Warning :
Do not locate the antenna near overhead power lines or other electric light or power
circuits, or where it can come into contact with such circuits. When installing the antenna, take
extreme care not to come into contact with such circuits, because they may cause serious injury or
death.
Manual Updates
Every effort is made to supply the latest manual revision with each product. Occasionally a manual
will be updated between the time your DX Engineering product is shipped and when you receive it.
Please check the DX Engineering web site (www.DXEngineering.com) for the latest revision
manual.

DXE-RTR-1A Receive Antenna Interface for transceivers.
Technical Description
This compact receiving antenna system is designed to operate over a very wide bandwidth from the
broadcast band to 30 MHz with superior strong signal performance. The Third Order Intercept
(TOI) is approxi30 dBm, reducing or eliminating spurious signals.
Exceptional feedline decoupling, absent in some other popular designs, greatly reduces feedline
conducted noise and unwanted signal interference.
The
DXE-ARAV3 Active Receive system requires well fi10 to +15 Vdc @ 60 mA nominal
current. This power must be supplied through the feedline using the included DXE-FVI-1 Feedline
Voltage Injector and wall mounted transformer power supply (also included). Alternatively, well
filtered station power may be used with a 1 amp in-line fuse. If used, the
DXE-TVSU-1A Time
Variable Sequencer Unit or DXE-NCC-1 Receive Antenna Variable Phasing Controller will supply
power for multi-element arrays. The DXE-TVSU-1A Time Variable Sequencer Unit and the DXE-
NCC-1 Noise Canceling Receive Antenna Controller will interrupt the power to the DXE-ARAV3
for proper grounding during the transmit operation of the transceiver.
