Can you guys list a full set of recommended component models required to setup a motorized 1.8 m C-band BUD in a congested city conditions (including everything)?

Is it generally a good idea to transform it later to a C/Ku-band motorized reception set, and how it would change best components set selection and specs?

Are you guys saying that Ku-band LNB inside these dual C/Ku-band LNBFs can't be moved independently within the LNBF Ass. along its axis back & forward to find the best focal position for Ku-LNB only? Is there ever a need to move it, or another approach can be used to achieve the same result?

Are you guys saying that Ku-band LNB inside these dual C/Ku-band LNBFs can't be moved independently within the LNBF Ass. along its axis back & forward to find the best focal position for Ku-LNB only? Is there ever a need to move it, or another approach can be used to achieve the same result?

Remember the mouth of the feed is roughly at the focal point of the dish, not the LNB. The feed acts as a waveguide, to some degree, which transfers the focused signal back to the LNB, whose probe is really the antenna. The length of the waveguide has nothing to do with adjusting the focal point, but it is important for other factors. Combo feeds have coaxial waveguides, the outer tube is for C and the inner for Ku, because waveguide diameter is critical to guiding a given frequency range with minimum loss. Thus the LNBs for both bands each have a waveguide from the focal point. There is no separate adjustment for C vs. Ku focus because positioning the feed's mouth is all you need to do.

The first diagram you posted is a little misleading because the focal point of a parabolic dish is in the same place for any signal frequency. You can even focus light if your dish is aluminized and fry your feed. The focal 'clouds' may be different because of imperfections in the dish, but the feed cannot take this into account. The optimal location of the feedhorn mouths for these clouds may be different for C and Ku, but that should be incorporated in the feed design. I'm not sure what the second and third pictures have to do with this; it looks like the second has a properly set f/D on the feed and the third is under-illuminating because the f/D is set higher on the feed than the dish's f/D.

What factors? If Ku-LNB position can't be adjusted independently of C-LNB, then a corresponding cloud catching couldn't seems to be one of these factors?

What factors?

There are more than I want to bother with, but here are a few that come into play when designing a feed waveguide:

1. Long enough to allow a given f/D adjustment range.
2. Short enough to minimize losses.
3. Capable of mounting LNBs so they don't interfere with each other, the scalar or the mounting arms.
4. Room for a dielectric or 1/4 wave plate for circular feeds.
5. Access to set-screws to adjust skew.

None of these have anything to do with focal point optimization, but are probably as or more important to a successful product.

If Ku-LNB position can't be adjusted independently of C-LNB, then a corresponding cloud catching couldn't seems to be one of these factors?

Designing a feed is not like designing a bookshelf. There is science, art and magic involved, and a feed designer is faced with constraints, optimizations, compromises and complex interactions, many of which s/he cannot control. An example might be the topologies of focal clouds, which will vary with the frequency, dish model, manufacturing tolerances and surface condition. We want one-size-fits-all, but that often means less than optimal performance. Some feeds may work better on certain dishes, but you won't know until you try. Fortunately the differences are usually not important.

Modern feed design is best done by computer simulation rather than cut-and-try. This allows the balancing of conflicting factors, some of which are hard to measure. A few gross adjustments are possible with feeds, but building a feed with separately adjustable mouths for C and Ku sounds like a theoretical and mechanical nightmare to me. Adjusting one relative to the other is going to have complex positive and negative effects on both, many of which cannot be measured by typical FTA users. The more adjustments you provide to a lay person, the more likely they will screw it up to the point that nothing works.

My advice is to be happy and not to worry. A good feed will take the necessary factors into account and do a good job optimizing very complex demands. Your job is to adjust your dish to track the arc accurately, ensure the feed horn is in the right place, set the f/D and polarization skew correctly, choose LNBs that meet your performance requirements and have a switching/distribution system that causes minimal distortions and CNR losses to the signals. A lot of people here work hard to get all of these right, but there is so much room for errors that I would not be surprised if many FTA systems are not delivering their full potential. Any single factor I just described will have far more to do with enjoying good reception than feed design details.

I thought I would come here and find lots of complaints about the update to the dish anywhere mobile app, but am not seeing any. It used to look just like the desktop webpage. Now you can no longer filter by sports channels or movie channels. Plus that they made it look like a big button telephone and you see fewer channels in the screen which requires more scrolling. Yes I realize you can look at sports then select which sport you want to look at, I just liked being able to see all sporting events in the guide with all other channels being filtered out. Am I alone in the wilderness on this?

I don't think Tim and Tony are that far apart in Age ...

Remember what Tony said to Tim when they first got back together ...
Tony said: I am the New Tony, Tim .... (something to that effect)

Tony has changed, he's been running his Security Business ... I'm sure he has grown up.

Give it time ... your judging the New Tony from the old Tony.

It sounds like Tim won't be around the Team much longer either.

If you're going try to read / listen to the book (can't recommend the audio book enough) before this comes out, I'd avoid trailers.

Trailer below, spoiling it to make sure you read the above bold message first. The book / audio book are fantastic. Go into this blind if you can IMO!




