Need more info for a 'guesstimation'. Bu usually, 2° is 'tight' on just about any dish. 4° is usually 'do-able'. To get to 2° you may have to 'Siamese' the feedhorns. Seem to remember, quite a while ago, something like this, but don't remember if it was for 2 or 4°.(???)
C or Ku? What dish?

Unless you use a large dish the odds of getting both reliably are pretty slim. The smaller the dish is (30,36,39) the spot where the LNB's have to be are too close for a normal LNB to be put together to work.

Now if you had a 1.2m dish (4 foot) then the odds of making it work are better

If you get a couple of the GeosatPro LNB's that are designed for 4 degree spacing on a 36" dish would probably work on a 1.2m dish...

Here is a old pic of when I had 2 LNB's aimed 3.8 degrees apart (107.3 & 111.1 for Shaw Direct sub) on the 1.2 meter dish. Now the LNB head is pretty big there but if you got a newer LNB that isnt so wide it would probably work

What size dish are you working with?

Same song, 100th verse...

Some years ago, one of the members developed a simple equation to predict LNB spacing.
It took into account such variables as viewers location, orbital position, and focal length, all of which impact the results.
(and maybe other things; it's been a while since I looked at the solution)
It's time we quit guessing, and did it right; it's not hard!

I have a 90 cm. dish fixed to Galaxy 3C @ 95w and I guess by sheer luck I also get Azteca @93w but signal is not strong (sometimes watchable, sometimes not) just like Iceberg said is very difficult to get 2 close reliable signals.
I tried getting both 95 and 97 on a 90 cmts dish but just like mentioned it´s too close to work.
Therefore I also have another dish fixed at 97W ;)

Wescopc took two GEOSATpro bullet LNBFs and used a belt sander to grind down the housing and scalar to receive 2 degree separation satellites. Can be done with modifications!

Yea, but as I recall, that was on a bigger dish.
...if memory serves....
(1.2mtr?).

We need to find the link to his thread.

I have a 30 inch dish and universal lnb connected to galaxy 3c now. I also have a 36 inch dish. Thanks guys. Have anyone of you try to get 2 sateelite with 2 degrees apart before. Whats would you recommend. I have a usb birdog meter.

According to the references, linked to, in posts #13 & #14 it's going to be impossible with your dish.
[the birdog meter won't help the situation]
Whats would you recommend(?).
Read those posts referenced. Then, with a 1.2m dish and some 'machining of a couple of LNBF's, you could try.

Hi, I did a 2-degree experiment once, and it worked for me. BJU dish, pointed at 97w, receiving both 97w and 99w. 99w quality was 45-55, if I remember correctly. I think quality would have been better if I had those small bullet lnbfs.

If you just want CCTV off of 95w then I think it can be done since it is so strong. I would leave the LNB for 97w in its regular spot and tuned in as best as possible. Then I would take a cheap LNB, hold it near the 97w LNB and using the receiver or a basic meter find the best 95w signal. As stated previously parts of the LNB scalar rings would overlap so you are going to need to grind off a section of them on the 95w LNB. As long as you don't grind into the feedhorn itself it should still work pretty good.
