Seems like you have a poor/week signal coming from the RF input.  The 
fact that splitting it makes it worse almost proves it beyond a doubt, a 
booster might help.  Where is the signal coming form?  An antenna, 
cable?  The booster should be placed as close to the origination point 
of the signal as possible.
