And if the window-antenna gives a good signal there, but can't deliver a 
usable signal to the other coax outputs, you could install a signal 
booster next to it, followed by a splitter if you need a local output, 
to drive the rest of your coax system.  Don't try to boost a signal that 
is already poor.
