DXE-ARAV3-1P - Active Receive Antennas w/ 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
ARAV3-1P
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
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.
Benefits:
Push-pull operation eliminates harmonic distortion
High quiescent current increases ability to handle strong signals without distortion or overload
Meticulous craftsmanship and durable components provide superior dynamic range
RCA type phono jack and type F connector ease installation
Simplified switching - automatic bypass eliminates gain when dc power is off
+13.8 to +18 Vdc power using power connector or through the coax
+13.8 to +18 Vdc through coax enables remote operation at antenna
