The reflector is thermosetmolded for strength and
surface accuracy.
The ASC Signal 1.2 m Type 120
Offset 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 Az/El mount is constructed from
heavy-gauge steel to provide a rigid
support to the reflector. The Az/El mount
secures the antenna to any 73-76 mm
(2.88”-3.00”) O.D. mast and prevents
slippage in high winds.
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.
• Single bolt fine elevation adjustment.
• Galvanized 19 mm (.75”) O.D. feed
support legs.
• Factory pre-assembled Az/El mount.
• Plated hardware for maximum corrosion resistance.
• Available with a wide variety of
C-band or Ku-band feeds.
