Download the RCS-4 Manual The Ameritron RCS-4 is a remote controlled coax switch that selects one of four outputs by supplying all control voltages through the coax. The elimination of control cables gives you a fast, neat and inexpensive installation with only one coaxial line for four antennas. You get two units -- the switching box that can be tower, mast or wall mounted and the control console that is located at your operating station. The attractive indoor console has bright LED antenna selector indicators. A steel enclosure provides 100% shielding to prevent RFI and TVI. Switching time is 50ms. SO-239 connectors provide reliable connections. The weatherproof switching box uses three heavy duty 10 ampere contact relays on a rugged G-10 fiberglass circuit board. Quality components are used throughout the entire unit to ensure maximum life for the sometimes difficult-to-reach switching box. The RCS-4 operates from 120 VAC power source that allows safe operation with 14 volts control voltage. Frequencies from 1.8 through 30 MHz are covered by this excellent station accessory. Handles 1500 watts continuous.
