TYPE 845
The reflector is thermosetmolded for strength and
surface accuracy.
The ASC Signal 84 cm Type 845
Elliptical Antenna is a rugged
commercial grade product suitable for
the most demanding applications. The
reflector is thermoset-molded for strength
and surface accuracy.
Molded into the rear of the reflector is a
network of support ribs which not only
strengthens the antenna, but also helps to
sustain its critical parabolic shape.
The pole mount is constructed from
heavy-gauge steel to provide a rigid
support to the reflector. A specially
formulated powder paint process offers
excellent protection from weather related
corrosion.
• All materials comply with EU directive No. 2002/95/EC (RoHS).
• One-piece thermoset-molded offset
reflector.
• Factory pre-assembled Az/El mount.
• Plated hardware for maximum corrosion resistance.
