Manual Updates and Information 

 
Every effort is made to supply the latest manual revision with each product. Occasionally a manual 
will be updated between the time your DX Engineering product is shipped and when you receive it. 
Please check the DX Engineering web site (www.dxengineering.com) for the latest revision manual. 

 

Please

 - Take the time to read the entire manual before you start assembly. There are plenty of 

pictures and drawings to see, and if you read the entire manual first, you'll get a better feel for the 
overall construction methods described. Assembly is not difficult, but there are a number of parts 
that must go together in a certain sequence to make assembly easier.

Site Selection 

 

Select a mounting location clear from power lines, structures and other antennas by a minimum of 
78 feet (68 + 10 ft safety rule). 

Consider overhead power lines, utility cables and wires

. The 

further away the vertical is mounted from local noise sources or other metallic objects, which can 
re-radiate noise and affect the tuning, radiation pattern and SWR, the better. Determine the direction 
you want the antenna to pivot and make sure there is adequate clearance (at least 80 feet). 

 
 

Mounting Pipe 

 

Use a customer supplied 2-1/2" schedule 80, which has an outside diameter (OD) of 2.895", 
galvanized steel thick-walled mounting pipe 

at least

 7-1/2 feet long. This will allow approximately 

4-1/2 feet below ground and 37 inches above ground.  
 
Some manufacturers use the term DOM (drawn over mandrel) which will give you a true OD 
dimension. Other types of mounting pipe may be used but due to lateral strength needed ensure the 
mounting pipe is strong enough. The material most available is ASTM A513 Type 5 which is a 
1020 material. Some pipe suppliers list the material as either 1020 or 1026. Type 1020 has the 
following properties: 
 

ASTM A513 (1020): Up to 2-3/4" OD with maximum wall thickness of 0.25" 
     Tensile: 80,000 PSI.  Yield: 70,000 PSI.  Elongation in 2": 15%.  Rockwell Hardness: B80
