Causes of "drop-outs"
1) Dish placement. Anything in the line of sight beyween the dish and the satellite will cause interference. Be aware that trees grow taller year by year and that a tree may not be causeing much interference in the winter but come spring when leaves sprout sap runs and the wind blows it from side to side it's effect will be greater.
2) type of cable and lenghth of cable between dish and receiver. RG 59 is too small except for a run of less than 15 feet, RG6 works much better. Signal loss is expressed as db per 100 feet at various frequencies. LNB freq's are 950MHZ to 1450MHZ if the dish seller gives you 100 feet and you need only 50 feet don't just coil up the excess outside cut it to lenght and put another connector on it.
3 Improperly installed connectors . Neatness counts spread the shield wires evenly and crimp the ring nicely

Good information. However, RG-59 swept to the satellite band of frequencies exhibits a loss of 3 db per 100 feet (half power). RG-6 swept at the satellite band exhibits 3 db loss per 150 feet. Not much difference.
A point to deliver, also, is that there have been numerous complaints from cell phone users about poor reception. This year there have been a large number of solar flares from the sun which is hampering communications. This also is affecting satellite reception.
