Jaeger 1224 Installation Questions

dfdream · 10-10-2007

All,

I am adding a Jaeger 1224 motor to my channel master 1.2m dish.
Does anyone have any detailed instructions on the installation and the configuration of the dish.

The questions I also have is .
1: the brackets for the offset dish that comes with the motor have a slot in them. Do I move the bolts in the slots to align the dish or do I move the plate thats ontop of the motor.

See on this page, its the plate on top of the motor

This plate (according to the instructions) is connected to the offset dish brackets and these are connected to the channel master adaptor plate.

See offset section on this link

Thanks

I need some help with this as well - I have the 90cm CM and 1224 and the instructions I got didnt really help me much I would appreciate some detailed instructions on this setup

Take a look at the pic, taken from a members set up here. Should give you a guide to go by. HTH

Thanks for the picture. Ive modified it to illustrate my (and probably dfdreams) issue! Hopefully I havent commited any crimes here

The declination angle is set by adjusting a bolt (illustrated by the yellow yellow arrow). My latitude = 53N which the instructions say set elevation to 36.33 .... Ive done that.

Decl needs to be 6.89. Both the adaptor plate (red) and the offset flanges (blue) can be adjusted which independently alter the declination angle. I have no idea what to have them set to. I aim my dish to 5W and get 85% and then I can never get more than 1 or 2 sats either side of that starting point.

Hopefully someone here has this motor and can shed some light

I really struggled for almost a fortnight aligning my dish attached to a 1224, i followed all the instructions, used a digital inclinometer but could'nt even find my due south satellite. Eventually i threw away the instructions, loosened all the nuts,got everthing sloppy and just waggled the the dish up,down,left,and right slowly, and within minutes i had a signal.I then tightend all the nuts and just used the long bolt and nut on the top plate to adjust. All works very well from 42E to 30w.Hope you get sorted.

thanks - ive been struggling for almost a month now (on and off). Glad im not the only one - I thought the instructions were a joke.

I can get a signal when i mess around with it and loosen sections but i cant get the arc

Ive emailed sat superstore where I got it from and hopefully with their help I'll get sorted

At the moment ive manually moved it to 19East where i get most of what I want. I wont be going up on the roof again till next weekend!!

Been on the roof 50 times this weekend me thinks. Im not going up again unless I have some clue as to what im supposed to do - this guess-work (go up, fiddle around with meter/motor/dish, come back down, go back up is running thin). Fortunately I have a flat (walk-on) roof - if it was a ladder on wall job id have gone mad already

**aba** · 14-10-2007

where you are makeing the biggest mistake is trying to aline your dish up on the roof from scratch no no no
just set a short pole in the ground about 3 ft hight place your dish and motor on the top and aline it on satellites on the ground
when you are happy with the arc set dish on say 30 west hispasat and tighten every thing up
then lift dish and motor together up on to your mount where it will be staying
move the hole lot around till you get 30 west hispasat and you are happy with signal now tighten motor mount to the mast very tight and conect up coax and wires job done

ive been fitting satellite dish since before sky was even heard off sod strugleing on a ladder stand on the ground and do it then when you fit it to the mast where it is going the hardest thing is lifting dish and mount on to mast and turning the hole lot around till it find hispasat ive been setting them up this way for years

i see what ur saying but as i said i have a flat walk-on roof, so in essence- im on the ground when i go on the roof (just a level higher).

whether im standing in my garden or standing on my roof i fail to see what difference thats going to make. (see attachment of a neighnbours house)

have u fitted any 1224 motors on CM dishes before? im assumign yes since you're clearly the most experienced satellite installer the worlds ever seen, Can you please help with how to adjust decl angles?

bobon · 14-10-2007

You said earlier, you setup on 5w and then can only get 1 or 2 sats either side.I think you need to setup on 1W.

**rolfw** · 14-10-2007

Well dependinhg on where you are in Liverpool, you should be initiall aligning on 5W or 1W and allowing a couple of degrees allowance on the motor.

The declination setting is easy to find if you have set the inclination to the correct figure, you use your receiver or a hand meter as finders and adjust the elevation of the dish by watching a portable TV or meter.

I am assuming that your mast is 100% vertical.

