Installing the OMNI- TILT
™ Tilt Base Ground Mounting Pipe
The following is a suggested 2” OD mounting pipe installation. You may want a heavier and/or
longer ground mounted pipe depending on your soil conditions and the type of antenna mast
being used with the
OMNI -TILT™ base. Refer to your antenna’s manual for possible
suggestions. The OMNI-TILT
™
DXE-OTMC-250P Double V-Clamp fits pipes from 1.25” to 2.5”
in diameter.
Wooden Post
The OMNI- TILT
™
Tilt Base can be installed to a customer supplied wooden post or to a ground
mounted antenna mounting pipe. Since there are multiple considerations in mounting to a wooded
post, the customer will have to decide what hardware to use.
Ground Mounted Pipe
Use a customer supplied thick-walled galvanized steel mounting pipe
at least 4 feet long. This will allow approximately 2 feet or more to
be below ground and 20 inches above ground. A thick-walled steel
pipe 1-3/4" OD to 2" OD
maximum is recommended with a minimum
thickness of 1/8" (1/4" preferred) should be used. The standard 1-
1/2" galvanized water pipe (with its 1.9" OD) is just fine for this
application and can usually be found at your local home building
supply store.
For permanent mounting, use a post-hole digger to
make the hole deep enough to accommodate at least 2 feet of pipe and
a couple inches of gravel at the bottom for drainage. Set the mounting
pipe on the gravel, use the pre-mix concrete to fill around the pipe,
adding water and mixing as you fill or mix the concrete first, then
pour in the hole (depends on the type of quick concrete you
purchase). Fill the hole until the concrete is level with the ground
around it. Use a level on the mounting pipe as you fill the hole to be
sure it is vertically straight. Allow to set overnight or per the concrete
manufacturer’s recommendations. Your location, landscape and
ground conditions may require different mounting solutions in order
to have the steel mounting pipe and the vertical antenna in a secure
position. A black vinyl cap (
DXE-VC-2000
for 2” pipe) can be used
to cap the top of the mounting pipe to prevent water and debris from
getting into the pipe.
Note: Galvanized steel, rather than aluminum, is much more suitable for mounting in concrete.
Aluminum will quickly corrode due to incompatibility with the materials used to make
concrete.
Optional Radial Plate to Mounting Pipe
Install the optional patented DXE-RADP-3 Radial Plate on the 2" OD customer supplied mounting
pipe using the DXE-SSVC-2P V-Bolt Saddle Clamp as shown. The standard 1-1/2" galvanized
water pipe (with its 1.9" OD) is just fine for this application and can usually be found at your local
home building supply store. Mount the Radial Plate so you have approximately 1" of space between
