ERI-Electronics Research 995 Series
Constant impedance ganged circulator system
The 995 Series addresses the need for additional isolation in dual input FM antennas and combining systems with its ganged FM circulator system. The ganged circulator is available to provide additional isolation for either analog or digital FM transmitters with power output levels up to 80kW. The most popular are the model 995-5, which handles up to 5kW of power, analog or digital; and the model 995-3, which handles up to 3kW of power, analog or digital, for a single FM channel. The ganged FM circulator system employs a constant impedance configuration, which provides an input match under all conditions. The system also provides broadband isolation from its output to input ports. The product is modular and can be moved and installed in component parts allowing for placement in crowded locations or sites with limited access. Mounting is floor or ceiling suspended. Frame furnished with J-Bolts facilitates ceiling installations.
