: How to properly align your satellite dish - Discussion and Tips
2009-07-29, 10:48 AM
If you can't get a signal, you could have a dead LNB or you do not have line of sight for the 82 satellite.
It's probably a line of sight issue if you get a strong 91 signal and there are trees/houses/walls to the left of the dish or below it (i.e. 82 is to the left of and lower in the sky than 91).
Also, remember that most transponders on 82 are now 8PSK ... only the HD receivers (not 6000) can pick up those signals.
Interesting - I would have thought you'd still be able to detect signal from 82 after the changeover to 8spk, but unless you had the 61**/92** receivers, you couldn't "decode" (for want of a better word) the signal.

I am installing a 20" dish with 4100 receiver. Installed the LNBF in the 91 spot off the Y holder, running straight from LNBF to receiver with no switch. pointed the dish according to manual, sat 91 is no where to be found, but somehow it found sat 82 with 99% signal strength with the LNBF in 91 spot, and no LNBF in 82 spot. What the hell...
From this form, some say 91 is just a little bit right of 82 from behind the dish and up 2 degree on elevation. tried moving to the right mil by mil, no luck, still can't find 91. Not even a weak 91 on transponder 11.
disconnect all, did a switch check, and try again, still nothing. What is going on??
Please help!! BTW, my location is Calgary, AB. Thanks.

91 is there, you just need to try again. You sound to be doing everything right, so it is just a matter of trying again, try going up another degree or two.
Unless there are any Line Of Sight issues, Trees, etc, blocking 91.

Last weekend I had my roof shingled and had to take my dishes down. I set them back up and didn't have any real difficulty with aiming them properly again, but I noticed an oddity that may have been there before. On my dish with dual lnbs I am getting a weak even transponder issue with 91. The signal strength is about 10 - 12 % lower than odd transponders. I have checked all connections and cables and even swapped lnbs, but it is still lower. Anyone have thoughts on what to check next?

if i got signal from 82, doesn't that mean there is nothing blocking the signal?
so i just have to keep trying...

If you get signal on 82 it means you can see 82... It tells us nothing about the line of sight to 91 at all.

I had to relocate my BEV Dish today, and I am hitting 82 with no effort at all and cannot for the life of me find 91 either. I have read through these postings pretty thoroughly so I do not need anyone to reiterate the basic installation procedure or anything. I live in Thunder Bay Ontario. According to a satellite finder website, from where I live 82 should be at about 170degrees and 91 at about 182 degrees. The differene in elevation is only about 0.5 degrees. BSed on what everyone here is saying, it seems hard to beleive that they are 12 degrees apart. In my case, I fear a neighbours tree. Once i have found 82 and looking thru the arm of the dual lnb's, I appear to be looking just a hair to the left of the very top of the tree, does that sound like a tree problem to all of your installer types????? BAsed on the info I have the tree should not be the problem. ANY suggestions would be very much appreciated.
Thanks in advance

The birds are at 91 & 82 degrees, so there is a seperation of 9 degrees, not 12.

Looking from behind the dish, 91 is to the right of 82, so if you're getting 82, but there's a tree to the right of where you appear to be aiming (i.e. you're aiming to the left of the tree), the tree might be preventing you from getting a good signal on 91.
There seem to be a lot of recent threads about people getting a strong 82, but having trouble getting 91. This is probably because Bell switched over to a new more powerful 82 satellite last fall, resulting in most properly aimed signals getting 100% on 82. Notwithstanding how easy it now is to get a strong 82 signal, I think the better approach to aiming a dish is still the tradtional, i.e. plumb mast, set skew, look for 91 first by attaching LNB in 91 slot directly to receiver (i.e. no switches), find and peak signal for 91, then insert LNB in 82 slot, connect to receiver via switch and you should have signal from both sats.

Point your iPhone anywhere towards the sky and see all the satellites lined up, on the live video screen.
The app uses the GPS, accelerometer, and the compass of the new iPhone 3GS.
Won't work on the iPhone 3G or Ipod Touch. More info and a demo video at:

Can't find the 91 satellite? "There's an app for that."

The birds are at 91 & 82 degrees, so there is a seperation of 9 degrees, not 12.
9 degrees from the center of the earth as viewed through the equator, and at some places on the surface of the earth, but at most places it is not 9 degrees. Briggles is describing the azimuth from his location, which is likely not the center of the earth. ;)
Briggles, also some online calculators do not correct for magnetic declination (http://geomag.nrcan.gc.ca/apps/mdcal-eng.php).

Using actual direction and azimuth values for your location are only a starting reference point anyway as a milimeter of rotation/elevation represents a couple of degrees anyway and it is ridiculous to think that anyone (without special equipment) can point a dish with that kind of accuracy anyway. Similarly, the equipment itself is not designed to be 100% accurate, bolts for example if loose will allow a minimal amount of slack which translated into a few degrees variation. Since signal reception (at least 'some' amount of signal) is possible over a wide angle, it is generally possible so again the published values are a starting reference only and the dish must be "tweaked" for maximum reception. It is worth mentioning again also that reception of 91 and 82 on the same dish is usually a compromise of signal strength between the 2 birds as the Bell dish is not a dual combined oval and points between them.
Please discontinue the argument about 9 vs 12 degrees and other similarly unimportant petty discussions.

Ok, I'm sure this has been asked before but I am going insane here trying to get Sat 91. I can pick up 82 at 100% easily but cannot for the life of me find 91.
If I am picking up 82 on the 91 LNB which way do I have to move the dish if I am standing behind it and how much movement are we talking? My assumption would be a little down and to the left. Am I correct?

So I've been going the opposite way? That could explain alot!.

i need some help. I found satellite 91 easy and there is slight tree blockage but signal is still high 80s. Now satellite 82 i cannot get at all, although when i go to transponder 1 or 2 it says i have the wrong satellite(Nimiq 91) and the signal strengh is mid 70s and is in red. I dont know what transponder i should be using or what is going on, i eliminated the lnb being the problem by switching them and i am sure there is no wiring problems or switch problems so any help would be appreciated

Has the receiver downloaded to software required.?
What model of receiver are you using.?
2009-09-12, 07:40 PM
yes i just checked for updates and the model is 6131 it is an HD reciever not a pvr
2009-09-12, 08:57 PM
Which model receiver are you using? I helped a friend with an install today and completely forgot that with the transponder changes, an SD receiver can't "see" most of the transponders on 82 (although tp# 15 worked for both 91 and 82).
