Mounting Pipe; Assembly - DX Engineering DXE-MBVE-5A Instructions Manual

Mounting 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: When installing the MFJ-927 Remote Tuner option at the base of the
antenna - the Mounting Pipe length above ground must be 24 inches to allow
room for the remote tuner and mounting shelf. Refer to the DXE-MBV-ATU-1
manual for details.
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.

Assembly

Carefully un-box the antenna and separate the various parts. All of the element sections are 36"
long. The 2-1/8" OD antenna element is slit on one end and drilled on the other end. All the other
sections are slit on one end except for the top 3/8" OD element.
Note: JTL-12555 Jet-Lube
sections. Jet-Lube
electrical connection between metal parts such as aluminum tubing or other antenna
pieces. It ensures high conductivity at all voltage levels by displacing moisture and
preventing corrosion or oxidation. Jet-Lube
clamps and stainless steel threaded hardware to provide good electrical contact,
prevent galling, allow easier disassembly and to ensure proper tightening.
