Introduction
The 2 x 8 Remote Antenna Smart Two Radio Switch System DXE-RRMX2X8 uses a DXE-
RR2X8 remote switch, DXE-MX2X8 interface unit and two DXE-CC-8A control consoles.
The two DXE-CC-8A control consoles supply the BCD switching signals to the DXE-MX2X8
interface unit which then sends the appropriate signals to the DXE-RR2X8 remote switch to select
one of the eight output ports for each DXE-CC-8A control console.
The dual star arrangement of 24 internal relays provide greatly improved power handling, port-to-
port isolation and SWR over conventional switches and allow connection of the eight antenna
output ports to either the master or slave input ports.
The system offers virtually no loss at HF and excellent low-loss performance (less than 0.16 dB
loss) on six meters.
Each control console (A and B) can select one of 7 or 8 positions available. When one operator has
a particular position selected, the other operator is locked out of that position - first come, first
served.
Features
Enclosed relays provide exceptional performance and are moisture resistant. The DXE - RRMX2X8
system can be used to simultaneously select multiple output ports as well as conventional one-of-
eight antenna switching. This allows the
DXE - RR2X8B to be used in complex antenna systems as
well as traditional switching arrangements. Ports that are not selected are grounded.
The DXE - RRMX2X8 system also uses removable screw terminal plugs for the control cables. The
removable plugs greatly simplify installation by eliminating the need for soldering. Disassembly is
not required for control wiring access.
The DXE - RRMX2X8B also offers the following features:

RF Shielded Weatherproof Housings - unique protection

Excellent Port-to-Port Isolation; greater than 70 dB at 30 MHz, worst case.

Ports not selected are grounded

High-RF tolerant UHF connectors

Enclosed 16 ampere RF relays

Safe 12 volt DC relay operation

MOVs for surge protection on control lines

RF bypass capacitors

Includes two DXE-SSVC-2P Stainless Steel
V-Clamps for mounting

The DXE-MX2X8 interface unit interfaces
between the DXE-RR2X8 and the two DXE-CC-8A control consoles for seamless
operation

The two DXE-CC-8A control consoles have LED indicators and provide the BCD
outputs to the DXE-MX2X8 interface unit
