The best way to convert a high-definition signal like HDMI into coax is to use an HDMI-Over-Coaxial converter. These will typically be able to convert the HDMI signal so that it can be transmitted over coaxial cable or vice versa.The cable is a transmission line (read more here) and it will transport a signal properly ONLY when the input and output of the cable/transmission line is TERMINATED by the proper impedance ! So a 50 ohm coax cable needs a source with a 50 ohm output impedance and it needs a 50 ohm load at the other end of the cable.Expanding Equation 7.3.1 to show explicitly the dependence on conductivity, we find: R ′ ≈ 1 2π√2 / ωμ0 [ 1 a√σic + 1 b√σoc] At this point it is convenient to identify two particular cases for the design of the cable.
