Note
The RCS-10 is a versatile antenna switch designed for 50-ohm systems. It handles high power, and sealed relays offer excellent life and connection reliability. It requires only three small isolated control wires, plus a ground return that can even be the coaxial cable shield. The relay box can be mounted indoors or outdoors.
The RCS-10 Remote Antenna Switch selects one-of-eight “antenna” connectors or “ports”, and connects those ports directly to a single common port for a feedline.
The RCS-10 will work well in nearly any system requiring switching of unbalanced or coaxial lines, especially those requiring good quality 50 ohm RF switches.
The RCS-10 is a remote controlled switch using relay contacts. The control head can be conveniently located and only requires use of small low-voltage low-current telephone-type fourconductor control cable. Any switch port can be used as either an input or output, so you
can select one-of-eight radios to one feedline or one-of-eight antennas to a radio.
The RCS-10 uses low voltage and low current, and can use inexpensive and easy-to-route control cables. Bulky and expensive coaxial and control cables are not required, and wiring is very simple. Since all cables route through one common point that can be grounded, lightning protection is almost always significantly better than conventional wiring methods using multiple coaxial lines into the operating position.
The RCS-10 Relay Unit reliably handles power levels of 5,000 watts below 30MHz, and power levels of 2.5kW at 50MHz. Port-to-port isolation is typically in the 40dB range, but varies with frequency and the ports being used. Loss is very low, and this switch can be considered lossless below 30MHz.
The RCS-10 Relay Unit can be used with any BCD (binary coded decimal) 12-16 volt dc 400mA control system. The relay box is available with or with out lightning protection. The RCS-10L uses the same RCS-10 control box. The relay box is labeled RCS-10L for lightning protection. Each antenna port is protected.
