Aluminum Tubing Information
Note: JTL-12555 Jet-Lube
™
SS-30 Anti-Oxidant should be used between all antenna element
sections. Jet-Lube
™
SS-30 is an electrical joint compound to affect a substantial
electrical connection between metal parts such as aluminum tubing or other antenna
pieces. It ensures high conductivity at all voltage levels by displacing moisture and
preventing corrosion or oxidation. Jet-Lube
™
SS-30 should also be used on all element
clamps and stainless steel threaded hardware to provide good electrical contact,
prevent galling, allowing easier disassembly and to ensure proper tightening.
When assembling any telescoping aluminum tubing sections you should take the following steps:
1. Make sure the edges are smooth and not sharp. Deburring may be necessary, since burrs and
shavings can occur on seams as well as edges. All surfaces need to be completely smooth to
allow easy assembly of tubing sections.
Caution
Aluminum tubing edges can be very sharp.
Take precautions to ensure you do not get accidentally cut.
The raised particles and shavings that appear when the aluminum tubing is machined are
referred to as burrs, and the process by which they are removed is known as deburring.
Deburring is a finishing method used in manufacturing. DX Engineering aluminum tubing is
machine cut on both ends and machine slit on one end and you should further assure that there
are no ragged edges or protrusions.
Use the DXE-UT-KIT-DBR for this operation.
2. Clean the inside of the aluminum tubing to clear out any dirt or foreign material that would
cause the aluminum tubing sections to bind during assembly. Do not use any type of oil or
general lubricant between the aluminum tubing sections. Oils or general lubricants can cause
poor electrical connections for radio frequencies.
3. Clean the outside of the aluminum tubing to clear any dirt or foreign material that would cause
the clamps to malfunction during assembly.
4. The use of JTL-12555 Jet-Lube™ SS-30 is highly recommended. Jet-Lube™ SS-30 is an
electrical joint compound which effects a substantial electrical connection between metal parts
such as telescoping aluminum tubing or other antenna pieces. Using Jet-Lube™ SS-30 assures
high conductivity at all voltage levels by displacing moisture and preventing corrosion or
oxidation.
5. When assembling the aluminum tubing sections, ensure the area is clear of grass, dirt or other
foreign material that could cause problems during assembly of the closely fitted telescoping
sections.
