TLT2

Bore-Sight Antenna Positioning Tower

Features

SunAR RF Motion Antenna Positioning Towers feature innovative design and manufacturing concepts that result in great ruggedness, durability and performance at a competitive price. The new Model TLT2 provides a very stable platform for the largest and smallest EMC test antennas of all types. Variable speed with soft start & stop.

  • New trolley guide concept enhances azimuthal stability
  • Dual load carriers give rigid, stable elevation under heaviest loads
  • Stable boom extension allows proper focal point placement for any size antenna without moving tower
  • Monolithic construction of major components results in unbreakable, lifetime utility
  • Absence of conductive material above the motor box minimizes the electro-magnetic cross section, and minimizes coupling to antennas
  • Materials are selected for resistance to UV radiation and resistance to water absorption
  • Standard model is operated by a single, standard controller channel
  • Developed for indoor and outdoor use
