Super Dish With Digiwave LNB

[Apprentice]

The Digiwave mounts right up on the super dish. I measured it all out and the Digiwave mounts and looks right down the same spot as the FSS LNB that was front and center.

I will mount up the dish soon and see how it works. Might make a decent fixed dish setup

What is the spacing on the original for the FSS and DSS LNB's ? I am guess it would have to be 4 degrees Since original DN setups for this area are 105, 110, and 119. I wonder if i can modify this bracket to add more Digiwave LNB's to the super dish?

I just finished motorizing a superdish and am amazed at how well it works, BUT, in my application at least, I found that the actual "sweet spot" is not straight ahead as I imagined. I had marked the spot by sighting straight down the arm and it looked like that should be fine, but it produced disappointing SQ. I hooked up a meter and got max SQ by mounting the LNB using the right existing hole, but pointing the LNB left. Why? I don't know, maybe the arm isn't square to the dish, maybe it was designed that way? All I know is that is how it worked out in my application.

The SD LNB"s were severely modified to work properly. The 105/110/119 ones were the best as 2 LNB's were 5 degrees apart. The 121/119/110 were set up differently with the 119 LNB literally looking like a crayon tip (to get 2 degrees away)

You should be able to get 2 sats 4 degrees apart but with the SD being on the small side to begin with the results may not be the best

Wow I would not have guessed that at all. Since the FSS seems to be centered. I will try it the way I have it. Can always change it to your setup if it does not work. I have two DN super dish one already setup. Thought I would change the LNB on that one and point it to 97W. Good to know how you did it in case I have to change it

Thought about putting a motor on one of the super dishes but not sure. Maybe the second one that is almost setup I could try that with.

Thanks

I will probably stick with single dish setups on the DN dishes. But since I have them might as well use them if I can. They are a dime a dozen around here. People are always throwing them away.

 

[Mr Tony]

why dont you use the stock LNB that is on the SD?

The 105 LNB works just fine for KU Band

 

[Apprentice]

Well i want to feed two STB units and did not think I wanted to try to figure out the possible bandstacked issues. I may go back to it if this causes me issues.

On second thought maybe i should just repoint the present SD at 97W and see how the 105 LNB works before changing it?

 

[Mr Tony]

Bandstacked allows you to run multiple receivers off one coax since all the frequencies are vertical polarity

This is one of the few times a high frequency splitter works

 

[Apprentice]

cool I will just repoint the current dish to 97W and see what happens. Rain coming in today so will have to wait till tomorrow.

OK so I did not just repoint the current DN SD. It was a really nice day here and I felt like messing around outside. So I just took off the SD with the FSS LNB on it and replaced it with the one that I put the Digiwave LNB on. I was nicely surprised at how well it seems to be doing. I just pointed it at 97W my true south sat. I am getting quality readings on the AzBox of mid 60's to high 60's. Not too bad for 15 dollars on the LNB and some time

Oh and I did leave it pointing dead on like the FSS LNB was originally. I guess I might get a better quality by offsetting it like you did Skyscanner. But since it seems to be just fine I think I will leave it and maybe test the offsetting the LNB on one of the other super dishes.
