1.8 m RxTx Class I
Antenna System
TYPE 180TX
The reflector is thermosetmolded for strength and
surface accuracy.
The ASC Signal Type 180TX 1.8 meter
Class I RxTx 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 the
critical parabolic shape necessary for
transmit performance.
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 114 mm
(4.50”) O.D. mast and prevents slippage
in high winds. Hot-dip galvanizing is standard for extreme environmental conditions.
• 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
• Plated hardware for maximum
corrosion resistance.
• Available with C-Band or Ku-Band feeds.
• Hot dip galvanized Az/El mount.
• Designed for typical 1 W and 2 W
