Just tested out 3 new Lnb's on my 100cm Gibertini
No1 Inverto 0.2dB Black Ultra
No2 Titanium 0.1dB Mk 3
No3 Technomate 0.1dB TM-1 Super high gain
26 east Badr-4 transponder 11919 H 27500 The Inverto showed the biggest signal quality gain over the other 2 on the TM5502HD
No1 Inverto 0.2dB Signal Quality 62%
No2 Titanium 0.1dB Signal Quality 43%
No3 Technomate 0.1dB Signal Quality 35%
Other DTH satellites 28.2east,19.2east,13 east & 30 west all 3 performed very well,
Feed satellites 16 east,10 east,7 east,3 east,8 west,12.5 west,24.5 west the Inverto was by far the best,
I will do a more detailed survey with the 88 x 78 cm mesh dish next.
So far it just goes to prove what Barney said in #3 post.
