RG-8X male to male antenna cable for ham radio, CB and Short wave listening (SWL). This cable is 50 ohm and 50 feet long double shielded with foil and braid with PL-259 connectors on each end. All the connections inside are soldered and the cable is made of copper conductors with coax having PVC jacket. RG-8X is generally good up to 1500 watts PEP at HF frequencies below 30 MHz.
50 ohm coax to 75 ohm balanced output baluns are useful for low (< 1 wavelength) dipoles exhibiting 75 ohm characteristic impedance or for matching to balanced ladder line whose endpoint impedance is near 75 ohms.
50 ohm coax to 75 ohm CATV coax connections are easily done with a 1.5:1 unun with SO-239 connectors on input and output. Likewise 50 ohm coax to unbalanced verticals or loads near 75 ohms can be matched with a 1.5:1 unun.
