Diversity Fin Polarization AntennaThe patented Diversity Fin is a multi purpose antenna for wireless microphones that reduces dropouts using a cross polarized, hybrid design. It combines one LPDA and one dipole antenna in an orthogonal (right angle) configuration. One element captures vertically polarized waves, and the other horizontally polarized wavesdoing the same job as two "shark fin" paddles while greatly improving RF and audio performance. To use, just connect both the A and B
