Feedline Connections

 

 
The 

DXE-UN-43

 UNUN is attached to the feedline antenna connection using the 

DXE-TCB-

UNFK 

- UNUN Feed Point Connection Kit which contains two pre-drilled copper tinned braids for 

connection to the vertical antenna system.  Both braids are 1" wide by 9" in length. Connect one  
braid from the antenna feedpoint located on the base section of the antenna to the terminal on the 

DXE-UN-43

 UNUN closest to the 

Red "+"

  on the label as shown in 

Figure 17

. Do not over 

tighten the wing nuts. Hand tighten them only, do not use pliers or other tools to over tighten the 
wing nuts. 
 
Connect the other 9" braid from the terminal on the 

DXE-UN-43

 UNUN closest to the 

Black 

"

▬"

 on the label to the closest radial wire bolt on the optional 

DXE-RADP-3

 Radial Plate as 

shown in 

Figure 17

.  Route both braided cables as shown.
