DH Satellite 1PC or 8PC 4.2m & 4.5m 48 Polar/Fixed Mount - Manual (Page 2)

INSTALLATION OF BASE:
Look at the figures below, FIG. #3 shows the recommended concrete base. In areas of deep frost we
recommend that this base go below frost levels. 1/2" rebar can be used to reinforce the structure, if required;
contact your local concrete people or a local Engineer to give you an idea of how much steel to use.
WE
RECOMMEND THAT YOU CHECK WITH A LOCAL ENGINEER TO DETERMINE SOIL TYPE AND
BEARING TO VERIFY THAT THIS BASE WILL WORK FOR YOUR LOCALE.
With this mount option you have a choice of two different base assemblies. The first is a base post (see FIG. #3)
The base post is simply a 5" I.D. / 5 1/2" O.D. pipe that has one or more weldments on the lower section. We
recommend that the post be in the concrete at least 4 '-0". When the post is set in concrete, be sure it is plumb.
The following chart shows how much of the post should be out of the ground for some of our antennas.
3.0m ant. 5’ 0” minimum out of ground
3.7m – 3.8m ant. 6’ 0” minimum out of ground
4.2m – 4.5m ant. 7’ 0” minimum out of ground

The second option is using either
a square foundation or a sono
tube as shown in FIG. #4
