Station transmitter to Four Square Phasing Unit:
50 Ω coaxial cable, any length.
Four Square Phasing Unit to Dummy Load:
50 Ω coaxial cable, any length.
Call DX Engineering for custom made lengths of coaxial cables for

Transceiver to the Four Square Phasing Unit, 50 Ω, with PL-259 connectors installed.
Four Square Phasing Unit to dummy load, 50 Ω, with PL-259 connectors installed.
The correct
electrical
length 75 Ω coaxial cable in sets of four with PL-259 connectors
installed for the four feedlines going from the Four Square Phasing Unit to the Vertical
Antennas.
Control Wire Connections
Good quality
DXE-CW9
CAT5 control cable is available from DX Engineering (or equivalent) is
recommended for connection between the Four Square Control Console and the Four Square
System Phasing Unit.
The
DXE-CW9
CAT5 cable has #24 AWG wire. Based on current and voltage drops, CAT 5 cable
is capable of running 400 feet from the Four Square Control Console to the Four Square Phasing
Unit.
For control cable runs from 400 feet up to 750 feet, doubling up the wire pairs of the
DXE-CW9
CAT5 cable (two wires per connection) will effectively make the wire gage go from 24 AWG to 20
AWG, thus allowing longer runs between the Four Square Control Console and the Four Square
Phasing Unit.
DXE-CW9
CAT5 UV resistant cable (or equivalent) is recommended as it also has a PE
(polyethylene) jacket for long lasting direct burial.
The Four Square System Phasing Unit and Four Square Control Console use the same type 5
terminal plug labeled “
GABCG
”. The terminals use the same connection letters and are connected
G to G, A to A, B to B, C to C. Either or both "G" terminals may be used for the ground connection.

On both the
Four Square Control Console
and the
Four Square System Phasing Unit
, the green
connectors, as shown in
Figure 4
, are in two parts and the top part can be removed by pulling it
straight off. This will allow easier wire replacement or servicing as needed.
