Dish alignment question

[Mark0]

Had work done on my roof and temporarily removed the dish. Now I'm not pulling in the 77 bird and it appears the other two are not coming in as well as they had before. Something tells me maybe I've got the 61.5 and the 72 bird coming in on the wrong LNB's. Is this possible and maybe I need to rotate the dish 5 or so degrees to get it back into the correct alignment? I have an eastern arc dish.

That's probably what's going on...... Do you have a meter or are you just aligning with the BEEP noise turned up loud?

You can cover the LNB's with foil to find out which ones are "alive" for troubleshooting purposes.

yeah, I roughly aligned it based on where I thought it should point, then tuned it in with my meter. I assume the LNB's are in order, 61.5, 72, 77?

Cover the two outside lnb's and see if you still get 72.

Lower the dish 3 degrees on the elevation and try to aim it again. 72 has an elevation 3 degrees higher than 61.5.
