This is how to match the popular 75 ohm CATV hardline to a 50 ohm antenna:
         |                                                  |
         |        Overall Length 0.1628 (wavelength)        |
         |<------------------------------------------------>|
         |                                                  |
         |     75 ohm coax                50 ohm coax       |
         |     e.g. RG11/U                e.g. RG213/U      |
50 ohm----|{{{{{{{{{{{{{{{{{{{{{{----}}}}}}}}}}}}}}}}}}}}}}}}|----- 75 ohm

          |                    | |  |                      |          line
