Hi guys, i have pulled my hair out trying to get my offset kuband set up on the arc. I need some help with figuring my elevation angle and declination angle. My zip code is 42240. I get a latitude and longitude as 36.8656N 87.4886W. Iam trying to set up a 1.2meter dish with a superjack positioner. NOT a H to H. so what should my elevation and declination be. whats the best way to figure it up.
Thanks.

Ok this what you can try turn the dish until it is straight up perfectly straight up, now put your signal meter on and tune to the strongest Transponder on 87 w. Now not the actuator but with the mask and turn back in forward until you get something. You may have to play with elevation as well. I just put my 1.2 up a couple weeks ago on my garage. The elevation from the chart that came with the dish was wrong. Let me know how it goes

I've been there. I've been told by someone to enter my zip code and click in motorized. It gives me a elevation of like 30 degrees. Is that correct.

For 87w your elevation 47.2

On 87 try transponder 11812 H. SR 11150 that is PBS and nice strong signal.

Your description of your setup is not very clear.  Before you can say anything about how to set this up, you need to explain what your rotation axis is.  Ie you're saying that you're not using a H-H, which I take to mean that you're not using one of those diseqC motors, that have the rotation axis built into the motor.  So you must be using some kind of a big dish mount or a home-made mount, in which case everything depends upon how you're connecting your dish to that mount.  If you're not using a big dish mount, then how have you created a rotation axis? All you've said is that you're using a superjack actuator
   Anyway, it is not clear at all to me what you are using for a mount.   Elevation and declination can be calculated easily but the question is what do you have for a rotation axis, and what do you have for an elevation adjustment, and what do you have for a declination adjustment???
   The small diseqC motors  generally have a bent shaft that holds the dish (on it's az/el mount) out away from the pole in the ground, and the bend angle along with the elevation angle on the az/el mount work together to define the declination, and the diseqC motor has it's own elevation angle.  But if you're trying to put an offset dish on a prime focus mount, this can be difficult.  We need some photos or explanation of what the setup is.  I think that there is a possibility that without some weird looking connection with your dish attached to a of a bent pipe connected to a polar mount that what you're trying to do might not be possible.

The OP has a Tek2000 1.2M dish and polar mount combo. Anyone know the offset angle of this dish? It's not listed in their specs.

I don't see any mention by the OP of TEK2000, but taking ur word for it, why doesn't he ask them how to setup their antenna?

Take a picture of your setup so I know exactly what you have.

I agree with majortom, that you should get instructions from the seller, however:

What I would do, is to set your angle meter on the top of the square tubing in the center of your picture, such that if the tubing is vertical it would read 90, and if horizontal it would read zero.
Adjust that elevation setting so as that your angle meter reads your latitude plus about 2/3 of a degree, ie about 37.6 for your latitude.
Then aim the mount to true south by rotating the whole mount on the pole as best you can.
Then.... I assume that towards the top there are two loose bolts, and they somehow allow you to tilt the dish down so that it's aiming closer to the horizon?  (The photos don't show what's behind to attach to, but I assume there must be some degree of adjustment there.)  If you can move the dish (not the mount) up/down to find one of the transponder on that true south satellite, then lock it down when you get the best signal. This will set your declination.
Next move the dish west via actuator while looking for a transponder (or signal) on the most westerly sat you can find.  Then rotate the whole mount on the pole by very small amounts, each time observing to see if it improves signal, and peak the signal, then re-peak on that same signal using the actuator then once again rotating the mount on pole.
  Once that's peaked you should be on the arc, so you can do the rest via saving the positions in the dish mover indoors.
  BTW, the above corresponds approximately to the so called modified declination method.

Ok like I said in my earlier posted by your longitude being  87.4886W that means if your DISH IS straight up using the actuator then using turn the whole dish to straight up, now using the mask of the dish NOT your actuator after you have used the actuator to turn it straight up and just set your elevation to 47.2 and using your meter  transponder 11812 H. SR 11150 you WILL GET SIGNAL.. 


Once you do that just fine tune it using a weak TP and you will be in the arc.

Is your pipe plumb?

It is just most important to share the find.
