This mounting pipe must be permanently mounted in the ground, preferably in a concrete base 2
feet by 2 feet by 4 feet deep (with gravel below for drainage). The antenna system requires this type
of mounting to help withstand the lateral forces present on the
antenna during wind conditions and when operating the pivot
function. Make the hole deep enough to accommodate at least 4
feet of pipe and 4 to 6 inches of gravel at the bottom for drainage.
Set the mounting pipe on the gravel, use the concrete to fill
around the pipe per the concrete instructions. 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 the mounting pipe is
vertically straight.
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.
Coaxial Cable to Mounting Pipe
The coaxial cable should be routed to the base of the antenna system and be buried below the radial
system. PVC Conduit pipe may be used to house the coaxial cable. Bury the cable 6" to 12" below
ground level.
Radial System
The use of a radial system is a key requirement for a high performance
quarter wave vertical antenna system. With a vertical antenna system,
the radials are the second half of the antenna. The radials contribute to
the radiation efficiency of the entire vertical antenna system.
At a minimum, 32 radials, each 65 feet long, should be used with this
antenna.
DXE-RADW
Radial Wire, a 14 gauge stranded copper with a
black relaxed PVC insulation wire is suggested for the best results.
The wire radials should placed as symmetrically as possible straight
from the feedpoint around the vertical antenna and spaced evenly,
regardless of how many radials are used. Do not cross or bunch any radial wires as this nullifies
their effectiveness. If you have limited space, put in as many straight radials as you can. The radials
must be connected to the shield of your feedline. The
DXE-RADP-3
Stainless Steel Radial Plate is
an ideal optional item which provides an excellent system for attaching radial wires to your vertical
antenna system feedpoint.
