Instituting a monitoring package for power supplies and amplifiers using the return network will help in spotting problems with power supply voltage fluctuations, battery condition, signal levels and amplifier conditions. The cost of a monitoring package is quickly offset by the ability to spot problems before they occur. Because dishes really are the lifeblood of a cable system, make sure you ve devoted the time to carefully inspect each part. In addition to inspecting cables for damage caused by abrasion, rodents or the elements, two additional inspection points are to check for cracked cable jacket, permitting water damage to the cable and connector, and corroded connectors, which should be replaced. Cracked jackets will allow water to quickly attenuate the signal or short out conductors.
Corroded connectors can cause intermittents and signal attenuation.
Although a weep hole can be drilled in an emergency to drain water from an air dielectric line, it s not standard operating practice and must be repaired later. Use a rubber squeegee or broom to pull snow out of the dish. I ve seen techs use the rubber mallet and end up with a dish as seen in the top photo on page 108 not pretty. As your technicians drive around their service areas, they should watch out for open or unlocked pedestals and power supply doors, broken lashing wire, too much sag on cable spans or drops that are too low, and tree limbs that overhang or rub against cables. Training your field staff to look for potential problems helps avert emergencies later.
