I’m very disappointed that you have not take advice given
You purchased the signal booster that was the cheapest ok it may work for you but it’s always best to split the vm feed once
You may not fix your signal problem now but i hope you do
The zgemma h7c box has two cable tuners that need a separate feed each so how are you going to do that correctly with a 2 way signal booster ?
