If desired, connect a fused external power source to the
ANT PWR
2.1 mm center-positive
jack if you are not using the
NCC-1
supply to power antennas (HD4 Jumper
Selectable). The allowable voltage range is 10-30 Vdc with 300 mA maximum
load current for both INPUTs combined. The DX Engineering
DXE-ARAV3
Active Receive antennas typically require a nominal 12 Vdc @ 50 mA each.
Radio Interface Diagrams
The following typical interface diagrams are shown for the
DXE-AAPS-1P Active Receive
Vertical Antenna Phasing System
.
The
DXE-ARAV3
receive antennas must be at least 1/10-wavelength away from any transmit
antenna and preferably more than 1/2-wavelength away. The
DXE-NCC-1
switches the power off
during transmit. This configuration allows the operator to selectively null out interference, and
thereby enhance the desired received signal direction ability.
Every radio manufacturer and every amateur radio operator's location is different. The following are
only suggestions, and you should consult your radio manufacturer's manual for details and further
requirements.
