hi everyone, ineed some help on a dish installation.

im trying to find hipasat 30w, im pretty sure i have found it but the problem is my signal quality is falling and rising very quickly, its as if there is something in front of the signal could this be the cause, because there is a tree 9 metres from were my sattelite is located , the tree is about 9 metres tall. Or could it be that i have installed the dish very low, i have put it just above my kitchen window. could someone please help me on this problem

My Satellite Setup
Technomate 5402 HD M2 Ci, DM7000s, Transparent 80cm Dish, Moteck SG2100 DiseqC motor, lots of legacy gear. Meters: Satlook Digital NIT, Promax HD Ranger+ spectrum analyser.

Could be the tree, could be the LNB skew, as you are looking at the dish from behind the LNB, the bottom of it should be at around 5 O'clock.

The elevation for that satellite is around 1 in 2, so to clear a 9m object, you need to be close to 18 metres away.
