 Introduction 

 
Congratulations on obtaining your DX Engineering Four Inch Super Duty+ Base Pivot Assembly 

DXE-VA-Pivot-4

. Now you can have a high-performance pivot base for a vertical antenna with a 

four inch base section. This is the same super duty pivot base assembly used on the 

DXE-

7580FSVA

-3 sixty-seven foot tall vertical antenna. 

 

 
Features

 

 

     

High Strength Super Duty Plus Pivoting Fixture - 

US Patent No. 8,130,168

 

 

Ultra-rugged construction for vertical antennas starting with 4 inch OD heavy wall tubing 

 

Massive Extren

® 

channel insulator 

 

Laser-cut high strength Stainless Steel brackets 

 

All Stainless Steel Hardware 

 
The optiona

DXE-VRW-1

 Manual Winch for easy one-person raising and lowering of your 

vertical antenna is available from DX Engineering. You can move the 

DXE-VRW-1

 winch 

between similar antennas in a multi-antenna installation.  
 
This heavy duty pivot base system requires a heavy duty mounting pipe. Recommended installation 
should provide up to 3" OD heavy wall galvanized steel pipe set in concrete. Schedule 80 pipe that 
is called 2-1/2" has an outside diameter of 2.875" is recommended. 36" of the mounting pipe should 
extend above ground level. Depth of the mounting hole and amount of concrete is dependent on 
your antenna design, local soil type and antenna guying.   
 

WARNING! 

 

INSTALLATION OF ANY ANTENNA NEAR POWER LINES IS DANGEROUS 

 
 
 
 

Warning

:

 Do not locate the antenna near overhead power lines or other electric light or power 

circuits, or where it can come into contact with such circuits.  When installing the antenna, take 
extreme care not to come into contact with such circuits, because they may cause serious injury or 
death. Keep your distance! Remember the 10-foot rule:  When carrying and using ladders and other 
long tools, keep them at least 10 feet away from all overhead lines - including any lines from the 
power pole to your home. 
 

Tools Required 

 
Two 9/16" wrenches, (one of them should be open-end)  
One 7/16" open end wrench 
One 1/2” wrench 
Two 3/4" wrenches
