PlumbThe mast needs to be vertical. When it is not, the elevation will change as the azimuth changes. With multi satellite dishes this is crucial as the skew/tilt is affected when the mast is not plumb. If the mast is not plumbed (vertical) during setup, the elevation setting can be off. This will make it harder to find the signal. There is some misconception that having the stand’s base level will mean that the mast is plumb. This is not correct. Due to off center weight, the mast is not always at a 90° angle to the base, which allows the base to be level, but the mast not vertical. To assure that the mast is plumb the levels are placed in the mast at right angles to each other. |
