PBD 4 Way HD Digital 1Ghz High Performance Coax Cable Splitter

Internal circuit board for better reliability/durability.
coaxial cable splitter splits an incoming coaxial signal from cable television (CATV), VCR, satellite receiver, cable box, or antenna into multiple outgoing signals.
Low signal loss of 3.5db on each output port improving performance and speeds.
