DXE-ARAV2-1P - Active Receive Antennas with Internal Disconnect Relay
DX Engineering’s Active Receive Antenna Systems offer excellent receiving performance from 100 kHz to 30 MHz using a whip
antenna element 102 in. long. DX Engineering’s unique design makes it vastly superior to traditional active antennas in both strong
signal handling and feedline decoupling. You get significantly better weak signal reception due to lower spurious signal interference
and reduced noise. This antenna system is ideal for Amateur Radio or Shortwave Listening. The
ARAV2-1P
active antennas ground
the antenna element when power is turned off. These models are used in installations when spacing from transmit antennas is less
than 1/2 wavelength but more than 1/10 wavelength (on the lowest frequency). The units should be used with a sequencer like our
DXE-TVSU-1A
or other reliable means to ensure the units are powered off before any RF appears. Four of these can be used to build
a high performance Receive Four-Square System using our Receive Four Square Controller.
Features
Close Spacing from Transmit Antennas – element grounded at power-off
Sensitive − weak signal sensitivity rivaling full size antennas
Wide Bandwidth – 100 kHz to 30 MHz
Excellent Strong Signal Handling − outstanding Third Order Intercept of +30 dBm
Reduced Noise − quiet FET followers and exceptional feedline shield isolation
Long Life − high quality stainless and brass mounting hardware, metal enclosure
Compact − stainless steel tapered element has low visual and environmental impact
Easy Mounting and Installation Flexibility − pre-drilled mounting plate and universal V-saddle clamps
DXE-RPA-1 - Receiver Preamplifier, 0.3-35 MHz
This is the best HF low noise amplifier available. The RPA-1 is optimized for 0.3-35 MHz
operating range. The push-pull amplifier design and robust components enable it to withstand high
signal levels and operate when you need it most. The dynamic range of the RPA-1 is better than
most receivers. The RPA-1 is suitable for indoor or outdoor installation, with the option of being
powered through the coaxial feed. The metal housing provides shielding and improved lifespan. The
unit uses RCA type phono jack and CATV F connector for the input and output connections, and
has a relay that automatically bypasses the amplifier when dc power is removed.
DXE-NCC-1 - Receive Antenna Variable Phasing Controller
Unlike conventional IF noise blankers, the NCC-1 is designed to reduce noise or interference before it gets to the receiver. The NCC-
1 can be effective on all types of noise, including interference (QRM) from unwanted
signals. The NCC-1 allows the user to continuously adjust both phase and amplitude when
combining two antenna inputs. The signal output to the receiver is the addition or
subtraction of signals from two separate antennas. Unwanted noise can be removed or
unwanted signals can be cancelled. Desired signals can be peaked or enhanced.
The NCC-1 generally works best when both antennas have similar patterns, polarization,
and Signal-to-Noise ratios. For the most effective nulling of noise, both antennas must hear
the same unwanted noise and should have similar polarization. The wanted and unwanted
(QRM and QRN) signals must be arriving from different directions.
Low noise active receive antennas such as the DXE-ARAV2-1P are extremely effective when used with the DXE-NCC-1. For an
economical package of the DXE-NCC-1 and two DXE-ARAV2-1P antennas, see package number DXE-AAPS-1P.
