Best Set-up?

[Robert_W]

It will not happen again. (Thread-jacking)!!!
And thanks to those who gave me insight to get going. I am excited to get started.
I hope that tri-pod will work. The Fortec 90 CM will not be too flimsy, and everything stays solid to get my 'True South'. Then hopefully get the Clark Belt aligned. I just hope I can get a signal from the 91.0 W satellite.
Thank you all.
Robert

 

[Robert_W]

I will not do it again!!! Thread Jacking!!!
Thanks to all for the help, and hopefully this Fortec 90 CM is correctly put together, and install it on the H-H, and the tri-pod will keep sturdy (until spring) and get this system up and running.
Thanks to you all!
Robert

Dish alignment Web-INFO

Today, I was reading about alignment of the C-Band Dish. I was wondering if this procedure will work with a 90 CM?
Since I am still newbie, I am going to try to post the link.
Footprints by Dish Size - Adjusting the Polar Mount for Prime Focus Antenna - C/Ku-Band Satellite Systems - Tuning, Tracking, Azimuth, Elevation, Declination Angles, F/D Ratio, Focal Distance, Inclinometer, LNB/Feedhorn Assembly, Actuator Assembly, C

If this works with all types of dishes, then I might have found the most useful alignment tool of installing my (and anyone's ) dish.

 

[Lak7]

One thing different when setting up a Small Ku Dish, you do not set the Declination as a separate step. But the rest is the same.

There is also a book....
The Home Satellite TV Installation & Troubleshooting Manual English

Installation guide

Robert -- Sadoun's website (see sponsors at top of page) has a clear guide for installing a motorized dish. That site's instructions will probably be less confusing than the c-band installation guide that you found. Your setup uses a horizon-to-horizon motor; the c-band guide describes setup with an actuator arm.

Moteck SG2100 Set-Up?

There is Elevation, and Latitude.
Which side to use? And if one side set, what would the calculation to set the opposite side?

I am now at 40.76 N, 91.72 W

Dish Setup Data
Latitude: 40.7591°
Longitude: -91.7191°

Name: Moteck SG2100​

Distance: 37568km


Motor Latitude: 40.8°
Declination Angle: 6.3°
Dish Elevation: 24°
Elevation: 42.9°
Azimuth (true): 180.0°
Azimuth (magn.): 179.8°
LNB Skew [?]: -0.0°

Dish Skew [?]: 90.0°

I see that my dish will have to be set at 24 degrees.
Motor Latitude is 40.8, so what will be my Elevation on the SG2100 be set at, to be plumb/level with the 40.8 Latitude? OK that is answer below at 49.8 'Elevation angle' below; but 42.9 in above calculation!

This is a 30 degree declination angle for the dish!
Elevation And Declination Angle Table has:

With figure, My Declination Angle is calculated to give me answer for my 'Dish Bracket Angle'? DBA is set to 23.7, and ready to scan , Right?

 

[Mr Tony]

Use the latitude side of the motor and set the latitude to the same as your latitude (40)

Sorry I had to put this in quotes but want to make sure I understand all the questions before I reply. Iceberg is correct, use the latitude scale on the motor and set it to you latitude, round off the number and that comes to 40.8 degrees on the motor scale leaves some what room for desire. Again when it comes to your dish elevation setting round off the figures, so 41 would be closer and use the 6.4 degree figure, subtract from 30 degrees (the motor tube bend) and you end up with 23.4 degrees setting on the dish elevation scale. However no dish scale is ever 100% acurate so plan on possibly tweaking the dish elevation later on.

 

[Tron]

Skew on a motorized dish is '0', or no twist on the LNB (the LNB is straight up and down). The motor skews the LNB and dish automatically, because of the bend in the mounting shaft, as it moves across the arc.

OK,,, I have the Invacom qph-031 installed. with it 0 degreed, Now I notice that the LBN needs to be connected to the DiSCqC Switch before the motor.
Where should I place the 4 to 1 DiSCqC at? And do I really have to connect all 4 to Switch? (According to instructions, from the back side, it only requires the right two terminals 'L & C').
I have each Terminal
Vertical OSC 10.75GHZs,
Horizonal OSC 10.75,
LHCP OSC 11.25,
RLCP OSC 11.25

About the DiSCqC,,,,, can I place it on the LBN Arm? or shall I take the 2 or 4 cables and run it all the way to the DiSC nailed to wall, then run it back to the SG2100?

I was kinda thinking of Sheet metal screw to arm, then run back to motor. But I do not want to have the arm throw off the LBN nither.

 

[krisman]

i have my discqc inside a plastic ziplock bag taped onto the side of the mounting pole and 3 holes slit in it to run the wire into the c and l ports. u only have to have one cable to the c and one to the l, then one more cable from the "receiver" port on the discqc to the "lnb" port on your motor. then a cable from the "receiver" port on the motor to the receiver inside. at least thats how mine is.

 

[walrus1957]

Krisman is correct, always place the switch between the motor and LNB. There should be no switch between the motor and receiver. I know of others that split two different otorized systems using a SW21, one output for each motor and it works, but this is not recomended.

 

[Robert_W]

Thanks Krisman, and Walrus.
Ok I did place one to the L and C, to the right side according to instructions.
I thread the coax and put a small drop on the line, then back up onto the arm.
Ran it on the arm, right up between the brackets sides, between the dish and bracket.
I put on boots, Eletrical Tape on the LBN connections to the 4 to 1 DiSEqC, and the 'to receiver' I did not have a extra boot, and seems that I should not have to ever remove it, I used liquid tape on that connection. Then just used a cable (plastic) strap and just hanged it from the H-H SG2100 moter's Pole clamps.

