DXE-CW9  - Shielded Control Wire, 9 conductor, per foot 

DXE-CW9-1K

 is a high quality shielded outdoor FTP (Foil Twisted Pair) CAT 5e cable.  It features 4 twisted pairs of 

24 AWG solid wire with aluminum foil shielding plus a solid tinned copper drain wire - providing a total of 9 
conductors for DC switching applications.  It has a polyethylene jacket and is rated for direct burial. This cable is ideal 
for DX Engineering Remote Antenna Switches and Four Square arrays, and should be considered for any low-current 
custom remote switching application you have - such as receiving antenna arrays.  Order by the foot in the length you 
require.  A nice feature is the "rip cord", which allows for easy stripping of the heavy jacket without worry about 
nicking or accidentally cutting the conductors. Excellent for use in all outdoor applications of switching, networking, 
data transfer and phone lines.  As a data transfer line, it supports 10/100/1000Mbps.  

 
 

DXE-CW9-1K - Shielded Control Wire, 9 conductor, 1000 ft reel  

DXE-CW9-1K

 is a 1000 foot box of high quality shielded outdoor FTP (Foil Twisted Pair) CAT 5e cable.  It 

features 4 twisted pairs of 24 AWG solid wire with aluminum foil shielding plus a solid tinned copper drain wire - 
providing a total of 9 conductors for DC switching applications.  It has a polyethylene jacket and is rated for direct 
burial.  This cable is ideal for DX Engineering Remote Antenna Switches and Four Square arrays, and should be 
considered for any low-current custom remote switching application you have - such as receiving antenna arrays. A 
nice feature is the "rip cord", which allows for easy stripping of the heavy jacket without worry about nicking or

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.
