Linked dipole designer

Design a linked dipole, in inverted-Vee format, tuned for up to six amateur HF bands. This antenna is easy to build and to erect, needs just a single central support, and bands can be quickly changed by opening or closing links between the elements in the antenna.  Read more...

Antenna performance

Here you can generate plots of propagation patterns, VSWR chart, antenna currents and Smith charts for your antenna over a choice of ground types. By changing the physical dimensions of the antenna, and refreshing these plots, you can learn a lot about how your antenna will perform in the field.
