General Information
This compact receiving antenna system operates over a very wide bandwidth with superior strong
signal performance. The output Third Order Intercept (TOI) is approxi30 dBm. This is
significantly better than most aftermarket preamplifiers and receivers - making it one of the cleanest
active antennas on the market, reducing or eliminating spurious signals.
Feedline decoupling, absent in some other popular designs, is also exceptionally good. Decoupling
the shield greatly reduces feedline conducted noise and unwanted signal interference
The
ARAV3
systems can be affected by local noise sources. Local noise can be random or
directional in nature. Every effort must be made to locate sources of noise that could be eliminated
at the source. Dimmer switches, electric timers, photocell-operated security lights, and many other
items can be sources of unwanted noise. If the noise source is directional in nature, using two
ARAV3
antennas in conjunction with the
DXE-NCC-1
Receive Antenna Variable Phasing
Controller would allow the user to phase out the noise being received. Plasma-screen television
receivers are a known generator of unwanted noise interference. Most modern LED or LCD flat
panel televisions are not broadband noise generators.
The
DXE-ARAV3
active antennas may be used in installations when spacing from transmit
antennas is at least 1/10-wavelength or more. Ideally your receive antenna should be a minimum of
1/2-wavelength away from any transmit antenna (on the lowest frequency) to avoid mutual coupling
and the transfer of any noise being re-radiated by the transmit antenna. The
DXE-ARAV3
series
active vertical antenna system grounds the antenna element when power is turned off for protection
of the active devices.
When using active receive antenna radio systems with RF amplifiers a sequencer such as the
Time Variable Sequencer Unit
should be used. This will ensure the correct timing
while switching from receive to transmit, and back to receive, so the active receive antenna is
protected from high energy fields from the transmit antenna.
Systems Packages
There are 4 Vertical Active Receive system packages. (DXE-ARAV3-1P, -2P, -4P, -8P)
Note:
Export versions have a
-E
after the part number and contain the
DXE-WP102E
three
piece antenna element rather than the one piece antenna element. The three section
tapered stainless steel whip with machined couplers was designed to be compact in size
for economical export shipping purposes.