***wod*** · 14-10-2007

modk, as you say you have a flat roof are you using one of those roof mounts and is it level

are you using a sat meter as you should be up and running if you are

**TJExcalibur** · 31-10-2007

Just what I was looking for. My 1224 came today and the instructions are a bit brief with the sketches lacking much detail. I spent ages trying to figure out where a couple bits went but the picture solved the mystery.

Pictures never lie mate!

**TJExcalibur** · 12-11-2007

I am just setting up my dish with the Jaeger 1224 motor. As I want to keep my dish as low as possible I was wondering if removing the offset flanges (blue) are required. Can just the adaptor plate (red) be used on its own. This would mean my motor is set more horizontal and the dish lower from the bedroom window.

The angle of the motor is the most essential part of tracking the arc, this must be at the correct angle. In your case approx 39deg from horizontal, (90deg - 51deg for bournemouth.)

How you mount the dish to the motor, to get the correct dish angle is up to you and the brackets/ facilities you have.

Not in order to keep the dish lower, but because I dont like overhanging loads, I shortened the bottom bracket of my 1224 and redrilled the mounting hole. There is a limit to how much you can shorten it and still clear the motor as it turns.

Looking at your pic., I don't think that this will give you what you want, but you could make/get made some triangular shaped plates that would lower the dish and not need the top linking brackets.

**TJExcalibur** · 12-11-2007

Thanks but its not my pic, one from a previous post in the thread. I wanted to kep it more compact, without the extra brackets it would mean the motor is more horizontal and the dish is bolted more at a right angle to the motor. I can only try it and see.

**rolfw** · 12-11-2007

The motor elevation angle is purely determined by your latitude, making adjustments to the dish bracket cannot change it.

***wod*** · 12-11-2007

i think you need the extra brackets as i was playing with mine and it didn't leave much adjustment for the dish i thought with adapter plated bolted straight to the motor

all the pictures i've seen have all used the extra brackets ?

**TJExcalibur** · 12-11-2007

The 1224 install instruction have no mention of the extra brackets and show a drawing of the dish plate fitted straight to the motor. I can try and see, if not its no big deal to refit the brackets.

***wod*** · 12-11-2007

i was hoping to use just the plate as the elevation of the dish i don't think need all that much once the motor elevation is set correctly like in the pic of johnsattuk

i wonder if they are for prime focus dish or something

**TJExcalibur** · 12-11-2007

I was thinking the same but in the pic of johnsatuk he has a triangular bracket with the motor on an angle but the dish is almost vertical. Is there a reason why johnsatuk has the motor set at an angle then a plate fitted to make the dish almost vertical. Why not do away with the plate and make the motor parallel with the dish.

A prime focus dish would not need them, since the dish angle is something like 25deg from vertical. Might even need them at the bottom.

As I said previously, the motor must be mounted at the correct angle for your lat. if you are going to track the arc.

**TJExcalibur** · 12-11-2007

OK its like this then. If the motor is parallel to the dish it would not be possible to track the arc. So the brackets allow the motor to be set at the correct angle and the brackets are the adjustment for the offset dish. Must admit I am unable to see the difference but the proof of the pudding etc......

If your motor is horizontal, it will track a straight line in the sky, which if you were lucky may possibly pass through two sat. positions.

If you were on the equator, you would need to set your motor to vertical, pointing due south or north since you are in nomans land, and set your offset dish leaning backwards about 25deg (average sort off ofset for dishes) and you would then be able to track the sats.

As you are not at the equator, you need to set your motor to suit the lat. you are at, pointing due south when at the zero position.

You need to apply a correction for the curvature of the earth, (about 7deg for these latitudes) added to the offset angle of the dish. This gives typically 7deg + 25deg = 32deg. You then need to tilt the dish forward 32deg. This is approx the same as the inclination of the motor, and is why the dishes are close to vertical when at the top of the arc.

The dish will then track the arc, and will automatically apply the right amount of skew to the LNB and dish

The two things which can be measured and must be set accurately are the inclination and due south. Because of manufacturing tolerances, difficulty in measuring/knowing the offset of the dish, mounting position of LNB etc. some degree of fine tuning is usually required when finally setting up, but if you have set the motor accurately, all adjustments should be on the dish mounting.
