Receive 8 Circle
Packages
These packages are built around the DX Engineering Receive 8 Circle Array Controller
and the EC-RCA8 Receive Eight Circle Control Console. They are designed to be used with
eight identical, symmetrically-spaced vertical elements—active or passive—to provide
switching for an eight-direction receiving antenna system. (Passive elements
will generally provide you with a monoband receiving system).
The Receive 8 Circle system uses time-delay phasing (rather than conventional narrow-
band, frequency dependent phasing) to provide eight 45 degree-spaced directional
patterns. The time-delay phasing is directivity-optimized to produce wider and deeper
rear nulls and a narrower main lobe. The result is greatly reduced noise and undesirable
signals for a superior front-to-rear ratio (F/R). Better control of phase and currents
provides a cleaner pattern than found on vertical antenna transmit arrays.
The system also o ers greater reliability in receiving applications. The RC8 controller
uses sealed relays—sized for receiving applications—with oxidation-resistant silver
contacts. Most transmitting four-square switches use large open-frame relays
with exposed brass contacts, which can lead to contamination, oxidation, and
poor conductivity.
The DXE-RCA8B-SYS-2P Controller and Switch Package includes:
• DXE-RC8B-1 Receive 8 Circle Array Controller
• DXE-EC-RCA8 Receive 8 Circle BCD Control Console
• DXE-SSVC-2P Stainless Steel V-Clamp for mounting the RC8B to a 1-2" O.D. post

DXE-ARAV3-8P
Active Receive
Antenna Array Package
The DX Engineering Active Receive Antenna
Array Package contains eight DXE-ARAV3-1P
Active Receive Antennas. They o er excellent
receiving performance from 100 kHz to 30 MHz
while using only 102" whips as the vertical
elements. This results in significantly better
weak signal reception due to lower spurious
signal interference and reduced noise. The
package also includes mounting blocks,
wiring, and mounting clamps.
DXE-ARAV3-8P Active Receive Antenna Array Package ...........................$1,991.60
Complete Electronically Steered Receiving System
• More than 5 S-units of front-to-back on optimized systems
• Works best on 160M, 80M and 40M
• Like having a rotatable Beverage antenna
• Fits in YOUR yard!
• Easily installed—no radials required
