Conical Scalar Ring Test Results

[Anole]

Well, it goes without saying, that the LNBF throat needs to be in the proper position in front of the dish.
That puts it at the one correct focal point, where the dish works to maximum efficiency.
A way to test, is to assemble the dish properly, aim at a known satellite, then reassemble with the C-band LNBF, and make sure the elevation doesn't change.
Alternately, make sure the elevation marks on the bracketry (if you are using the factory hardware) agrees with real satellites you see after putting on the C-lnbf.

But, just to take some more variables out of the equation, don't make any assumptions as to which satellites you should/shouldn't get.
Probably ones with no nearby interfering birds are your best bet.
So, use a list that is proven to work.
Here is what Linuxman found on a 1.0 meter Channel Master dish, so it should be a guide to go by:

edit:
A 1.2 meter Channel Master should be hot stuff!
You are fixed, not motorized...?
So, that brings in another variable: skew.

When I was fooling around with a 1M mini bud that's what I did. Aim at a known sat with a ku lnb and then switch to c-band.

In my case I aimed at G16 99W. Though, in order to get c-band reception to work I had to lower the dish about 5 degrees. Would you have an explanation for that?

 

[PopcornNMore]

G17 is 6 degrees away (91 to 97) and you should get KCSG just fine. I did on my 1.2m dish/conical ring

1st pic is KCSG and last ones are G17...Pansat 1500 reads pretty true. 30 is threshold in most cases

Sorry, I meant to say Galaxy 16.

Thank you for providing the screenshots.

 

[PopcornNMore]

they have some magical powers helping them


eh not necessarily. Stuff on AMC1 & AMC3 I can lock with the 6 footer and not the 4 footer

I have a challenge! I'll see just how well this CM 1.2m performs and will provide screenshots.

 

[PopcornNMore]

What's the f/D for the Channel Master? The conical scalar may be limiting the portion of the dish that the feed can see. Also, did you check the focal length to the bottom of the dish?

Great tips! I'll check.

I am motorized on the 1.2m CM.

I found KCSG!!! Thank you Iceberg.

Now I can get my Dennis The Menace fix.

 

[PopcornNMore]

We had thunder storms tonight, so I wasn't able to work on the dish. I saw that Iceberg also has the throat of the LNBF deeper inside the scalar ring (photo attached) as previously suggested. I will take Anole's advice and will try this tomorrow night after moving the flat scalar ringer further away from the dish.

glad its working for G19

KSCG is a great channel. It has some programs like Happy Days and Bewitched not found on other MY Network affiliates.

My Pansats would routinely skip finding it because of KSCGs relatively low SR. I always had to manually scan for it during setup.

KCSG is only a My affiliate during prime time. The rest of the time they are an Independent. They've even skipped showing movies on Saturdays for other programming

Great channel, but for now the audio breaks up with a 67% signal. However, the video remains clear. Once I tweak the setup it should come in better.

This afternoon I pulled the c-band LNBF further away from the dish and started receiving additional channels such as the FOX channels on Galaxy 17. I also noticed that KCSG comes in as a horizontal channel instead of a vertical. I believe someone mentioned once that the GeoSat C-band LNBF must be mounted with the zero pointing at 9 o'clock instead of 12 o'clock on a motorized dish for whatever reason. I will try turning the LNBF tomorrow and then re-adding the conical scalar ring.

Both the Geosat CK-1 and C2 need their "pointers" at either 9:00 or 3:00 . Strange , but my new C2 is the same way.

 

[Mr Tony]

yep same here

All my C2 units are set at 9:00 for 0 skew

Here are a couple of things I keep bookmarked:

Too late for you now, Popcorn, but maybe the next guy reading your thread will get benefit from this fine post.

Already answered, but the pictures are always nice to look at -
One of these days, someone should compile pix of all the popular LNBFs in one place.

Thanks Anole, for digging those up!

I adjusted the Geosat LNBF so that the zero would be at 9 o'clock. This corrected the polarization, however some of the channels no longer came in as good as when the zero is at 12 o'clock. I will need to play with it a little.

I have to play with the skew occasionally , if I want to optimize a particular signal. STO HD comes to mind, on a hint from Iceberg. Nothing's perfect, I guess.
You might want to look down the feedhorn, and see that the probes are actually where the mark says they are.

 

[PopcornNMore]

The Geosat LNBF i'm using is C-band only and was purchased from Satellite A/V that time he had that great deal for us Satellite Guys.
