Review: Great - Great Review: Quality Product - Quality transformers! I recommend switching out the typical thin wired transformers that come with your indoor/outdoor antenna with this one. The copper is the same gauge as RG 6 coax, better in corrosive conditions. I wish I can say that I've been able to compare and contrast with these transformers in an exact antenna location, i.e. swapping out old with this new item, but I haven't. What I can say is that with a "clear" direct line of site, approximately 40-50 miles from the Antenna Stations, I get 70 channels, which is damn near max of available over the air channels in our area. ## Features - Connect your outdoor or indoor rabbit ear type antenna to TV with coaxial type input. - Use to connect older TVs with flat cable input to coaxial cable.
