How to receive 4,2 sats with diseqc 1.0

[Satphoenix]

Only a hint for users with 4 sats on a dish with diseqc-switch:

I have a 90cm dish with 4 lnbs on 4,8°, 13°, 19,2° 28,2° east and all with good signals.
I started a scan at 4,8° and what should I say - suddenly I received "BBC Persian" on that position. But BBC Persian is on 7° east.
Eutelsat 7A has strong signals so that it's possible to receive some transponders (not all) from there even on 4,8°.

These are: 10721h, 11221h and 11456v (the other transponders don't work)

Surprising, but it really works if you have the 4,8°-lnb at the edge of your dish. So you can receive 4 + (~0,2) sats...

I have never heard about lnb with range so wide(2,2 degree).
BBC Persian is at 13E as well so maybe your diseq doesn't work properly.

It's not the lnb, it's the fact that in the edge of a dish you don't have a focused point. It's an ellipse which (in that case) covers up the focused point of the external lnb.

What for brand is that dish you use?

What for brand is that dish you use?

It's a dish from "triax".

90 cm

And it's 13 years old, but it's working correct.

The center of the dish you is focused on what satellite? You have good signal in 28,2° east?

Re: How to receive 4,2 sats with diseqc 1.0

I've focused ~16°. I can say only ~ because there's no lnb in the dish focus like as only one lnb in the center. Near the center is 13° and 19,2°. And in the edges were 4,8° and 28,2°. All 4 (main) sats have a good snr: 13° and 19° about 80% and the other two have 75%. Enough for clear signal.
The 7° signal has only 45% - 55%. Also enough for good signal. OK, in rain they disappear sometimes.
It's only a hint for users of 4,8° (and not in dish-focus!).

Ohh, I see, posted in wrong section, sorry! Threat is moved to the correct place.

2,2 degrees is a very wide range for receiving signal from one lnb.
It's imposible.
I remember that one time I had signal from a satellite near to another but it was only 0.5 degrees.
You should better check your settings of your box, because you may have mixed up the settings for diseq switch.

In the center of of a dish you're right, in a corner of a dish you're wrong and it's possible.



It's because when you're wide outside the center, you don't have a focus point for the signals, you have a "focus area" but therefore the signal looses it's strength. And this "focus area" of 7° overlaps a bit in the position of the 4,8° lnb.
And there's a second condition for getting a signal:
Sirius on 4,8° doesn't use lower frequences - in that case 10721h, 11221h and 11456v. Otherwise it won't work and you receive nothing or even the main signals are getting disturbed.

Well it's a strange story I give you that, but I believe you.
I use a multifocal dish and I can only receive good signals when correct pointed to the desired sat, but in your case there must be a glitch in the build of your dish wich lead the signal from 7° to your 4.8° pointed LNB.
If you play a little with the LNB and point it more to the 7° sat you be able to get better signal from it but at the same time sacrifice signal from 4.8° but there must be a way in the middle

I can confirm that you can catch two satellites, on one lnb on range 2-2,2 degrees, when i tune Badr on 26E (motorized dish)I'm receiving few transponders from 28,2E, also I'm getting on 4.8E few signals from 3E (multifeed) edge position.

...point it more to the 7° sat you be able to get better signal from it but at the same time sacrifice signal from 4.8° but there must be a way in the middle

I pointed it defenitifly to 4,8°. The (much lower) signals from 7° are a little extra gift from that position. And there work only the three named transponders.
That's why i call it 4,2 satellits.
But you're right, if I move a bit more to 5° or even 5,5°, 4,8° will get lower and 7° will increase.
