Mounting Pipe - For all versions of the Tilt Base
Use a 1-3/4" to 2" OD thick-walled galvanized steel mounting pipe at least 4
feet long. This will allow approximately 2 feet to be below ground and 2 feet
above ground. A thick-walled steel pipe 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 a hole deep enough to accommodate 2 feet of pipe and a
couple inches of
gravel at the
bottom for
drainage. Set the
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. Fill the hole until the concrete is
level with the ground around it. Use a
level as you fill the hole to be sure the
pipe is straight.
Figure 1 - Tilt Base Mounting
Allow to set overnight. 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. You may also attach the Tilt Base to a
wooden post at the location you intend to use the antenna, making sure the unit is securely mounted.
When using the optional
DXE-RADP-3
Radial Plate, allow approximately a 7" clearance (
Figure
1
) from the Radial Plate surface to the bottom edge of the Tilt Base.
Note:
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.
Note: UMI-81343 Never-Seez
®
or DXE-NSBT8 Anti-Seize should be used
on all clamps, bolts and stainless steel threaded hardware to prevent
galling and to ensure proper tightening.
