Assembly Notes - DX Engineering DXE-7580FS-VA Manual

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 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.
Radial wires can be laid on the roots of the grass using DXE-STPL Radial Wire Anchor Pins to
hold them down. Using enough staples will ensure the wires will not be snagged by mowers,
people, or animals. Grass will quickly overgrow the radials and it will be virtually impossible to see
them. An article describing this process is available on the DX Engineering website in the Tech
Info section. Radials can also be buried just under the surface by using a power edger to make a slit
in the soil.

Assembly Notes

Note: DXE-P8A Penetrox A Anti-Oxidant should be used between all antenna element
sections. Penetrox 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.
Note: The following assembly instructions are based on using a customer supplied
2.895" OD Mounting Pipe (referred to as 3" OD), with the optional DXE-
VR-1 Manual Winch, optional DXE-RADP-3 Radial Plate with one optional
DXE-SSVC-3P V Clamp and one optional DXE-112-KIT - Chassis Mount
SO-239 Connector.
