To avoid Dstv satellite dish no signal problem, you’ll have to find out the proper direction to point your dish. You should try using compass and inclinometer while aligning your satellite dish.
To correctly point your DStv satellite dish, you will need to find out the azimut, elevation and LNB polarization/skew values.
Azimuth in satellite dish is the dish position in respect to north. It is the rotation of the entire antenna around an upright axis. It is the side to side angle and is mesaured in degrees.
Elevation on satellite dish means the angle between the beam pointing direction, directly towards the satellite, and the horizontal plane. It is simply the up-down angle. When your dish is pointed almost straight up the elevation angle is nearly 90 degrees. Satgist
