1. Antenna design and simulation.

Codan C463 MMANA-GAL model — **Fig. 1.** MMANA-GAL model of the Codan C463 antenna.

The C463 is a three-wire broadband dipole suitable for automatic link establishment (ALE). It incorporates a balun and loading elements whose electrical characteristics are not publicly specified by the manufacturer. It can be installed horizontally, favouring longer-distance (DX) communication, or in an inverted-V configuration, favouring near-vertical incidence skywave (NVIS) propagation.

2. Simulated radiation patterns.

This section presents radiation patterns simulated with MMANA-GAL at selected frequencies.

Codan C463 radiation patterns from 2 to 10 MHz — **Fig. 2.** Simulated radiation patterns at 2, 4, 6, 8 and 10 MHz.

Codan C463 radiation patterns from 11 to 20 MHz — **Fig. 3.** Simulated radiation patterns at 11, 13.25, 15.5, 17.75 and 20 MHz.

At frequencies up to 10 MHz, the simulated radiation patterns are approximately omnidirectional in azimuth and favour NVIS propagation. The maximum simulated gain in this frequency range is approximately 7.5 dBi. Above 10 MHz, the radiation patterns become more irregular and vary significantly with frequency. For this reason, a horizontal installation may be preferable for longer-distance (DX) communication.
