Superdish With Single Five (5) LNB Bracket.

[avenger]

Hello good people,

I bought a single five (5) LNB bracket that I would like to use with a Superdish.

The vendor said that this bracket is able to receive the following satellites: 82W, 91W, 101W, 110W, and 119W. I would like to use it for FTA purpose, but as you can see the only FTA satellite on the list is 101W.

I have just installed/rigged it, but have not been able to obtain a quality signal at all. At what satellite should I point the dish to in order to receive that array of satellites.

I seems that the logical one should be the 101W since it is located right in the middle of the bracket, if that is the case, with two satellites to the left and two satellites to the right of 101w, and LNB 101W being the oddball is there a specific dish or LNB skew set for the 101W.

Has anyone at this forum been able to receive this many satellites on a single or modified bracket with any type of dish, specially a Superdish.

Any input, ideas, information is greatly appreciate.

Thank You.

The bracket you describe sounds like what I would call "a hacker special".....not saying you are but that particular bracket is designed to be aimed just at the sats you mention which back in the day was designed to steal DIsh and Bell

Since KU sats are 2 degrees apart going 9 degrees different will put you between 2 sats. There are adjustable brackets out there that you can get a couple extra LNB's on it but like I say they are adjustable

Thanks Iceberg,

The price was right, so it is not a big loss. It seemed like a good idea to play with it. The thing is that I have this Superdish that I have been trying to put to use for the past two or three months. I have previously posted asking about some ideas on how can I put this Superdish to use, so far no one have given me any ideas of how to use this eyesore. The dish was given to me for free, it came with no LNB. I was hoping that this bracket would be of some help for viewing FTA satellite channels.

I have some assortment of metal strips, maybe I be able to rig something of a bracket for FTA use.

I am open to any suggestions or comments.

Thank You.

Do you still have the LNB assembly? if so is it a Superdish 105 or 121?

121 is actually the better of the two. Folks have removed the LNB where the 119 part is (the pencil LNB) on the back and put a KU LNB on there (one of the stacked versions). 2 KU LNB's 2 degrees apart works real well

Here is what I mean in the pic...now I circled the wrong LNB in the pic but you unbolt it there

 

[avenger]

No, I do not have a LNB assembly or anything for the dish. It was one of the Katrina's casualty, that this guy was trowing away, so I gladly accepted.

The five LNB bracket does not fit the Superdish arm, therefore it is rigged. I am wondering if I could determine the right skew for dish, maybe I be able to rightly point the dish and view al least a couple of FTA satellites.

This bracket has all the LNB situated on a straight line, and I believe that if a bracket could be made or bought to follows the curvature of the dish then there is a possibility to receive more than one FTA satellite, if that is true then, will there be some specific skew that the dish have to be set or follow. How would I or anyone know at what skew does the dish have to be set.

Sorry for all these questions, but I am trying to learn this FTA hobby. I have been a member of this forum for a while, and read some post just in passing, but now that I am retired I would like to do some more fun things with FTA.

I bought the $69.99 six foot dish special, got some help from stogie5150, read some of Dee_Ann adventures now I am hooked.

Well back to the drawing board.

Thank You.

Unless its the only ku dish you have, I would toss that thing and find myself a good sized ku dish to mess around with. Like an old primestar dish, one from a closed store , etc. But if its just a project you want to do, go for it. You never know what you can get working with these little dishes. I have one of the old almost-round 20" dishpro dishes that did really well on 91W. Tough to aim, but worked pretty well for its size.

 

[avenger]

This Dish is about 3'x2', about two years ago I was able to receive one FTA satellite before I put it away,.... about six months ago I decided to use it again set it up on the same pole with the OTA antenna. I am know that this dish is good enough to receive at least one FTA satellite at a time, what I am shooting for is to receive at least two satellites at the same time with some modification to a bracket.

The only things that I need is a commercial or home made bracket with the right angle porpotions to the dish and the right skew angle for the LNB or the dish to do what I want to do. I was just hoping that a member of this forum had done this before with this type of dish, and is willing to explain to me on how he/she did it and how to go about doing it.

Thank You.

They work ok but are not stellar, park it on 97, or 83

 

[turbosat]

avenger I've seen pictures of what you need, but not sure if it was on this forum or some sat dealer. It was made of round pipe or tubing ( remember it looked like chrome tubing maybe 3/4" diameter) and they had some kind of clamp , like a conduit clamp for each lnbf, clamp held to the tubing perfectly. And you could slide the lnbfs sideways for adjustment. Maybe you could fab something like that, figure a way to hold this pipe or tubing to each side of the dish at the correct angle for skew, if the dish doesn't skew in its own mount.

This may be what turbosat was thinking of?

This is the rig Linuxman came up with for his fixed 1.8m Prodelin, there is a thread on the forum that should have more pics and details.

I can take some closeup pics also if you think you might find them useful.

 

[avenger]

Thanks you guys, I was out of town yesterday so I was not able to view the new posts.

phlatwound, that would be nice if you could show some more pictures of that dish/bracket assembly. Been busy doing other things with the grandkids that it has taken some time away from the dish project.

Thank You.

Here is Linuxman's thread with all kinds of multi-LNBF info:

http://www.satelliteguys.us/free-air-fta-discussion/159936-best-way-receive-whole-ku-arc.html

And here's some closeups for you:

 

[avenger]

Thanks phlatwound, very nice pictures of the setup. It looks simple enough, now to ge some material to try and see what I come up with after seing those pictures.

My dish is of a different shape, not too sure but did that pipe had a slight curve bent to it to accommodate/compensate for the radius/arc of the dish, on picture four the left side of the pipe seems to bend forward toward the dish a little.

Thank You.

 

[phlatwound]

Yes, the pipe (conduit) is bent in a curve, and I'm guessing that it is the same curve that a horizontal cut through the center of the dish would form.

 

[turbosat]

That was it Jody, good find. I never would've remembered where I saw that, but sure looks like great work!

reasonable expectations

...what I am shooting for is to receive at least two satellites...

Not exactly the poster-dish for multi-bird reception, but I'm sure you can meet your goal. - :up

Do a search in FTA for comments by member Keith Brannen.
He's got some nice pictures and recommendations for multi-satellite reception.
I think one key is picking two or three satellites that don't need your best-effort to receive.
