Gibertini polarmount settings

[Archived-1]

I have tryed some apps on the iphone but as soon as I get near the dish it goes haywire.

TBH you are better buying the correct item for the job.

Got an inclometer in the post. But I quite agree.

Finally have it tracking 47.5e to 45w at the moment with the ku band lnb. :-)

So was the elevation of the mount wrong in the end?

 

[Archive-8]

Yes it was, got the inclometer in the post, and re-done it. To your maths. Thanks :-) now I need to tweet my c-band lnb as not getting the same results as I was on my other 1 meter dish. But I can play with that in my own time.

Many thanks for your help.

Something wrong here. Correct polar mount elevation for your location is 38.8º. Declination is 6.7º. If you subtract the declination from the elevation it will give you the elevation of your due south satellite. 38.8 - 6.7 = 32.1º. Just looking at the mount in the photos looks wrong. It looks set up pretty much the same as mine and I am 12º further south.

It's possible the whole polarmount assembly has been fitted upside down on the pole.

Not according to the photo.

I don't think it is.

Is there a web page or some thing that will give me the chance of being able to look up the elevation and declanation values?

You can start with
http://www.geo-orbit.org/sizepgs/tuningp4.html
http://www.geo-orbit.org/sizepgs/decchartp.html
... and then the fine-tuning of the angles can be done with an angle grinder.

Thank you for the links.

 

[Huevos]

My figures are good, but anyway you perfect this using your meter, not an angle gauge. The angle gauge is just a helper to get you in the ballpark.

I asked as I have another dish to tweek. Using your maths worked a treat. Thanks again. :-)

I've got one of those c band lnb's waiting to be installed, isn't it upside down? I thought the skew markings on the back should have the zero pointing almost straight up? just curious, going to have go with mine if whether is ok at the weekend, which it probably won't be as it is a bank holiday

 

[satsid]

whether weather? its all the same

With circular polarisation, it makes no difference but with linear, the 0 degree line should be pointing downwards. On mine, this makes the heatsink appear at a 45 degree angle.
