Mag Grid Antennas
Grid Sectional Parabolic Antennas for 1.7–2.1 GHz, 2.1–2.7
GHz, 2.4–2.5 GHz
The Mag Grid Antenna series offers a commercial grade product
at an exceptionally competitive price. The die cast reflector is
fabricated using an automated injection molding process which
ensures consistency in performance. The high-grade magnesium
alloy material is lightweight, does not rust, and memorizes the
antenna’s parabolic curve to maintain its shape over time. The result
is the only low cost terrestrial microwave antenna sufficiently
durable to survive changing climate conditions.
The patented grid reflector design provides field reliability and ease
of handling and installation. No secondary coating is required to
prevent rust and corrosion. Breakdown packaging saves freight
costs, and optional factory assembly is available.
Mag Grid series antenna products are also available with an
industrial grade mounting option. This option features a heavier
gauge L-bracket, mast clamp, and u-bolt with mounting centers
compatible for pipes of up to 2.5 inches in diameter. The L-bracket
attaches using 4 previously unoccupied holes in a thicker section of
the reflector. These holes are located farther from the center of the
assembled unit, spreading forces over a wider range of reflector
space. There are no changes to hardware style or assembly and
installation procedures. The result is an antenna very suitable for
higher elevation installations and tower mounts without the cost
and complexity of traditional broadcast tower antenna mounts.
