Getting Echostar 61.5 and Telstar 11 on Super dish ?

[CoolDmitriy]

Hello gang,

Can I get Echostar 61.5 and Telstar 11 on the DN Super Dish ? My zip code is 19101 (Philadelphia, PA).

I currently have Dish 500 installed pointed at 61.5. I want to utilize existing mast to install SuperDish (hope that Dish 500 mast is compartible with SuperDish). Use DN LNB to get 61.5 bird and linear LNB to get Telstar 11.

If what I just described possible to do, what SuperDish should I get 105 or 121 ? I mean, can I utilize either 105 or 121 LNB to pick up Telstar 11.

While 61.5 ES is high power sat, Telstar 11 is not. Therefore, to get T11 you will need larger dish, something like 36 in.=90 sm. You will need to point that big dish to T11, with Linear LNB mounted in the central holder, and to get 61 ES you can attach LNB for 61ES to this big dish on a side.
You will need to understand the sats coordinates and reflection angles to find the proper position for for additional LNBF. See the picture example how to do it.

"...use DN LNB to get 61.5 bird and linear LNB to get Telstar 11." -exactly.

"...can I utilize either 105 or 121 LNB to pick up Telstar 11?" - yes, these
are linear LNBFs, but I am unaware of their specs. Could they be designed for a higher power sat, and therefore be lower sensitivity? You may try with them, and if necessary, buy better Lin. LNBF.

Adrian,

Thank you for the valuble information. I have one more question for you. Can I utilize the mast from DN Dish 300 to mount bigger dish 35''+ ?
I don't want to drill any more holes in my house :-))) Do you know any big dishes that will work with DN mast ?

Also, what would be the best way to mount DN and Linear LNB togeter other then using cable ties? Are any brakets available on the market for that purpose?

Thank you in advance


BTW, SuperDish is 33''.

Dmitriy,
it is easier to start with what you have already, and then progress further, if necessary. I am not familiar with the Superdish and the mast that you have. If your 33" dish is close to circular shape, you can start with it. If it is not, you will need bigger surface area of a bigger size dish.
I would guess that dishes of even the same size may have different neck
diameter for mast mounting. My 36" has 3" neck size and uses 3" pipe. To accomodate different diameters you can use tubular adapter (like tube-inside-tube) or even some kind of inserts. Obviously, it is all about mechanical strength to support the weight of a dish and/or withstand the wind pressure. Again, start with what you have to receive T11. If you will not succeed, then think about bigger dish.
The brackets for LNBFs can be found in a Hardware store. Look at the link I provided for the idea what to look for.
Two LNBFs will be mounted separately, at some distance.
For Phila, T11 coord.: 30°/140°, ES61.5: 42°/170°. You align your dish for T11. Now, think. Stand behind the dish and "look" at your satellites in the sky. ES is 12° higher, therefore the beam from it will be reflected 12° lower, then the linear LNBF in the center. This sat is also 30° further to the right, so the beam will be reflected 30° to the left from the Lin. LNBF in the center. This gives you an idea where your Circular LNBF will be mounted to catch the reflected beam, and this is definitely not "together". And don't forget to rotate your Lin LNBF 36° clockwise to receive T11.
If you need further assistance, you can send me a private mail.

Correct me if I am wrong but that is only width of it. It is approx. 20" tall.

Adrian,

Thanks a lot. I'll contact you via PM.

Not try to discourage any one here, but trying to get 2 sat with 30 degs azimuth in one dish is not an easy task at all. Some calculation here:
T11 is in center, circular for 61.5 is at a position at 30 degs in azimuth apart from the center (just one side, both side of the arc will be +/-60).
Remember, the typical dish is not designed to get multiple sats at once.
Now reading the Toroidal specs, the dish is specifically designed for multiple sat, and the manufacture claims using this type of dish, one will be able to get the sats within 40degs in arc (+/-20)
If one has time and like to play with sats stuff, it will be a fun project. But for those who never install Ku dish before, my suggestion is don't waste your time. Setting up a fixed Ku dish is still not an easy task to do for first-time users.

Dtsexpert,

I guess you are right about the complexity of this task. I just wanted not to install dish # 4 . Well I think it will be dish #4 soon.

If I want to instal 1.2M dish on the poll. How tall can be the poll?

Thx
