What is the difference on f81 connector between receiver and switch and rg6 cable between switch and lnb. I got shocked by rg6 that's connected to an f81 connector and receiver and my girlfriend told me if I'm okay and I said yes laughing and I regret not keeping those two connected wires because it was the funniest moment I ever had all I have left is the rg6 wire that's between lnb and switch.
