The C172-1-1 Dual-Mode Batwing antenna is an extremely lightweight,Mach 0.88 capable antenna, providing two individual antennas for complete hemispheric coverage. The low-angle mode provides quarter wavelength monopole performance for the elevation sector of 0 to 40 degrees, while the upper mode crossed dipole provides coverage from zenith to 40 degrees elevation.
External 0 – 90 degree couplers such as our H26-1 and H29-2-1 are required to develop the upper mode circular polarization and are connected as indicated below.
