Coaxial cable ground blocks are used to ensure a proper ground path between a coaxial drop cable and a ground wire. This ground block does just that with four cables. It is a zinc anti-corrosive standard ground block that accommodates a 12 AWG ground wire with ease for grounding your HDTV antenna or cable TV installation at home or the office. This is what you want to use to ground your cable TV or HDTV antenna coaxial cable outside before bringing the signal inside. This way, lightning strikes and power surges have an opportunity to arrest before reaching your TV and entertainment electronics. The grounding block will convey this unwanted electrical energy to a ground rod via a copper ground wire that you install (not included). The Holland GRB-1 Single Coaxial Cable Ground Block is a high quality grounding/bonding block designed to help protect audio and video equipment from lightning damage. Show more
