Figure 2: RLS-2 Configured to Switch 4 Antennas
Notes:

Uses single coax run from each RLS-2

Uses voltage on the feedline to switch the RLS-2 s

RLS-2M is a converted RLS-2 that switches when −12 Vdc is applied to feedline, other
RLS-2 s switch normally, giving port selection per table below
Voltage Applied
to Feedline
Selected Port
0 Vdc Ant Array 1, Segment A
+12 Vdc Ant Array 1, Segment B
-12 Vdc Ant Array 2, Segment C
12 Vac Ant Array 2, Segment D

The FVC-1 applies the voltages to the feedline and can be controlled using BCD logic
with the CC-8A or a switch closure to ground arrangement
The configuration shown in
Figure 2 requires a modification to one of the DXE-RLS-2 units to
operate at -12 Vdc to allow the switching functions shown above. The modification consists of
removing one diode and installing it backwards as shown below.
