Ladder Line Dipole/ZS6BKW/G5RV Center Insulator
Product Details
Simple 2 piece ladder line to wire and center support for 450 ohm ladder line spacing. Molded insert to fit between ladder line cutouts. Used on Palomar ZS6BKW antennas.
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.
