Introduction

The DX Engineering 2-Port Receiving Antenna Switch RLS-2 is designed to allow selection of one

of two output ports (generally connected to different receiving antennas) from one feedline.

Transfer activates with application of a +10-15 Vdc or 9-12 Vac control voltage through the

feedline.

Features

 Metal housing for superior shielding and long life

 High quality components

 Reliable F-type connectors

 Operating range from 300 kHz to 30 MHz with 75 Ω systems

 Jumper-selectable, control voltage pass-thru to the selected port

When used with two DX Engineering RBS-1 Reversible Beverage Systems, the RLS-2 will allow

selection of four directions using a single main feedline. See Figure 1. Install one or more RLS-2’s

to expand larger Beverage arrays and share the feedline back to the operating position.

The DX Engineering FVC-1 Voltage Coupler can be used to supply the control voltages through

the feedline to control 4-direction switching of a receiving antenna array or selection of four

different receive antennas.

Operation

The RLS-2 is in effect a SPDT (Single Pole, Double-Throw) RF switch that has one input port and

two output ports. With no control voltage, the NC (normally closed) ANT 1 port is connected to the

RCVR input port. With constant application of +12 Vdc or 12 Vac through the feedline ports

switch, the NC ANT 1 port opens and the NO (normally open) ANT 2 port closes, connecting to the

RCVR input port.

is blocked.

Voltage pass through is blocked (Factory Default) when the jumper is show as above. To pass

voltage through, to control other RLS-2s, the RBS-1 Reversible Beverage System, or a special

application, the internal jumper is moved to the “ON” (pin in center and right are jumpered). When

the right two pins are connected, any control voltage present on the feedline at the RCVR port will

pass through the RLS-2 to the selected port. Removing the internal jumper (or putting it on the

“OFF” position as shown above - Factory Default) blocks these voltages.

One or more RLS-2s can also be used to expand larger Beverage arrays or for placing taps along a

feedline for multiple antennas. Figures 1 and 2 depict typical configurations.
