Background of inventing the new satellite parts - DUP150
According to the National Severe Storm Laboratory, lightning is the most dangerous and frequently-encountered weather hazard that most people experience each year. In an average year over 100 people are killed by lightning in the United States. This is far more than are typically killed by the more high-profile natural disasters like tornadoes and hurricanes. Lightning is also responsible for up to $1 billion in property damage each year, which certainly includes thousands of home satellite tv equipment being taken off the air. An effective lightning protection method for satellite tv equipment is needed, then the novel satellite parts for satellite tv equipment lightning protection - DUP150 was invented.
How does the novel satellite parts - DUP150 works?
DUP150 automatic switch is used for satellite tv equipment lightning protection. It's connected on the cable between the satellite dish antenna and the satellite receiver. DUP150 plugs the dish into the receiver automatically when the receiver is powered on, or unplugs the dish from the receiver automatically when the receiver is powered off or turned into sleep mode. When unplugged, the air gap between the dish side parts and receiver side parts is long, it is 150mm typically. The endurance voltage for lightning surge of this air gap is up to 150kV. This air gap can block the lightning overvoltage and prevent the satellite tv receiver and tv equipments connected on the receiver from being struck by lightning. If DUP150 is installed at the place just after the cable pass through the wall into the house, it can prevent lightning from entering house through the satellite dish cable.
What's the effect of the novel satellite parts - DUP150?
According to the A.C. Nielsen Co., the average American watches about 4 hours of TV each day, so the their satellite receiver is power off or in sleep mode about 20 hours each day. If the novel satellite parts - DUP150 automatic lightning protection switch is used, it disconnected the dish cable from the satellite receiver and keep a 150mm air gap about 20 hours each day. This reduces the probability of being struck by lightning about 83% (which is 20/24) comparing with the condition without installing the novel satellite parts - DUP150. Normally the lightning storm weather always comes with some indications, in the other 4 hours watching time, though the novel satellite parts - DUP150 is turned on, we can remote-control the satellite receiver into sleep mode when those indications happen, then the novel satellite parts - DUP150 is turned off, then the satellite receiver and other tv equipments connected on the receiver are safe. We needn't to unplug the satellite dish from the receiver by hands in the lightning weather; this keeps our body safe further more.
Comparing the surge protective devices and grounding methods, using the novel satellite parts - DUP150 is the most effective way to prevent our indoor satellite tv equipment even our body from hurting by lightning in a lightning weather. Its operations are observable through the transparent window, this can reassure the user.
