Figure. General construcion of the Spider Quad antenna for 10m.
This 10m antenna was build to test the operation of a Quad
with no boom or a "Spider Quad".
All the element supports are connected to one common point in the
center of the antenna construction.
This test antenna was constructed with easily available, low cost
materials.
The element supports are 2m long plastic tubes with diameter of
16mm.
Better alternative for element supports would probably be fiber
glass fishing rods.
