SWR measurements on Codan terminated HF broadband antennas.

Those antennas are mainly used by the humanitarian organisations (NGOs and UN) for their HF communications. The SWR measurement was made with the MiniVNA and vna/J software on 'reflection' mode. The antenna is connected to the miniVNA 'DUT' port with 30 meters of RG-213 coaxial cable.
The values may change depends of the antenna configuration and installation.

SWR on Codan C411 broadband terminated dipole antenna
(2 wires)

SWR on Codan C463 broadband terminated dipole antenna
(3 wires)

Having installed and tested the two models, the C463 (3wires) looks better mechanically and seams to be more efficent.
