Guys, I think we don't understand each other. When we talk about tuner sensitivity we are talking about the signals which are on the edge of reception.
We are talking about the signals from weak satellites for example Nilesat 7W or Arabsart 26E, just to name two of them. There is countless cases of poor signals from satellites which are covering also Europe.
There are signals where one receiver can only show pixelated picture and other the normal TV pictures. And that's the difference we are talking about...
I am not interested in Astra or Hotbird, all the receivers are giving TV picture without a problem.

To get back to issue of very weak signals.
Reception of weak signals almost does not depend on the receiver behind
especially if they are in a class of receivers, of couple of hundred euro.
You should know if that is your hobby.
Reception of weak signals depends primarily
on the size and quality of the antenna
on the quality LNB
and quality cables.
The receiver is on the last place.
Why.
a better relationship between the signal and noise SNR
can only be almost exclusively achieved with the first mentioned
Antenna>>LNB>>Cables
Tuner in all of that plays a very small role
especially now that all these commercial tuners have similar characteristics.
( we not talk about professional receivers )
We should not forget the importance of filters
and method of filtering.What is more important than the tuner.
Actuall input for antenna signal is not our receiver but LNB Ghz frequencies
This signal go to the LNB from our satellite dish and not direct to antenna tuner.
This signal is converted to a lower frequency in LNB,and then goes into the receiver.
The quality of the signal is no longer possible to improve in the receiver or tuner.
Of course it is possible to get worse if you have very bad tuner .
But all modern tuners have been made so far mainly similar
and there can hardly be much improvement in relation to the signals at the border
of noise,
something is possible to achieve with filtering
but there is little difference between these receivers.
So forget ...
Which in practice means
if you have no reception on one receiver that cost
a couple of hundred euros you will not have on any for couple of hundred euros .
If you talk about the last generation of commercial enigma2 receivers.
Because their total structure is largely the same.
