The Model 425 FM Isolation Transformer is finished with tuning and test, and it’s way to shipping. This type of transformer allows the transmission line feeding an FM antenna to pass the transmitter power across the base insulator of a series fed AM tower. The Model 425 is rated to handle up to 25 kW of FM power and up to 40 kV Peak AM Voltage while adding very little additional AM Shunt Capacitance.
The radomed elements are part of a new 12-bay SHPX Series diplexed FM antenna built for an FM station in northern Iowa. The interbay lines in their crates, and now the last of the elements are staged for packing.
The two towers pictured are 328-foot self-supporting towers owned by American Tower on West Tiger Mountain east of Seattle, Washington. The towers were manufactured and erected by ERI in 1999. The tower on the left includes a T-Bar that supports two UHF television antennas. The tower on the right now supports a new ERI LAMBDA® Optimized FM Mounting System that is 135-feet tall. The FM antenna is a 16-Bay AXIOM® Master FM Antenna that is fed by two 6-1/8-inch, 50-ohm, rigid transmission lines. The antenna is the primary FM antenna for six Seattle FM stations.

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.
This is an 8-Bay AXIOM® Master FM Antenna just completing final test and almost ready to be taken down, get painted and packed for shipment. The system supplied by ERI also includes a three station FM channel combiner.
