BASE ROTOR INSTALLATION

This page shows you how to mount a rotor to the base of a Spiderbeam Aluminum Mast, using a Spiderbeam Tripod (Quadpod) and Spiderbeam Rotor Base-Mount Set.

 

 

 

ROTOR BASE-MOUNT SET

FOR ALL SPIDERBEAM

TRIPODS AND MASTS

 

Shown here with home-brew Rotor Adapter to the mast.  

We strongly recommend using the appropriate Spiderbeam Rotor-Adaptors instead of

home-brewing the top mount.

ROTOR ADAPTERS

 

The bottom segment of all Spiderbeam aluminum masts is too large to fit inside of any common rotor. Spiderbeam has produced a family of special rotor adapters for adapting any Spiderbeam mast to any common rotor.

 

  • The top half of the rotor adapter is either 65mm (for 70mm mast segments) or 75mm (for 80mm mast segments).
  • The bottom half is either 60mm (for large Yaesu Rotors), or 50mm for smaller Yaesu rotors (G450 and G650) and for all Hy-gain rotors.

 

Together, the Spiderbeam Aluminum Mast, Tripod, Rotor Adapter and Base-Mount Set provide users with a sturdy, lightweight, and easily transportable solution;  perfect for Spiderbeam Yagi antennas as well as other lightweight HF and VHF antennas.
