These two ERI FM antennas serve different FM stations in Milwaukee. The upper antenna is WXSS’s ERI Model SHP-4AE-HW ROTOTILLER®, which is a 4-bay, half wavelength spaced array mounted at 899-feet above ground level. The antenna below it is an ERI LYNX™ 4-bay Model DI-4A dual input FM antenna at 863-feet above ground level which is WKLH’s main antenna. The LYNX antenna has separate analog and digital HD Radio™ inputs and the antenna combines the separate FM analog and HD signals to provide a hybrid FM signal. The antennas are located on the WVTV-TV/Milwaukee PBS tower located in Milwaukee’s Estabrook Park neighborhood.
