Title: Does not combine signal very well
Review: I purchased this product with hopes of combining my antenna signal with my analog cable box in order to get local HD channels on a secondary TV without having pay my cable company for another HD box. When I installed the combiner I immediately noticed a degraded signal especially from the cable box. The picture from the cable box signal was especially snowy. I tried several fixes to clean the signal but nothing worked. I removed the combiner and installed a switch and the signal from both sources is much cleaner (no snow) -but now I have to get up, walk over to the TV and slide the switch when I want to change from local HD channels to the cable box channels. I did not evaluate the splitting function of this device.
Is this product review negative?
