 on the rail and I think I'll stop like this. The inverto black ultra gave me 77% and with the megasat high gain I got 78% so I'll keep the megasat. On the box of the megasat it's written 0,1 noise and on the inverto 0,2 so I don't really know if what they say about the megasat it's true P.S.: megasat is even cheaper.

lmfao well as your testing why not try it on the single and see how much you should be getting :clapping:

I should move everything again and I'm a little bored! Probably I'll have a bit more but doesn't really matter cause on the rail this is the maximum!
Still can't believe the inverto was beaten by a megasat

well I give you 10 out of 10 for effort lol but I would test if you have the tripod still up and see if you do get any better

Only 1% lol and but shows how good the megasat :thum: worth checking transponders tho

2 dishs 6 lnbs and one rail what you next plan

LOL looks like the signal get improved only on the channels where the signal was already low, so that's good!