Kind of disappointed at how much they show. A lot still to see, but man, some good reveals in the book that are just served up here.

A big win for the Patriots, and they are now 3-2.

Browns lose a close one with... The Jets. That is a classic Browns loss (granted, any loss is a classic one it seems). 49'ers, Vikings, and Chiefs remain undefeated. The AFC north have a three way tie at 3-2 for second place. :eek:

I had quit watching this show years ago because I ended up more annoyed than entertained. Well......I'm STILL more annoyed than entertained. I DO find it interesting to see how things work behind the scenes at many businesses. What annoys me is how utterly out of touch CEOs are with the companies they run. At the end of almost every episode the head of the company is amazed at how hard the employees have to work and many times have to work around impossible guidelines set forth from headquarters.

I found this one interesting because the new CEO had big plans for this company, Muscle Maker Grill, and it looked like the stores were all pretty busy. Recent history hasn't been good to this company however. I bet the covid lockdowns were the real killer.

Sometimes a thread gets so many posts in it that is can cause issues for the server so that why today we introduce The Song Name Game Part 3!

So let the game continue!

The last song was added by Bobby who posted...

One Meat Ball - Andrews Sisters

CONTINUE ON AND HAVE FUN! WELCOME HOME TO SATELLITEGUYS.US!

Here are the original rules for the game as posted by WebbyDude back in 2006. http://www.satelliteguys.us/threads/68645-Song-Name-Game

Just name a song title and the band who performed it. The next person does the same thing, but needs to list a song title or band name which includes a word from the previous entry. Pick songs from any genre.

Example:

Long Live Rock and Roll -- Rainbow

Rainbow in the Dark -- Dio

Another example:

Ride the Lightning -- Metallica

Lightning Strikes -- Ozzy Osbourne


Get it?


An additional note: we all know that song titles, sometimes, use profane words. Because this is a family friendly website it is advised that you clean up that title up a bit. This is accomplished by using something like sh!t instead of the real word. Thanks....

For quite a while now, people with a VIP211k have been losing their recordings on their activated external HDDs... even when there's nothing physically wrong with HDD. I believe this is an intentional and underhanded tactic that Dish is pulling in an attempt to force users away from the VIP211k.

They are obviously regretting that they ever let users have a "non-dvr" dvr in the first place. You would think they would be happy charging you a $40 one time fee... and then be happy letting the customer be the one responsible for HDD failures.

Dish clearly hates the 211k bitter-clingers. This recording deletion problem is intentional (IMO), and I think it is just one more tool that they are using. Hopper and a 2-year agreement... that's what they want you to have. Think about that... a 2-year agreement... with a company $30 Billion in debt (that's with a B). What happens when all that debt causes them to drop the channel that may have been your whole reason for having Dish in the first place? Guess who's stuck with a service that no longer suits their needs... for the remainder of the 2-year agreement.

On top of that, they don't want you to install it yourself. I purchased and installed all my equipment myself. That used to be common. Now, they lie to me and tell me that my dish must be updated to use a Hopper. Funny thing is... they don't even know what dish I have because they didn't install it, and I didn't tell them. If you ask what type of dish/LNBs the hopper needs... good luck getting an answer. All they know is that whatever you have needs to be upgraded by an installer.

It is quite apparent to me that they care much more about staying in their box, than they do working with the customer. That's too bad, because it hasn't always been that way. It's like they are totally unaware of the current business environment that they are trying to compete in.

I have been a customer since 2010. I will be cancelling my service before the next period. Yeah, I know, my $1,200 a year won't make a difference to them. It just seems like they have forgotten who needs who, especially when you consider the competition in today's streaming world. But hey, they will have succeed in forcing me off the 211k.

Well, after nine months of being on pause, I finally figured out that I was wasting $5 a month. So I cancelled. For the first time since 2010, I no longer have a Dish account.

I do have to say that I did appreciate the account pause option. That just gives a person some time to see what the fallout of cancelling will be... without having to go all the way over the cliff first.

Since I never once had an "oh shoot, I need Dish Network for..." moment, the decision was a lot easier.

Funny enough, when I called to cancel (for real, not playing the pricing game), all of a sudden, they were offering me deals that I was told before that I couldn't get without changing out my VIP211k. Now, I could have had those specials with them just sending me a new card for the receiver. LOL!

Of course, my mind was already made up because of having not missed the service while on pause. That, and the fact that I bet the 211k still kills recordings.

All in all, I'm glad that I had Dish for all those years. I just outgrew the need, and they pressed the issue by deleting recordings. I would have eventually went this route without the deleted recordings issue. But, for sure, that did hasten the outcome.

I'll still pop in at this site from time to time. Believe it or not, I still have a C/Ku BUD that I intend on playing with again if life ever slows down.

Unless things have changed at Dish, which is entirely possible, they won't activate the 211, even as a replacement. I gave one to a customer a while back....which when I turned it off I made sure to tell the CSR I wanted it freed up so another customer could use it, I was assured it was.....and when they called to swap out there's they were told it couldn't be done. Now like I said, things MIGHT HAVE CHANGED.
