[TowerTalk] Penetrox/Noalox vs. Anti-seize compound

[john at kk9a.com]

One product is an anti-oxidant for electrical connections and one is to 
prevent hardware galling.  Personally I would redo this before you install 
the antenna.

Hello, all:


I spent a good part of this last weekend assembling a Mosley 4 element beam
from new.  Mosley supplies a small quantity of Penetrox with the antenna and
encourages its liberal application during assembly.  I exhausted the limited
amount supplied and wanted to finish putting things together, so I headed 
for
the local hardware store which carried an anti-seize compound called 
Permatex.
As far as I know, this compound does not contain any particles to promote
conductivity between the joints, but rather is more of a petroleum jelly 
based
lubricant.  Realizing this fact after finishing assembly, I ordered some
additional Penetrox this morning from DX Engineering (they carry both 
Penetrox
as well as Permatex).  When I asked their technical support staff whether it
would be wise to re-do the" Permatex-ed" joints with Penetrox before raising
the beam, he seemed to feel that it would not be worth the trouble to
substitute a more conductive material for the less conductive one.  His r
 easoning was that enough bare aluminum-to-aluminum surface area would 
remain
that the use of the Permatex was very unlikely to negatively effect antenna
performance.  Anyone have an opinion on this?  Should I re-do the joints in
question while the antenna is still on the ground?  Or would this be a 
needless
exercise at this point?


Thanks and 73 de
