Assembling Antenna tracker

This tutorial shows how to assemble tracking antenna.

Note: This antenna requires servos with 180 degree rotation, e.g HK12K from Hobby King or HITEC 645MG.
Other servos like BlueBird 990MG+HK should be modified to obtain full 180 degree rotation.  Refer to this tutorial how to modify this servo.

We recommend use of strong servo with metal gear to achieve good speed and precision of positioning.

Antenna tracker consists ot 3 main parts which should be mounted separately then mounted  together.
