George gets noticeably more rain than Mossel Bay, and it falls across the year, often as soft drizzle from cloud that sits against the Outeniquas. Dense, wet cloud weakens the satellite signal. A dish aligned by eye, or one that has been knocked slightly, loses its picture in this weather long before a well-set dish does. That is why we align every install with a meter and record the reading.
Moisture is the other problem. Twist-on connectors and taped joints let water in, and the copper inside the cable turns black over a few winters. When we repair a George install we usually replace the outdoor connectors with sealed compression fittings and cut out any cable that has water in it.
Plots in the older suburbs are big and green, and pines, oaks and wild figs block more dishes here than anywhere else we work. The dish faces north-east, so trees on that side of the house matter most. On the estates east of town it is the opposite: few trees, but rules about where the dish can be seen from the street.
