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.
Butternut aluminum tubing is machine cut on both ends.
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
Jet-Lube
™
SS-30 Pure Copper Anti-Seize
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.

SS-30 should also be used on all coil clamps, element clamps, bolts and
stainless steel threaded hardware to provide good electrical contact, prevent galling,
allow easier disassembly and to ensure proper tightening.
