I used to have the big black plastic "trash bin" lookin thing on mine. then went to change out the lnb cause it just wasn't cuttin it (back in the analog days, btw) It's only about 80 degrees, but I couldn't even hold the lnb, it was so hot. Never had my lnb's covered since then. Just Scotch 33 on the connections. And that new, now 18+ yr old, lnb is still workin. Only recently replaced it as I went to a true FTA type(voltage select polarity). If you prefer to have a cover, I suggest white, and plenty of ventilation, maybe even a fan if in full sunlight and extreme temps (80 +) a lot.
Another thing that can be a LNB killer is paint. Huh, What you say? Yeah, Paint.
If the surface of the dish is painted with high gloss paint, as the sun passes behind the sat, the suns rays are focused on the LNB, making a nice solar oven. And because the diameter of the sun is N degrees wide, it's there for quite some time. (I've had some wives of customers (BITD of analog subs) do just that, When told they had to paint it over with flat paint, some threatened their hubby that it then had to go. I know of one that did.) I hope your cover is white, and the black ring it mounts to, I'd fill it full of holes for ventilation. Glue some screen over them to keep out the bugs.
OK- Back to your band select hickup. How are you doing this, DISQC or 22khz sw?
could be a problem there. For initial tune up, I ended up removing my band switching, and only used C band. Then when tuned up on C, I Just swapped coax to the KU and did a small polishing up of the alignment. Remember, beamwidth on Ku is a fraction of what it is on C on a BUD. Then I added the switch for automatic band switching.
BTW just figured out my initial confusion earlier.
Zenith - 33.94 = Axis - 29.72 + Declination - 4.22
Extreme slope (NOT ZENITH, but at ZENITH) = 33.94 = Axis - 29.72 + Declination - 4.22
Guess I've never measured it that way and didn't know what it was called.
Just measured the Polar angle, and set to Lat.
Then measured dish offset and made sure it was DEC. Chart degrees different.
Anyway
90 - 33.94(Extreme slope) = 56.06(dish look angle at ZENITH) so we are talkin'
the same angles, just using a different angle because of a a different reference.
shankle, just take your time and keep cool, I've had heat stroke, and it ain't fun.
Aligning a BUD for the first time is a test of patience. But you're well on your way into C band.