Krisman, how did your Arc Work out. I know I will be off a .72 degrees from my 'TRUE SOUTH' meaning my 91.00 west sate will be .72 degrees east of my 'TRUE SOUTH'.
I do not know if there will be a big difference, but 3/4 of a degree off might over-under shoot some satellites in the lower horizens.

Well going back out to connect the 4 to 1, to the H-H. It is about 11 degrees temp, and a 10mph wind. So little cool on the bare fingers.

Robert, there is some cofusion here. Krisman isn't off 0.72 degrees, he is spot on, otherwise he wouldn't be able to track the arc. As to what is related to true south isn't what everyone thinks it means. It has to do more with aligning the top of the arc as close as possible to the nearest true south satellite. I am trying to say this that everyone can understand. As long as everything was set correctly ahead of time and you are mounted to a perfect plumb pole, once you do your initial setup aligning to the top of the arc everything else comes in. The top of the arc is the best point to start the alignment process and will provide the results you need to determine what might be wrong with the dish elevation setting, the motor elevation setting, the azimuth setting and if there is any lean to your dish mounting pole.

For good test results of top of the arc alignment, choose the nearest Linear satellite to your due south location that you can get a strong signal from and a known active transponder. If this satellite is within +/- 5 degrees of true south it will work just fine. But try to stay within that limit of +/-5 degrees. Go out of that window and you start to skew your test results.

Question below for drive motor:

OK,
I have the QPH-031 hooked up, L and C, port 1 and port 4 (which one where, do not know). From disqc to Motech SG2100.

I put a Satellite Finder ('Steren' model 200-992) in between Motor and receiver.
I hooked up the SV 360 Premier and turned it on.

Just like Krisman, I had the 0 Quality. But signal strength (Which is nothing according to his post) So I moved ever where. dish elevation, mast clamp (where motor is hooked onto). I did not even get the satellite finder to move.

So I put everything back where it needed to be set. I might not have the Nimiq 1.3 (Nimiq 1) cordinance right.

So it is dark now, and ceased work tonight on it. But I went into the Dish Setting, got Satellite Nimiq1.3 for 91 west up. I went to motor set-up, and set the latitude from my area and Longitude also from my area ( from dishpointer.com)

I being at 40.76 N 91.72W The Latitude it gave me was 42.9 N, Long 178.9 W. So I put that cordinance into throu USALS.

So once I get that quality signal peeked about 80 (With other posting states on that satellite) I should have my arc set, right? I am setting my elevation on the dish ~23.5 (as this fortec 90 cm is hopefully not bad) and the arm looks good the Elevtion for the moteck is set to the ~41.

So with this cordinance set in for the USALS, how do I drive the motor to get to that place?

I have no help for some one to yell at me. So how much a jump on this sat finder will I get when hit the signal?

 

[Lak7]

I have the QPH-031 hooked up, L and C, port 1 and port 4 (which one where, do not know).

Try to take a look and see which is where, makes life easier.

40.76 N 91.72W

If this IS you correct Lat and Long, that's what you enter in USALS.
"178.9 W" is where you point the Motor Mount to using a Compass.

So with this cordinance set in for the USALS, how do I drive the motor to get to that place?

That's the beauty of USALS. When you want to add a Sat, enter proper LNB & Switch settings, select USALS for Motor, double check the Lat and Long info (you should only have to enter it once) read the options there, you should see something that says "OK to Move", "Go to X" or "Go to Reference" usually drives the Dish to "Zero" not to the Sat.

Remember that you Must have an Active / Live Transponder selected for the Quality meter to Light Up!

Quote from Lak:

OK, if I am at 40.76N, 91.72 W. And Nimiq is at 91.00 W. And Why am I entering those cordiances to "That Satellite" When I will be off .72 degrees west of Nimiq 1?

So when I set up USUALS, I need to have my Moteck SG2100 set at '0' then add the 40.8 and 91.2 to the SonicView 360 Premier?
The USUALS looks like it can be placed in the "Certain Satellite'.

I hope to get the Nimiq 1 this morning.

The SonicView has 'Move" but I did not see 'goto X, But it does have a 'limit'.

Correct, if the Motor is at "Zero". To tweak, have the Receiver "drive" to Nimiq using USALS, it should move for just a split second, then twist the Whole Thing back to peak signal. That should make up for the .72 difference. Next is to setup Galaxy 17 at 91, used to be called Galaxy 11.
Use "The List" at the top of the SatGuys web page to get the Strong transponder for Galaxy 17, enter that info manualy if it's not there already, and peak again. Do not use the receiver to "bump" the Dish, only mechanical adjustments and drive via USALS.
Don't forget to set the Switch properly. I'd connect Port 1 to "L" and port 2 to "C".

Robert_W,

Just a small note to add, looking over what you wrote:

"I am setting my elevation on the dish ~23.5 (as this fortec 90 cm is hopefully not bad) and the arm looks good the Elevtion for the moteck is set to the ~41."

Hopefully your not confused here. Your latitude is 40.7+ degrees, DO NOT use the elevation scale of the Moteck motor, DO USE the latitude scale of the motor and set it to 40.8 degrees.

 

[Robert_W]

Be Back in 10 minutes.
I am going to see if 40.8 on Motor scale. and taking the inclometer out to see if I am at 23.7 degrees on my Dish (Measuring inbetween the dish mounting bolts.

And puting meter on the 'L' Side of the QPH-031 or the C side for Nimiq 1? And having my motor set at '0' scale "to the highes level for peak of arc) then by-pass motor so:
Reciever > Scale >Lbn C or L side?
