Note:  The total loop resistance of the control cable path must be under 30Ω for reliable 

operation. 

 

Note:  

Do not seal the connectors! The connectors are recessed inside a drip edge that 
prevents water from getting into connectors. The cover-to-connector plate 
junction is not sealed so the unit can“ breathe” and eliminate condensation. 

 

Grounding Ports  

 
To ground an inactive port, usually for phased array systems, solder a 
jumper wire between the foil traces for that port as shown. Installing the 
jumper does not enhance lightning protection and is not recommended for 
normal antenna selection applications.

DXE-CW9S - Shielded Control Wire, 9 conductor stranded, per foot 

DXE-CW9S is a high quality shielded outdoor cable.  It features 9 #24 AWG stranded conductors with aluminum 
foil shielding plus a #24 stranded tinned copper drain wire.  This gives you 8 switch positions plus common ground -
 plus the separate shield.  It has a gray PVC jacket. 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.
