I was hoping someone would have a suggestion of what type of signal amplifier I need. My home has a OPEN HOUSE cabniet where all my coaxles come together the problem I am having is by the time you run the TV2 out 21-69 to the cabniet and try to get the signal to another room the run is over 150 feet and I can not get the signal to the room. Will a signal amplifier coming off the reciever work and if so what one would you reccommend???
