The design parameters for such an antenna are based on /2 at 3.6 MHz and fed with 100 feet of nominal 450Ω (actual Zo around 400 Ω) “ window” transmission line. The resulting SWR curve is shown in Fig 12-13. The resulting line losses are shown in Ta-ble 12-2. The dipole length in feet is found by dividing 468 by 3.6, resulting in 130 feet. I will assume a height of 50 feet, reasonable for many locations with mature trees.
