Am Losing My Hair Dish Problem

ameen27 · 18-09-2007

I have 1.8 dish I gave up on nilesat because i was unable to pickup the signal so I decided to use it on arabsat instead with cambridge c120 universal lnb the problem is am drying to pickup arabsat 26E and I been doing this for almost a week now but no luck i was able to pickup hotbird, astra 19E also astra 28E but not arabsat am I doing something wrong

here is a picture of the dish

With a 1.8M dish you shouldn't have any problem, except perhaps too much signal from 28.2E.
The 3 satellites you have mentioned are all very powerful and so you can get them with a much smaller dish, 35cm, which means they are easy to find.
Try TV5 11747 V 27500, this has a powerful signal, and there are no vertical channels on 28.2E close enough to cause a problem.
Then move your dish to 28.2E, change the channel to TV 5, and move your dish gently a couple of degrees to the left, as your facing the dish, you might also need to alter the elevation slightly, but if your dish is in good condition a little patient manoeuvring should get it.

Hi
Is it Arabsat 2B at 30.5E or Badr 3/4 26E?

Also remember that there are C band transponders there also, which you won't get unless using a C-band LNB.

hi,

well i use 88cm from the north east on the badr and at this moment am getting about 56 to 57% goes to 60% at night. you should get it easy, even on nilesat where i once had a 1.6 i was getting about 56% on mbc at night time. just stick a conventional lnb on the end and try that any realy with that size dish for the badr from where you are situated

after 4 hours of battle with the dish i managed to pickup afew channels
however most of them are missing and also the 11747 transponder not getting any signal i tryed everything but no luck i think it might be my lnb as the lnb is very old about 8 years old

can someone tell me which is the best lnb to go which my dish

It looks as if you have got a c-band scaler ring attached to your dish.

Any universal C120 lnb should do it. Try invercom or inverto. Lower noise figure the better, some thing like .2db

Try washin it... a sky lnb in front of that would get 26e 11919h 27500 try one just to check your c120.... the skew will be about right too..

try 12739 h 2400 on 26e its usually the strongest and no confusion with 27500/22000 fec's on sky.... should be 70-80% of a sky tp

what strength did you get on sky and what receiver... any cable problems..?

try

the dish is very clean i get a very strong signal for sky and am using humax receiver.

anyway I was thinking of buying these kit below with the lnb I found
on a website.

i have tried out numerous lnbs and the one i find the best of the lot especially for the sensitive badr, well on my 88cm triax that is, is the titanium, the next best for me on my dish is the sharp, but the titanium does it for me with a tec 1500+, keep on trying you will get there in the end.

Here is some pictures I Just took of my lnb am using on the dish can someone look at the pictures and tell me if the problem from the LNB are feedhorn the LNB is a cambridge universal AE33 C120 0.7db

I know very little about this kind of setup but I have to say the geometry of the whole thing leaves me thinking you are only using about 1/3 of the dish face, most of the signal is passing the waveguide. The focal point seems completely wrong based upon my experiences or it may be an optical illusion. Can you take a pic from the side???

I don,t no about that I was also using the dish before on C band and I was able to
pickup arabsat C band channels The problem is arabsat 3a digital I was able to get
a few channels but most of them is missing and I just don,t no what the problem is my lnb and feedhorn seems fine as I was able to get some of the channels

do you no were they sell dish support arm am thinking of moveing the three support arm and put them on the end sides of the dish but the current arms are to small

ameen27 · 26-09-2007

At last I have Fixed the problem its all was from the lnb and the feedhorn
so I replaced them with a new feedhorn kit and a new invacom c120 lnb
and walla!! i managed to get arabsat without any problem also very good
signal thanks to everyone help!!!!!!!!!
