Okay, I picked this up locally as I allready have an identical dish, approx. 80cm. (BBC dropout in heavy rain in Rogaland, Norway)
The new one is 1m.
Unfortunately, the owner had replaced the funnel and original LNB with an universal LNB... Sounds cracy, but he said it worked perfectly. He installed it with a bracket made of wood... poorly made and rotten so I discarded it.
My question is now:
1)
Where is the exact location of the universal LNB? At the drawings it shows the focal line is not paralell to the aluminium beam holding the sub reflector. So the universal LNB should be tilted a bit accoding to the line on the drawing...
I am not sure of the distance either, the previous owner simply but the universal LNB by the screw hole for the original LNB bracket (!)
As mentioned I allready have a working dish, where I spliced in a universal LNB in line with the big funnel after the magnetic polarisator (not used).
Se other post for that picture.
I guess I could align the satellite dish, then fine tune the LNB on a strong sattelite, like hotbird to find the sweet spot of the LNB.
Another solution is to look for similar antenna and get hold of the missing funnel... maybe som small antennas for sale, I assume they only changed the main reflector for the different models.
It's gonna be a challenge to make a bracket of aluminium, but I have plenty of aluminum profiles.
2)
I have an old canal digital LNB, but it has 3 outputs. One output mentions 4 frequencies, while the two others are for some other service (?) Will get a picture later. Anyone know what kind of LNB is? Can it be used as an universal LNB by just using the one plug?
The new one is 1m.
