DH Satellite 60 Heavy Duty Polar/Powered Dec - Manual (Page 4)

INSTALLATION OF BASE POST
With this polar mount you have a choice of using the factory TX base stand (page 5) or
using a base post. If you are using a post, please be sure to check with an engineer to
determine the reinforcing required on this single post. DH Satellite will not engineer post
designs. When placing your post in the concrete be sure it is plumb. The following chart shows
how much of the post should be out of the ground for the different size antennas.
3.0M antenna. . . . . . . . . . . . . . . . . 5’ 0” out of ground
