Additional System Configurations
Diagram 3
shows a new receiving application. The
DXE-RTR-1A
Receive Antenna Interface for
Transceivers now allows owners of transceivers which lack a receive antenna input to use a phased
receive antenna array. This diagram shows the connections for use of the
DXE-AAPS3-1P
Electronically Rotatable Receive Antenna System, which consists of two
DXE-ARAV3-1P
Active
Vertical Receive Antennas with Internal Antenna Disconnect Relays and the
DXE-NCC-1
Receive
Antenna Variable Phasing Controller using the
DXE-RTR-1A
Receive Transmit Relay.
Diagram 4
details the connections to optional equipment required when operating high power and
using the
DXE-AAPS3-1P
Electronically Rotatable Receive Antenna System. The addition of the
DXE-TVSU-1A
Time Variable Sequencer Unit will produce the correct keying of all devices, to
protect the Active Receive Antennas from high power RF damage. The
DXE-RTR-1A
provides
connection to the transceiver which does not offer a receive antenna input.
Diagram 5
includes the exceptional
DXE-RPA-1
Receive Preamplifier in-line with the main
(transmit) antenna. For many years Amateurs have been requesting a method to employ a receiving
device on their transceivers which lack a built-in preamplifier. The
DXE-RTR-1A
provides this
connection option. Instantaneous receive comparisons between 'preamplifier in' and 'preamplifier
out' are easily accomplished using the
DXE-RTR-1A
MAIN ON - RX ANT - MAIN ON
toggle
switch.
Receiving with the transmitting antenna on a second transceiver or receiver while operating with the
main transceiver connected to a receive antenna is a common contesting application known as
Single Operator – Two Radios (SO2R). This is now easily accomplished by connecting the MAIN
ANT OUT line to the input of the second radio. Reception with the transmitting antenna is safely
interrupted during main transceiver transmissions.
Diagram 6
demonstrates another common use for the
DXE-RTR-1A
and the connections required
for use of a two direction
DXE-RBS-1P
Reversible Beverage Antenna System
.
Diagram 7
shows how a
DXE-RFS-TS2P
Complete Receive Four Square Array Package for Close
Spacing to Transmit Antennas is connected to a transceiver that does not offer a receive antenna
input.
Diagram 8
illustrates the use of the
DXE-RTR-1A
with a
DXE-MBVA-1UP
Multi-band Vertical
Transmit Antenna (a monoband vertical antenna may also be used) one
DXE-ARAV3-1P
Active
Vertical Receive Antenna with Internal Antenna Disconnect Relay, and the
DXE-NCC-1
Receive
Antenna Variable Phasing Controller. This combination allows the user to null strong receive
signals and noise in certain directions, opening up new reception possibilities. When using the
DXE-RTR-1A
, the Multi-band Vertical transmit antenna can be phased with the Active Receive
Antenna using the
DXE-NCC-1
Receive Antenna Variable Phasing Controller. The antennas being
phased should be the same polarization for optimal results.
Refer to the manual for the
DXE-NCC-1
Receive Antenna Variable Phasing Controller (available
for viewing or downloading on the DX Engineering website) for more details on directional signal
and noise nulling.
