Analysis of HF Monopoles - Analysis of several monopole antennas, the differences between a perfect and an imperfect ground and effects using a ground plane made of radials or counterpoises.

Two wire broadband HF dipole - This article describes the design and simulation of a two wire broadband dipole antenna for the HF band, using the software 4Nec2. The antenna is designed to operate in the full range 3-30 MHz

Rhombic antennas - Description and simulation of two types of rhombic antennas, using the software 4Nec2

Sloping Vee 470 - Article describes the design and simulation of a multiband Sloping Vee antenna for the HF band, using the software MMANA-GAL. Design with 470 ohms resistive loads. The antenna requires a 4:1 balun.
