Introduction
This manual covers both the
DXE-RSEAV-1
and the
DXE-RSEAV-1FVI
. The
DXE
RSEAV-1FVI
is exactly the same but comes with the
DXE-FVI-1
DC Power Injector.
Class leading performance makes the DXE-RSEAV-1 Receive Short Element Active
Vertical Antennas the best choice on the market for VLF through HF reception, including
long distance AM broadcast, Medium Wave and Shortwave (SWL), new low frequency
Amateur bands, DXing, contesting and everyday HF operations.
DX Engineering Receive Short Element Active Vertical Antennas (
RSEAV
) offer
excellent low noise radio frequency reception from below 100 kHz to above 30 MHz. They
include a high quality three-section 8.5 ft. (2.6m) aluminum tubing whip, mounting plate
and the all new Active Matching Unit
DXE-AVA-3
(also sold separately). When deployed
in the appropriate location, RSEAV antennas provide significantly better weak signal
reception than other actives and full size transmit-capable antennas due to reduced noise
and lower spurious signal interference, making them the best choice on the market for
DXing and contesting in Amateur Radio, and for long distance AM and Shortwave Listening (SWL).
Each Receive Short Element Active Vertical Antenna is intended to be mounted on a ground rod at ground
level in a clear area away from all metal, towers and other antennas. They are sold individually and in sets of
2, 3, 4 and 8 elements for use in phased array systems.
At the heart of the RSEAV Antennas is the
DXE-AVA-3
Active Matching Unit. Its state-of-the-art
broadband operational amplifier design works as a high impedance buffer for the connection to a short
element of 6 to 24 feet. It achieves unparalleled weak signal reception with these features and benefits:
• Ultimate frequency coverage of 40 kHz* to 30 MHz for VLF through HF (including the 2200m and
630m Amateur bands)
• High Third Order Intercept (TOI) Perfo39dBm for superior strong signal handling equal to top
transceivers
• Consistent unit to unit gain for greatly improved array performance
• Virtually Flat Gain (+/-0.4 dBm) across the entire frequency range
• Internally settable gain (default -6, 0, or +6 dBm) for different ambient noise
locations and element sizes
• Direct DC via second F connector – internal settable choice for separate DC and RF
coaxial cables for best performance, or standard Bias Tee DC on the RF coax
• Each
DXE-AVA-3
Active Matching Unit operates on 12 -15 VDC at 25mA
• Element is grounded when power is removed
• 75 ohm F connectors support field serviceable RG-6 Quad Shield suitable up to 1,000
feet for VLF through HF
*Frequency coverage below 100 kHz requires Direct DC on a separate DC only coaxial cable.
THIS IS A RECEIVE-ONLY SYSTEM
You should never attempt to transmit through the system.
The use of bypass relays and sequential timing is required to avoid damage to the receiver and active
antennas in the proximity of transmit antennas.
Do NOT place any active receive system on the same mast or tower as the transmit antenna.
