now carries the fine products of including their lines of tower sidearms (mounts which hold small to medium weight antennas from 24 to 36 inches from the tower leg so that distortion of the antenna pattern by close proximity to the tower is minimized) as well as the "Sidewinder", a rotating side mount which allows antennas (including HF beams) to be mounted on the side of the tower and still be rotated as much as 315 degrees. products use quality aluminum, T.I.G. welded for clean, solid joints, as well as stainless hardware for long, trouble-free life. Custom work is welcomed, TIG welding aluminum, steel, and stainless steel. Visit our page or our Antenna Magic Interested in very lightweight, low-profile wire beams, loops, and quads for HF? Both constructions use the same type of material, basically a thermoset FRP (fiberglass reinforced plastic), which includes specially formulated resins, flame retardants and UV stabilizers to produce the unique benefits which characterize fiberglass reflectors. Because some antenna installations must exist in environments containing many corrosive agents, the materials in the construction of the antenna must be carefully selected to alleviate corrosion problems. Obviously, in the case of an aluminum structure, dissimilar metal contact is always a risk factor. A fiberglass dish, on the other hand, all but eliminates this problem - for obvious reasons. The resins used in antennas have been subjected to both field and laboratory tests involving over 130 highly corrosive chemicals at temperatures up to at least 120° F (50° C), with results that indicated little or no detectable degradation of the test samples. Many of these antennas are ideal for restricted spaces and portable applications. has an extremely good site called "Antenna Magic", which is devoted to antennas of these types. Photos, performance plots, and practical experience on Reflected M beams, wire beams, quad loops, super lightweight quads, "quickie" verticals, elevated half squares, rotatable self-supporting dipoles, and even the quad is PACKED into this large and informative site. and other parts which make assembling these antennas very easy, and (of course) you can get your fiberglass here at the MGS website. Check out "table 1" on the Antenna Magic site, then look at specific antennas to determine the materials you will need.
