Hi.

I agree. And you can see what channels that are on which transponder on Lyngsat.

Lyngsat has a page with this heading

"Lyngsat Sky Italia on Eutelsat Hot Bird 13B/13C/13D at 13.0°E"

If you google it without the " " will I expect you find it.

Here can you see which transponder that has your favorite channels and is important for you.

Regards carsten.

I'll try to explain. In this moment here is good weather. Sky is clear and it's sunny. The configuration it's like the one of yesterday. Here the signals: on hotbird, my favorite channels: 12341 75%, 11994 85%, 11410 92%. On 23.5: overall 85%. On 28: BBC 90%, sky uk 12011 71%. On 19.2: 11331 90%, 11914 95%. So these are the signal I get in good weather conditions. You see that there's much differences between frequencies.

Hi Eliosfederico.

That is normal. The difference can be to different reasons, Tranmitted from different satellites ( Hot Bird 13B/13C/13D ),
Transmitted from a Vertical or Horisontal transponder, Be on a different beam, some beams are aimed for Italy others for Europe.

The importent thing for you is to have the minimum requered signal on all the transponders that you want to see, even in rain. Plus a little extra.

The value are different on the different SAT Receivers. Do you know the value for yours, when you loose the signal?

Regards Carsten.

On HD channels the minimum required is around 55%. For SD channel I saw it going down up to 40 without problems. But I never watch SD channels so I would say with rain it shouldn't go under 60%.

well they don't look to bad im only getting 2-8% on sats I tried but its raining here lol

What options do you have try a bigger dish? make a lnb shield to test. We all have the same problem too but snow is worse for me and dish to high to sweep it off.

Make a shield for lnb and see if it helps

I just tried with a single lnb.
19.2: Sky DE 98%, 13.0: 12341V 78% (before 75%), 11354V 90% (before 80%), 23.5: 11858V 91% (before 81%), 28.2: BBC 100%. (before 90%). So I can conclude that without the rail I get an overall improvement of 10%. Ok so now how I make it better with the rail?

Hi.

When you look at the LNB as a single or look at the LNB on the Rail. What is the difference. Is it higher?
Is it pointing more upwards?
Is the distance to the dish different?
I am sure you can see some difference, or may be you can take some picture of both and show us. But we will then need picture taken from the same spot and with some commen references, may be the boom ( arm ). It is not the picture that is important. The important thing is if you can se any differences.

Carsten.

Put the single lnb in the middle of the rail and try again and see what differences you have, I have read that you can turn the bar over and it gives you better adjustments.

You might find you will get better results with a Inverto Black Ultra lnb

Hi.

I am not sure any more. I had previus in this thread mentioned the Inverto Black Ultra lnb, but it then must be the Single or Quad. The Twin has a design flaw.
What the High Gain or High Output LNB is god at is if the sinal from ALL the transponders on a SAT is weak. Then it in some cases can improve the signal with its higher gain.

But here has many of the others transponder higher gain than the transponder with his favorite channels. I am afraid that the input circuit in the LNB here will reduce the gain for all the transponders to keep the stronger from getting a to high output. And then there will be no improvement to his favorite transponder.
The LNB will receive from more than one transponder at the same time and adjust acordingly.

Carsten.

Well I think that at this point I should leave everything like this. Anyway on my favorite channel on 13E the loss of signal on the rail it's just 3% (from 78 to 75) and not relevant. The only one that I'm a bit sad about it's the 23.5 on the rail there is 8% loss (from 91 to 82). I actually don't think that lnb would help. But I saw it in a local store for 15 euros.

I ordered two new full size LNBs. One is the same brand as the rocket ones I have now installed. You can find all the details here: http://www.megasat.tv/en/home-tv/lnbs/megasat-twin-lnb-high-gain
It has a 70dB high gain and should be less sensible to the raindrops that stay on it. (The rocket LNBs I have now they have 60dB gain). I also ordered this one: http://www.inverto.tv/products/product.php?section=1&id=86&cat=4 It's the Inverto Black Ultra quad which should have a 60dB gain, just like the rocket LNBs I have now (weird?!). I should receive them tomorrow and I would test wich gives me the best signal.

Looks like your not giving up just yet lol Its all about learning mate. There is many posts about the Inverto Black Ultra being better but there is nothing to say your lnb aren't fine anyway.

I have seen a few move the centre bolt away and refit it further down the rail allowing to 5/6 lnbs but supporting the rail with wire.

Is there no option for a bigger dish??

Before I had a Technisat Multytenne and was a 45 cm dish and that for me was already the maximum (in the garden). But with just cloudy weather there was no signal so I went to my local sat store told them which sats I wanted to receive and they said that a 79cm was good for it. So, no, I can't put a bigger one.

About the rail and the wire I didn't get it. What you meant?

Hi.

I am sorry but the BLACK Ultra is a Quattro and not a QUAD.
A Quattro need to be connected to a Multi-Switch. What you need is a QUAD, that is equal to your TWINs but just with 4 outputs.

You're right. I'll change the order! But why can't I buy the twin? What's wrong with it?

Okay, now I see the difference. I'll try to change the order but the quad is more expensive than the quattro :( You talked about design flaw about the twin. Can you explain better? What's wrong with it? I didn't find anything online about this problem.
