The original dipole
NEC2 3-dimensional pattern for the KK1D Dipole on 17 meters. Everything "warmer" than green is more gain than a single band dipole, everything blue is less gain than a single band dipole.
The main (and currently only) HF antenna at my location is a 140 foot (42 meter) dipole at a height of 10 meters fed with ladder line. The antenna is oriented North-South to within an error of 5 degrees or so. It works out pretty well, it has more gain than a dipole towards Europe and some other DX locations.
I found it handy to work up the antenna patterns in Arie Voors' 4nec2, then plot them "sandwiched" with an azimuthal equidistant chart centered on the QTH. Gabriel Rivat's (F6DQM) AziWorld software is used to create the maps, and the GIMP is used to sandwich the NEC2 and Aziworld images.
The patterns on 160 and 80 meters are essentially omnidirectional and very high angle.
The principal antenna tuner is a LDG AT-100ProII autotuner, with a Dentron MT-3000A for backup. At least at this QTH, the LDG does fine on all bands except 160m. The Dentron does fine on all bands except 10m.
