Attaching the 40 meter Wires and the 80 meter Coils for the DXE-NVIS-8040S 

 
1.  Install one 40 meter wire (

A

) and one 80 meter wire with two terminals (

C

) in each side of the 

Balun Bracket for the 

DXE-NVIS-8040S

 as shown. Note in the previous picture, how the 

wires route through the three serpentine slots. 

 
2.  The 80 meter coils are installed by routing and clamping the antenna wires to provide strain 

relief for the coil assemblies. Using Wire 

C

 that is attached to the Balun, route the end through 

the two holes on one of the 80 meter coils as shown. Allow enough slack to avoid sharp bends 
and provide strain relief for the coil. 

 
3.  Using one of the wire clamps, press the wire 

C

 in place in the clamp.  

 
4.  Adjust wire lengths if needed to avoid sharp bends and still allow strain relief as shown. Once 

the wire is in place, install the clamp hardware as shown to hold the wire in place. 

 
 
 
 
 
5.  From the clamp, connect the ring terminal on wire 

C

 to the coil bolt as shown. 

 
 
 
 
 
 
 

 

 
6.  Repeat the same sequence (steps 2 through 5) for wire 

D

 on the other end of the coil (the 17 

foot wire with one ring terminal). 

 
 
 
 
 
 
7.  Again, repeat the above sequence (steps 2 through 6) for the other 80 wires (

C

 and 

D

connected to the other side of the balun.
