Cure of thermosetting resin is initiated by heat in the die and catalyst in the resin mix. The rate of reaction is controlled by heating and cooling zones in the die. The resulting high strength profile is cut to length, ready to use as it leaves the pultrusion machine. The controversy over metal versus fiberglass antennas continues, despite the over whelming evidence in favor of fiberglass. This article summarizes the contents of a number of other separate articles which have appeared in the industry media from time to time and is intended, from an objective point of view, to add credence to our claim that fiberglass is better. The ipso facto use of fiberglass, of course, does not guarantee a good antenna and there are a few antenna manufacturers who have "missed the boat" on techniques, which means there are poor quality fiberglass antennas, just as there are poor quality metal antennas, out there.
