Thread: Quick question about signal and diff sats

If you are using SW21's, which I think you are, then as it is the even transponders that are low, you must have a partial short on a line somewhere.

Check all connectors, replace them if there is corrosion etc.

Have you tried to install a splitter on any of the lines.?

It is doubtful that it is an LNBF issue, or BOTH switch's for that matter.

Yes I belive it is the SW21. From what I recall that is the switch that came packaged with the system.

Where would I install the splitter? I already have a couple on hand so I can try that, just need to know where in the line I should install them and what I am looking for after.

On sat 82 all the transponders (that were active and not 0) were 76 or above.

Okay. So in theory, if you swap the lnb's, you should gain good reception on all transponders on 91, and your evens on 82 should decrease (similar to how your current 91 is).

SJ44;

What do you mean by "Maybe your dish is aligned on the border side." ?

When you say "swap LNBs" do you mean moving the whole Sat 91 LNB into the spot where the Sat 82 LNB is now?

I disconnected the two leads into the 91 and swapped them and mad sure they were tight. No difference.

Yes, physically remove both LNB's and put them in back in reverse.

Swapping the leads like you did won't do much. I think you may have a weak LNB like I suspect I do. My new one is on the way, so I will know for sure hopefully by this weekend.

Ok I swappped the LNBs.

Now my 3100's transponders are all in 85-100%

But my sat 82 (HD) have all the even transponders around 50 or less.

I guess my LNB is bad?

Maybe I should have been clearer, I was wondering if you HAD installed a splitter as this is the problem that is seen when a splitter is installed.

Splitter CANNOT be used on Satellite systems in normal installations.

I am having the exact same problem as you, except ALL of my even transponders on 91 are weak (40-60%).


I was having troubles with my 82 signal, so I went up and repositioned the dish. I sacrificed some 91 (down from 94% to 86% on T11), but my 82's are up in the 80's now. BUT now my 91' evens are low.

I just remembered I did switch the lnb's around before I repositioned the dish, but didn't notice much. I am wondering if my original problem with my HD reception was that my 82 lnb (which is now my 91) wasn't getting a good signal on the evens.

I guess my question is, can an LNB be defective on just the odds, or would the odds/evens both go out.

Ugh, time to go record some levels and switch the lnb's around.

SensFan, didn't mean to hijack, but we may have the same problem.
