Reception on 80Cm dish
Why do I get such a spread between both measurements
How can I improve the balance?

 

[Manikm909]

r u sure you're on 16e ?

 

[rodscha]

yes of course,albania on 16E 12639 H 10833
Their signal behaves very differently from that of Croatia,Slovenia,Romania and other "adria" ones

[Channel Hopper]

The far lower symbol rate (and perhaps the FEC of 3/5 ) will have something to do with differing reception characteristics.

Could be cordless phone interference?

 

[rodscha]

no we aven t got any... and ONLY albania shows this

 

[rodscha]

also,the LNB skew to optimise albania is higher than the Slo/Cro/Romanuia bunch,which,in turn,demand the same skew

so,higher symbol rates?

 

[astra19]

It’s on the weaker side for me, probably the weakest out of all on 16e. How is your signal on Credo TV? That’s a little stronger for me but not by much.

 

[rodscha]

my point is,why do I get 90% in strenth (red line) and 10-15% (green line)
the pic breaks out at the slightest cloud in the sky... better in the morning,vanishes in the evening

 

[rodscha]

and if I optimise Slo/Cro/Rom at "a certain skew" I won t get albania at all
ocnversely ptimising Albania will wipe offSlo/Cro/Romania
hence my belief the albanian mux to be on a different sat

 

[Channel Hopper]

Rule of thumb, skew is not always 90 degrees so peak on minimum signal.

You are at the mercy of the Universal LNB design.

 

[ozumo]

Perhaps the horizontal and vertical probes in the LNB aren't perfectly perpendicular?

 

[rodscha]

I did that,peaking on Albania
But then Slo/Cro/rom do not show....

 

[ozumo]

Have you tried a different LNB?

 

[LeBelge]

With my Availink tuner I have this

 

[rodscha]

so ,in Belgium you get that much of a signal
What size dish have you got?

 

[scopus]

All OK in the Midlands UK on a 1.3 dish

On a wavefrontier T90 in Belgium, I get:
12639H: 9dB FEC 3/5
12643V: 10.1dB FEC 2/3
11636V: 11.9dB FEC 2/3

So slightly weaker signal indeed on 12639H and because of the more critical FEC 3/5 a higher SNR is needed
for correct reception. 9dB is enough here in Belgium (5.5dB would be the absolute minimum needed)

On smaller dishes there could also be some influence from neighboring satellites (19.2 E 12633H)
especially if the dish would be misaligned. A problem with the skew could also explain it.
Below is a spectrum showing the overlap on a correcly skewed lnb. Note that the indicated frequencies and synbolrates
are not the true ones, but the ones which are good candidates to start a blindscan.
