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 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 is
vertically straight. 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.
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
The
DXE-MBVA-1UP
shipping boxes contain the vertical tubing sections, an insulated U-channel,
two 3/8" U-Bolts, saddles with hardware, a backing plate, a Tilt Base, UNUN, UNUN Mounting
Bracket, stainless steel element clamps, a black vinyl cap, and stainless steel hardware.
Carefully un-box the antenna and separate the various parts.
Note: DXE-P8A Penetrox™ A Anti-Oxidant
should be used between all antenna element
sections. Penetrox™ A is an electrical joint compound to affect a substantial electrical
connection between metal parts such as telescoping aluminum tubing or other antenna
pieces. It ensures high conductivity at all voltage levels by displacing moisture and
preventing corrosion or oxidation.
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.
