Introduction
Congratulations on your purchase of the DX Engineering Receive Eight Circle Array System
designed by W8JI, which offers the best directional receiving performance in proportion to the
space required. Advanced design, with a stable, clean, narrow and low-angle pattern in eight
selectable directions, makes the DX Engineering Eight Circle Array the ultimate receiving antenna.
The Eight Circle Array System is an eight element, eight direction-switchable array based on a
four element end-fire/broadside combination of short receiving vertical elements. This antenna
array is capable of delivering pattern directional performance superior to standard or short Beverage
or reversible Beverage systems, and typical three element or four square arrays of short vertical
elements. The DX Engineering Receive Eight Circle Array System offers selectable directional
performance comparable to
eight very long phased Beverages, and does it in far less space.
Advantages of this DX Engineering Receive Eight Circle Antenna System over other arrays:

W8JI design with stable, narrow and low-angle pattern

Directional performance varies with circle radius

Included Active Receive Verticals with 8.5 foot elements cover a
single band or multiple bands within 500 kHz to 30 MHz

Excellent directivity in a smaller space than phased Beverages for
better signal-to-noise ratio

Reduced susceptibility to high angle signals compared to phased
Beverage antennas, as well as superior performance over EWE,
Flag, Pennant, K9AY antennas.

Switching console selects one of eight 45° spaced directions

Directivity over a very wide frequency range

Less physical space and less maintenance required than phased Beverage antenna arrays

Enhanced relay contact reliability

DC powered control console allows system operation without AC power mains
The
DXE-RCA8C-SYS-4P is a complete Receive Eight Circle Antenna Array Package which may
be installed as a Mono-Band or Multi-Band system using a recommended or alternative array radius
for the frequency coverage desired. A single delay line can be made to accommodate the desired
band or bands of operation according to the information provided in the
Delay Line section of this
manual.
