Thanks again Electron.
I just installed the coupler and my signal strength went to a constant 7 out of 10.
I rescanned my stations and im now getting 16 stations which include Fox and channel 7.
I also picked up another 4 way splitter. It doesnt say what the Insertion Loss is other than "Low Insertion Loss" on the back of the package.
Ideal 4-Way Splitter
I havent put it in yet, as the other rooms that the splitter fed aren't used.
Ill try bringing one of the tube TV's we have laying around upstairs and connect the antenna directly to it and see what it does.
