Spacers are not needed on the C3S as the distance between drivers is greater than on the "XR" series where we include an appropriate spacer. However if the three drivers on your antenna are not parallel to one another --- they need to be as this situation will cause VSWR and problems when in high wind. The position with respect to one another is usually off due to the "U" bolts holding the element to the boom to element bracket being tightened incorrectly. You can move the element quite a bit by not having equal exposure left on the "U" bolt. If one side has more than the other half of the "U" bolt showing, it will pull the element off and you are left with an element askew. Please verify that you have equal exposure so all the elements in the driven cell are aligned parallel to each other.
