Hi,
I have a question that pertains to setting up my Toroidal Satellite antenna, the setup positions I received indicate Elevation 45 deg, Skew 104 deg, & Azimuth (Compass Scale) 149 deg (Magnetic North) but the problems lies with the apartment building next to me. I cannot seem to get a good enough signal; the best I can manage is between 59-67 (fluctuating). I was wondering if I adjust the height would that resolve the issue?
The height is around 12-15 ft and the distance from the antenna to the apartment is around 10-12. I have had a DirecTV satellite installed at a lower position and it worked just fine but I’m wondering if this hug dish needs more clearance or an adjustment to the elevation.

Thx

It should if put in the same place as the old dish, need the same amount of clearance for the same satellite as before. However if you are trying for satellitea either side of that one then they may appear lower in the sky and need to be adjusted for. General rule of thumb is, if the obstuction is 15ft high then you need to be 30ft away from it.

Sorry I always assume northern states raher than southern ones for some reason :-doh!

Only joking L :), but it does look like Erndawg2001 is slightly further South than the norm, as he is speaking of an elevation of 45 degrees, his latitude would be helpful. :)

Well at you latitude, even at 40 degrees to the east and west of you, the elevation is still 26 degrees (about 1 in 2) but at 20 dgrees either side of you, then the elevation is around 45 degrees, so it is about 1 in 1 and a straightforward measurement. As long as the bottom of the dish clears the obstacle, then you will be fine.

Your LNB skew should only be about 13 degrees from what you say the elevation is, but these torroidal dishes are not the easiest to set up and this may be causing your signal problems.
