I am setting up a multiswitch setup for a friend as a favour. I have purchased a Triax TD 78 with an Inverto Quattro Black Ultra LNB. Before I install the dish on his home I thought to try the dish and LNB at my own property.
I have a >10 year old Sky dish so I got some signal levels from it as a reference. However when it came to the 78cm dish while the dBμV levels are higher on all transponders the CNR is actually lower on some. The worst ones I tested were as follows:
Astra 2G:
11024 H - Sky LNB: 82 dBμV / 18.4 db CNR, Inverto 92 dBμV/ 13 db
11671 H - 72 dBμV/ 13.6, 88 dBμV/ 10.4
On 2E and 2F the European beams show lower CNR than the Sky LNB while UK beams have similar CNR to the Sky LNB.
Any ideas as to what the issue is here? I am a relative novice at dish installation so alignment may be at fault although I have tried specifically to aim the dish to maximise those 2G transponders and failed to even reach the Sky LNB CNR level. I am using a Satlink WS-6933 meter and am located ~ 30 KM north of Dublin in Ireland.
Thanks for any help.
