It's dimensions match the perimeter of the Commons very closely. Several features of this antenna make it a good selection. It can easily be loaded up on other bands. It is somewhat deaf to electromagnetic noise. It's size makes it a good listener to low angle signals - like a Beverage antenna.
Magnetic radiators are relatively unhampered by ground loss - a nemesis for work on the low bands.
Early tests showed the antenna to outperform our most optimistic predictions. Here, Yuttana and Sue N8MMH position one of the corner supports. Each of the corner tripods is grounded, electrically. These measures greatly reduce the risk of damage from electrical surges. Charge is dissipated to the atmosphere rather than building up, as it does on the surface of a VandeGraff.
