Es'hail 2 25.8°E channels

[moonbase]

Not much has changed 'ere on Es'hail-2 at 25.8 East, still locking the MENA beam frequencies.
However, the bein frequency on 11350V is at a reduced level today compared to scans a while ago.

A list of locked frequencies from the MENA beam and a few screen shots are below.

01. 10730H, SR30000 (El SharqTV)
02. 10730V, SR27500 (Al Rayyan)
03. 10770H, SR27500 (Alkass)
04. 10770V, SR27500 (Qatar TV)
05. 10850H, SR27500 (bein)
06. 10890H, SR27500 (bein)
07. 11310H, SR27500 (bein)
08. 11390H, SR27500 (bein)
09. 11430V, SR27500 (bein)

I managed to lock the 11350V bein frequency by nudging the dish 6 clicks East, corresponding to about 0.3 degrees.
That might possibly suggest that 11350V is not coming from 25.8 East or it could be an artefact of fringe reception due to my location being out of the MENA beam footprint?
It is the only frequency from the ten that I locked that increases in signal level by nudging the dish East, all the others lose signal level.

The updated list of locked frequencies from the MENA beam and a screen shot of 11350V are below.

01. 10730H, SR30000 (El SharqTV)
02. 10730V, SR27500 (Al Rayyan)
03. 10770H, SR27500 (Alkass)
04. 10770V, SR27500 (Qatar TV)
05. 10850H, SR27500 (bein)
06. 10890H, SR27500 (bein)
07. 11310H, SR27500 (bein)
08. 11350V, SR27500 (bein - new upload)
09. 11390H, SR27500 (bein)
10. 11430V, SR27500 (bein)

You could be shifting away from a sidelobe of the dish collecting 11.344V on Astra 2 (also horizontal on the same beam).

I can get both transponders here on the 35cm portable dish almost half covered with a wet towel, I estimate the two beams are above 60 dBW in the London area.

Thanks for that.
¿Posible 'MB' that you could advise the image and skin that you are using with the screenshot?
Appreciated.

Yes, good point, I initially thought that it might be from 28.2E.

However, when I scanned in the channels to get their names they corresponded to the bein mux that is listed on Lyngsat and Flysat for 11350V.
The picture attached above in post 22 of "bein movies 3" was from one of the channels that locked when I scanned the frequency.

I think I may have not have initially grasped your point about the side lob correctly?

Reading it again, I think you were saying that when the dish is on the true 25.8E position my 11350V signal is getting battered by the 28.2E side lobe. Moving the dish away from the true 25.8E position escapes the battering from the side lobe and I have enough signal remaining to get a lock.

Seems obvious now, thx.


On a slightly related matter, I wonder if this side lobe battering could be impacting reception of Es'hail-1 at 25.5E, a notoriously difficult satellite to lock from a UK location.
I need to try this offset nudging to see if it has any impact on reception from 25.5E.

I can sell you a better dish.

 

[moonbase]

I can sell you a better dish.

Install the dish for testing and if it can better the signal levels for a selection of satellites compared to the dish I have 'ere I will buy it, subject to asking price and it being within any size limitations I may have for installation.

From your response you know I can sell you a better dish, the asking price is always subjective.

 

[moonbase]

From your response you know I can sell you a better dish, the asking price is always subjective.

There was nothing in my response to indicate that I know you can sell me a better dish.
On the contrary, I have no idea if the dish you say you can sell me is better than the one I am using. That is the reason I asked you to install the dish for testing.

The only limiting factor from my side is that it would not be appropriate for me to install a 3.7m dish or similar size.
If I could install that size I would have bought a brand new one from the Elite Antnnas stock disposal auction.

As for the price being subjective, assuming the dish is second hand and the asking price is less than retail price new then I am sure we could come to an agreement on price.
It's up to you, put the dish up for testing and you have a potential sale.

Here in eastern Germany I can receive all transponders in the upper range. In the lower area, only the horizontals come in good weather. It's raining heavily here at the moment

Of course, but in your original response it was inferred the Astra 2 downlink from a few miles up in geostationary orbit was perhaps impeding on your reception of Es'Hailsat, as opposed to far more likely sideobe pickup from the ground installation.
Under the circumstances I could sell you a dish - perhaps just a feed - that corrects that which you are currently experiencing.

The feed option sounds interesting.
Can you please let me know what feed you were thinking of providing?

Also, some info on the dish you have offered to sell such as manufacturer and size would be useful.

Yes further information of the alternative feed that has been mentioned would be very handy to know for any active system builder or experimenter as i'm having a bit of trouble with the MENA beam as well - look forward to seeing the info and pictures please.

The feeds here are optimised for PF reflectors of 0.41 and above, they would be swamped by noise from the original Precision designated focal point, unless you have built a microwave guard around the perimeter.

Install about 3" of 15GHz resistant mesh (3mm) riveted around the circumference, if you are looking to improve Ka - unlikely - then holes just under 1mm. Anything less at either band and you get reflection issues even if your feed is matched (so choose wisely with multi-band swtchers - C/Ku/Ka etc.)

I'm surprised Elite never did the design work.

 

[moonbase]

The feeds here are optimised for PF reflectors of 0.41 and above...

So are these feeds "off the shelf" from a manufacturer or customised after market?
If the need arises I can get hold of a Precision 1.8m dish that has F/D of 0.42.
It should be easy to cobble up a perimeter of resistant mesh or make up non standard feed support arms to vary the focal location of the feed.

Both @John and I are interested in these feeds so as much detail as possible would be useful including price and pictures.

Lastly, have you details on the dish you offered to sell me, make and size would be a good starting point?

Mesh, optimal Ku with 22.5mm / 27.5mm currency for comparison,

I priced some ali mesh up today to go around the perimeter of the 2.2 - about 6mtrs x 100mm wide required, come to about £100 ...... i'll give some thought for a summer project

Ordered one and arrives next week (hopefully)......yet another toy for the ever growing collection.

Be safe 'mb'
