10 M (75-ohm) | $55 | $90 |

Why two lengths? 3/4-wave are typically used with 2 and 4-element HF quads, while 1/4-wave are long enough for a 3L, where the driven element is closer to the mast. Read more at Feeding a Quad.
Cables are constructed using high quality coaxial cable and terminated with silver-plated/PTFE connectors.
Fully terminated, weatherproof and ready to install.
