Depending on your geographic location, various dealers should be able to supply the mounting post
you specify. The following dealers can supply DOM tubing: (Other dealers in your area may be a
better choice.)
Industrial Tube & Steel, Corp.:
On Line Metal Store:
Speedy Metals:

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.
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 Suggestions
The use of a radial system is a key requirement for any 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 most low
band vertical antennas.
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
