I have DISH. I run the coax from the Trailblazer antenna through the window above the sink and up to the top cabinet where my DISH Hopper receiver lives. The output from the Hopper goes to the HDMI connector in the cabinet. There is a plug for power on the top shelf also.
One can not run the Trailblazer antenna through the coach coax and have it distributed to all the TVs. First the antenna communicates with the receiver and there is voltage on the coax line. [NOTE some people have shown a mod to allow this to work]. Since I only watch TV in the main cabin, this is not an issue. Second, the output of the Hopper is HDMI.
