80cm just isnt big enough for BADR4 or NSS12... official footprints say 90cm and 1.2m for poor weather margin for BADR4 . ive fitted a couple of ISS 1m dishes up here with smart tit lnb,s and they were ok even in poor weather. orbital 1m or triax td110 with decent lnb otherwise your struggling im afraid. you also have swamp over issues using a 80cm due to its beamwidth and the astra2 birds booming in next door
With my TD 88 I only get 12739H 2200 just now,and I am not sure where that is from.I think that it is a bit out after the last winds On my 100 cm dish I get.
11919 H 27500. 73%
12182 H 16200 o%
12073 H 27500 68%
TM5402HD 100 cm Dish
Edit.Out of interest here are a couple of pics of 12739H 2200.From my TD88.
They do not scan with my 100 cm Dish.
Tell a lie, a couple of nudges west on my 100 cm it comes in at 76% .
12739H 2200 that is..It looks like the Azimuth is out on that dish.
I seem to be spending most of my life sat on the shed roof farting about adjusting the dish.
I expect a comment about that from a bit farther ooop north than me.
