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 antena 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 antena 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 antena antennas, out there. Our line is designed with the needs of the amateur (ham) radio operator in mind. We carry a wide line of spreaders for quads and quagis...(UHF through 40 meters!), custom crossbooms for the satellite enthusiast, and non-inductive fiberglass masts. Most of our product line is designed to "sleeve" inside adjacent sizes, allowing almost any custom length and wall thickness, while at the antena same time retaining the ability to be shipped via UPS! The ability to ship crossbooms and spreaders via UPS can result in big savings compared to motor freight charges. We offer free tech help to our customers. carries a complete line of fiberglass, including fiberglass round tube, square tube, and solid rod.
