Unexplained Equipment and diagram for dish network

[Edwin95]

I have unexplained equipment and diagram for three separate connected f81 connectors. Each f81 connector is connected to single receiver to single switch connected two Satellite dishes when theres three receivers. These f81 connectors are located 4 inches away from a single drilled hole when theres 3 drilled holes next to each other on the very bottom corner wall facing the side of the house located inside the house not to be confused with a wall outlet coax input. The installer got shocked after connecting these 3 f81 connectors from touching rg6 connector connected to f81. The type of floor I have is carpet but the installer didn't want to blame the carpet because the electricity came from rear of the rg6 connector screw. Can anyone tell me the equipment definition of this f81 connector installation because the installer also made sure it was grounded properly. The installer also said it's not an f81 connector nor a splice nor rg6 connector connected to this but the rg6 and f81 looked the same like the visual of mealworm and superworm. Not sure if it was an amplifier that looks like a f81 connector and rg6 connector that contains electrical material. I dont have the visual because this installation was on August 30 2002 L-o-s A-n-g-e-l-e-s came from a dish Network retailer in C-A-R-S-O-N but dissolved in 2004. There were two dish Network installers that came to my home but didn't know their names because they have to write their boss name on paperwork. However there wasn't any signal problems for 5 years! but someone can get hurt if they disconnect it which it did from a DirecTV installer replacing it with DirecTV approved rg6 cable when switched to DirecTV I had signal problems so I decided to switch to dish Network again with same wiring Equipment but safer. I need to know what type of equipment is this if anyone knows. Also what wiring diagram is this? Heres the pdf sample it is estimated based on my human eye not photos. I tried to reach dish Network they said to ask an electrician they only support on how to use the receiver.
