Assembling the Dipole 

Center-T Support

 

The center-T support has pre-drilled holes for attachment of the wire elements, feedline and 
support rope.  
 

Support Line 

The center-T support’s top hole is used for the attachment of a messenger line that is used to 
provide support for the antenna wire and feedline. The use of the messenger line, which is 
strongly recommended, will reduce the stress on the element wires and keep the antenna from 
stretching over time, which will change its resonant frequency. 

 

 

Ideally, the messenger line should attach to the same structure used for the dipole, only above it, 
forming at least a 30 degree angle between the dipole and the messenger line to support the 
antenna. See 

Figure 2

Example Mounting Diagram 

 
The included Dacron rope should be used for the messenger line by forming a loop at the mid-
point of the rope. Push this loop through the center-T support top hole, then pull the rest of the 
rope through the loop.

 

See

 Figure 3.

The excess rope can be used to attach the antenna end-insulators to the support structures. Use 
the same structures used by the messenger line if possible. The ends of the rope should be 
cauterized with a small flame to prevent the rope braid from fraying.
