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-2
s, 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-2
s 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.
