- Bobtails are vertical arrays that look like the letter "E" turned 90° clockwise onto its tails. They have 3 quarter wave vertical elements and are one wavelength long. The Half Square is a shortened Bobtail- it has 2 quarter wave vertical elements and is a half wave long.
The Sloping Vertical Dipole
- The radiating part is the vertical half of the dipole. You get nearly radiation in all directions, the second half must not be in 180°. The table below show how we get an impedance for direct feeding of 50Ohm coax. by DK7ZB
- This article describes the characteristics of an horizontal dipole and shows the results of several simulations made with MMANA-GAL, covering models for the 20 m, 40 m and 80 m bands.

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
