DH Satellite 3M 1 PC Ant 48 Polar or Fixed Series - Manual (Page 2)

INSTALLATION OF BASE:
Look at the drawings below, the first drawing 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 Polar mount you have a choice of two different base assemblies. The first is a base post (see
drawing #2) 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" out of the ground
3. 3m-3.7m ant. 5 '-6" out of the ground
3.8m – 4.2m ant 6’ out of the ground
4.5m-5.0m ant. 7’-0” out of the ground
