Yes I've had to put another splitter on the cable. When I scan the 
channels, I get a signal/noise ratio reported. Is this useful to me in 
this regard? Also there's some info about signal strength when tuning 
LiveTV. Are there any rules of thumb on what values I should expect or 
require there? If I'm splitting the lead from the rooftop aerial 4 times 
is there a preferred way to do this?

Thanks,
John.
