Advice Needed Who can reach 72.1E

[Archived-1]

I am wanting to know how many small steps it takes from peak signal on 62E to signal on 72E with a standard actuator with no modification's done to it please.

Thats impossible to say mate..
Depends on the actuator ..the pulse count ..number of magnetic hotspots on the wheel that activates the reed ..
the distance the motor is fixed laterally from the pole centre ..
The side of the dish mounted on ..E or W ..
ie is the actuator at full extent driven Eastward ..or Westward ..etc
Each setup is different.
For example on Christina ...the actuator is mounted on the West side ..thus fully closed at 58W ...
at this point roughly 20 clicks per degree..
approx 10 clicks at the arc peak at 1 West ..but fully extended at say 62 East ...where the pulse count is roughly 4 per degree ..
you get the picture..

The exact opposite woukld be true if the actuator was mounted on the East side of Christina.

Thanks VS so if I work on 4 degree per click I wont be that far wrong, I just need to get this as accurate as I can,

Depends on the length of the actuator and which side it is mounted ..
When in doubt I usually find the closest 2 known sat positions to your unknown target..and count the pulses between those known 2 ...
then use this as a reference ...if say the pulses number 20 and the sats are 4 degees apart....then its roughly 5 clicks per degree..
good luck

Thanks again VS, I've just been out and taken a few more pictures and made a decision where to dig, if I cant get what I want with one dish I will have to move the 1.2 to the front garden/top of my back garden end of story I've done all I can now.

Thanks again for the information .

I remember there was a thread here somewhere (yours, I think, Evan) where Huevos did just such a calculation. He needed measurements from various points at the back of the dish to work this out.

Yep ..I know what you mean buddy ..and I'm in a similar situation in many ways ..
to get at extreme East ..I have to link to 'Dick' ...a usals driven TD88 mounted at the rear of my Dads house ..3 doors down from me ..
The lengths we go to eh ...
Just a quick word of advice mate ..
If your dish has a restricted view of the extreme Western arc ..but clear to the extreme East then mount the actuator on the East side of the dish ...thus fully closed you see your Eastern limit..
Reverse this if the opposite is true..and mount on the west side fully closed..

Yep ..I well remember it ...
Huevos knew his stuff with regards to the trig calcs

I don't think I will have a problem as long as my dish face has a clear view of the gap in the houses, i just wanted to hit everything with one dish,

This is the height the 1.8 will be at to the base of the dish the same height as my 1.2 now,

Here is a picture of the 1.2 lnb one picture is looking up at it the other is looking down, the 1.8 arms are longer so the lnd will be higher.

The camera is sat on the dish arm for the looking down picture and put to the bottom of the dish looking up ive tried to keep it as straight as I can,

So all I can do is locate it so the full face of the dish hits the gap in the houses, what I get I get, if I do have problems I relocate the 1.2 to get what I am missing .

The dish is pointing at 62E,

Hi, I am now locking 66 68.5 and 70.5 E anyone locking data in KU band at 72.1E please.

I do not think you can lose much more.
Remember that these positions are flush with horizon and photos from the antenna, the houses of the neighbors are higher.
I have a wall of 125cm, 30cm antenna protrudes just above the 61ºWest amazomas to signal very very fair and teammates could tune 80cm well, on the other hand I prefer to 57tºEast this for the same problem.
For the Astra to 19'2ºEast this if you stand in front of the antenna above the 12-13horas (Madrid), if your shadow does not touch the LNB signal passes over smoothly.
With these ends satellites, obstacles must be below the antenna.
In an imaginary horizontal line.
-----------------------
No creo que puedas bajar mucho mas.
Recuerda que esas posiciones estan a ras de horizonte y por las fotos desde la antena, las viviendas de los vecinos son mas altas.
Tengo un muro de 125cm, la antena apenas sobresale 30cm por encima, el amazomas a 61º Oeste muy muy justo de señal y los compañeros lo podian sintonizar con 80cm bien, por el otro lado me quedo a 57º Este por el mismo problema.
Para el Astra a 19'2º Este si te pones delante de la antena sobre las 12-13horas (Madrid), si tu sombra no toca el LNB la señal pasa por encima sin problemas.
Con estos satelites extremos, los obtaculos tienen que estar por debajo de la antena.
En una linea horizontal imaginaria.



PD:

Just for info; Not a very good from my QTH with 1.40m dish.
low and high KU band in H (no problem in Cband with 3.10m)


PS: @satesco can reach this satellite easily .

PD:

Not another one , I am totally aware that this satellite is on the brink, if I don't try I will never know, if I listened to peeps I would still be only getting 62E,

Thank you FS, that's all I asked

Hi I am locking this slightly E of 70.5 E, I cant lock anything in at 70.5 when this is locked in and vice versa 12593 H 8500 Tagged PR2510 would someone confirm its position please.

 

[Captain Jack]

How many clicks from 70.5e do you have to do to get the lock on that frequency?

 

[zorbua]

Tried whereabouts of 70.5E but nothing seen with a 1.5Dish apart of course 70.5E itself.

 

[Anonymous_1]

72°E, mobility beam (1.40m antenna)

 

[zorbua]

Cannot receive any ACM/VCM 0r 16APSK etc.etc.

 

[Archived-1]

How many clicks from 70.5e do you have to do to get the lock on that frequency?

It was about six small clicks E Alex, I lost all signals at 70.5, and I could not lock the TP at 70.5 ?, I will move back over and see if I can lock it in the day time.
