Hello All,
This weekend I set up a fixed dish dedicated to test LNBs.
It is a 1.1m dish pointed at Eutelsat 9B @ 9E. Why this satellite?
Well because:
1) I'm in the fringe area of the Italy beam - just barely can I receive it, normally it is needed over 1.5m at my location.
2) It has these 16APSK modulated signals. If we want an LNB that performs well, it has to manage this higher modulation order well ->> Means Low Phase Noise.
Tests on tranponders
12466 V and 12111V. Receiver is Edision Mio 4k, tuner1.
Need SNR to be close or above 9dB to avoid pixelation on those transponders.
Results:
1. Invacom single, Smart titatium Twin, MTI Twin all did manage to get the 16APSK transponders but always with some degree of pixelation even after tweaking.
2. Inverto Black Ultra Twin (old IDLB - the only LNB with wich I could get the 2 tranponders without pixelation (just barely).
3. Inverto Premium Twin (IDLP-TWL410) -
No signal (once in a while it showed something)
The SNR differences are very marginal in the 3 cases. But the end results are words apart.
I will not recommend the Premium when you need to lock to 16APSK signals. And I supect that for weak 8PSK signals it will also underperform when compared to the old model.
So, I am in the market for better LNB, but not from Inverto. I did not test yet the new Ultra, but my confidence in Inverto is a little shaken.
