Assembling the Vertical Sections
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.
The vertical sections of the
DXE-7580FS-VA3
consists of 17 sections of custom engineered 6063
corrosion-resistant aluminum tubing ranging in size from 4" OD to 1/2" OD. The 4" OD section was
already mounted in the Pivot Base Assembly in an earlier assembly step.
It is suggested that the vertical elements be laid out in a line according to size on a flat surface for
ease of assembly. Once all the parts are assembled, the vertical sections should be supported with
either saw horses, chairs or other suitable structures.
When all the vertical element sections are assembled, they will be mated to the Pivot Base
Assembly.
