Are polar mount setup instructions included together with actuator?

If you live outside the reception footprint of a satellite and would like to, or can already receive services, post your questions or information here.

very nice .....dish.... bombedone... and the parabola's not bad either

and lets have no double entendres about ...the focal point.

I can't believe she is 2.4m tall.

(Nice curvature though)

She may have the dish behind her, but I've got the horn

It does, but you do have to search a bit for it

Setup the Dish

Post 10 should have more or less everything you need, and if not, come back here.

Yes, post #10 seems to be enough. Btw, I can set-up live video broadcast from my roof, when I'll be installing actuator, so everyone can watch and give suggestions online, if something goes wrong. Finding maximum elevation angle is also quite easy, since my longitude is 44.49, I can use Intelsat 12 at 45E as centering aid.

Today I also found a company, which can do installation for me. But their price is too high - $200 just for dish alignment, not including metalworks for straightening the pole!

Good luck, is it as cold there as it is here ? (-5 degrees at the moment )

yes, it's quite cold (for us). Everyone talk about global warming, but here we can clearly see in latest years, we're getting local cooling weather becomes more damp, with more rain and snow, winter becomes colder, summer becomes cooler...

and regarding setup instructions, they are to be used in case, when pole is perfectly vertical. But what, if it's not? how I can compensate that?

Small additional adjustments in elevation, North-south and declination are all you need to make up for a non vertical pole.

My System: 75e-75w C & KU, 36v h-h /36v & diseqc actuators / diseqc -USALS motors / Anlg to HD Channel Masters C120s dishes, stb's inc echo3000, lnbs, meters, custom polar mounts & elevation/incline actuator conversions...

You can use an inclinometer/clinometer on the polar angle and ignore the markings....
but..
The lean must be 100% north<>south though ... really not easy that. The only way I could see doing that, that accurately is to line the dish up on 45e- ... set the polar mount to 0.5w and move the whole polar mount around on the pole and the dish elevation up/down without touching the elevation or the 0.5w azi' setting on the polar mount and then see if the polar mount is then 100% in line with the 'lean' .. otherwise I would refab it straight... (or use packing under the bolts to level it).

Unfortunately, there's no way to install packing under pole, since roof surface cover is quite thick but foamy, so unless pole deadly mounted to it, it will shake.

I've developed scheme of balancing plate, which will avoid me welding works for the pole. Now I'm drawing it, will post a picture later.

KingPost may be good, but I can't do such technique by myself - it will require me to bring down the pole from the roof, or use welder directly on the roof, which is prohibited.

no, but we can make big dish mounts etc. so I know the problems.

I am sure you make it strong for the job BombedOne- it‘s difficult to see from photos…. Thick wall 75mm-100/3 -4“ pipe, good channel iron, good welds etc..
....what size bolts/ threaded bar and how many are bolting it down?

If we do a 2.4m and it is a solid dish it is 150mm / 6 inch pipe schedule 40 for shorter pole and schedule 80 for longer pole .. but that is a lighter C BAND wire mesh dish and the polar mount is designed for what looks like about 75mm -100mm/3-4 inch pipe and the pole isn't too long. I don’t know about KU band mesh on that roof though- never used it.

Polar mount says that it's designed for 75mm pole, so I had no other choice. Pole length is 1.5m, I'm planning to cut it somewhere at 0.5m height from base, and install balancing plates there.

Regarding threaded bars, I don't know which system this is, but we call them "M8" thread, and use "13" hex key for screwing. Currently there are 4 such bars, but holes are drill for more 4 units to be installed.

After all adjustments will be finished, I'm planning to put some rebar inside that pole, and pour in liquid concrete.

I've did another drawing, this time 3D, to more simplify understanding of my approach (actual proportions of components aren't preserved on this picture, to allow more simple understanding).

1. First, I'll cut off my pole (yellow on pic) , using grinding machine (most hard part)
2. I'll take pieces (green on pic) of steel sheet sized 15X15cm (what thickness will be optimal? 5mm will be enough or not?)
3. Will weld L shaped steel stripes (pink on pic) to it, to match pole outer diameter (there will be 8 such stripes, not 4 as on pic)
4. These L shaped stripes and pole will be drilled, and apropriate length bolts put trough it, to nicely secure whole construction.
5. I'll repeat such operation for both parts of the pole
6. Next, I'll drill 4 corner holes in both plates, and fit bolts, to have vertical adjustment

what do you think?

4 x 8mm.. I would increase that before you fit the KU mesh... I would get to sleep with 4 x c. 16- 20mm threaded bar... & not same as 8 x m8.

good idea... 75mm can be solid.. depends on wall thickness and steel type but 75mm on solid 2.4 ku and you would have to do something like that too.

would like to see the ku mesh and what that does to the wind loading... obviously the dish will not get that much wind loading with that c band mesh now..

what do you think?

all sounds good.. but picture not there.. edit... it's there now...

cutting wheels on hand grinders are very good now for cutting quite big steel... (bit dangerous when they shatter though) .. we used to have to cut more with burning torch on site.


edit...

I see drawing now..

have a look at pipe flanges... you can cut and weld 2 on... use spacers to adjust (washers) ... . you could even add bolted bracing later using the flange holes if you needed extra bracing.
