230 ft Multi-band Dipole

This posting provides a collection of antenna model graphs for a multi-band dipole with the following specs:

• 230 ft end-to-end horizontal
• 60 ft above ground
• 75 ft of 450-ohm balanced feeder

Model results are provided for the following bands: 160, 80, 60 and 40 m. For each band the graphs are:

• SWR at the transmitter end of the feed line
• Impedance data (R, X, |Z|, phase) at the transmitter end of the feed line
• Vertically polarized radiation pattern in the vertical plane
• Horizontally polarized radiation pattern in the horizontal plane
