Highlights

Andersen Manufacturing is now offering two new Tx/Rx Antennas.  The 3.8M and 4.2M antennas are hydroformed in a single piece from aluminum, which offers an accurate, smooth parabolic curve.  Each antenna is then segmented into four sections for shipping and rooftop installations.  Segmentation does not affect the antenna's parabolic accuracy.  The reinforced edge of the antenna helps the face of the antenna stay flat during wind loading, allowing the antenna to continue to perform accurately during high winds up to 60 mph.

The advantages of solid aluminum over other materials used to fabricate antennas are as follows:

  • Accurate RMS.
  • No separations or weather cracking.
  • Minimal to no corrosion due to weather or sunlight.
  • Light weight combined with strength.
The 3.8M and 4.2M Tx/Rx Commercial antennas also offer these other enhancements:
  • Simple installation.
  • 4-piece construction, allowing the antenna to be taken on freight elevators to the rooftop for assembly.
  • Reinforced antenna rim.
  • Heavy duty AZ-EL mount for extreme pointing accuracy and stability.
