We sell both retail and wholesale, any quantity... one piece or a truckload! stocks a wide variety of fiberglass, ideal for: VHF and UHF antenna construction, satellite antenna cross booms, masts, quad spreaders (UHF to 40 Meters!), shaft material, open wire feedline spacers, and many other hobby uses. We have the following, in stock, ready for shipment. Click on to see our retail price list. Our company is a wholesale supplier of fiberglass tube and rod to many of the best-known names in antenna manufacturing, both in the ham radio and military markets. From time to time all of these items can be found Vacuum relays and other RF relays Vacuum variable capacitors, "doorknob" capacitors, and transmitting tubes Test equipment, receivers, and transmitters Transformers. 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. Remember that all parabolic antennas, regardless of the material used, must first and foremost, provide a precision reflecting surface. There are two types of fiberglass reflectors, each using a completely different construction technique. At present, these types can be classified according to application, although in the future we may elect to use a single technique for all applications. Currently, antennas used for terrestrial communications, i.e., point-to-point microwave, are of a one-piece construction, that is, they are formed as a single unit on a mold the same size as the finished reflector. Satellite Earth Station Antennas, on the other hand, are of a segmented construction, the segments being high-pressure compression molded. Because ESA''s can be shipped in segments, they offer significant savings for the customer in freight costs and are particularly easy to handle on site, reducing overall installation costs.
