A Different way to construct a tried and true antenna out of PVC. Before you shake your head about PVC go to the PVC and sunlight study. Especially for the 10 meter and higher frequencies. By KB3TTP.
In the photo at left you can see the simple attachment points for the support strings. A small hole was drilled in an area where there is a joint so that the medium sized eye screw can can catch both pieces of pvc for a strong hold.
The cord used is 3/32 Dacron. Dacron is needed to hold up from degrading in the sunlight.
This arrangement stiffens up the whole assembly and helps prevent the spreader arms from bending over. This will keep a good alignment of the spreader arms to hold the antenna wires close to their optimun desired measurments.
