There is a jim=dandy product called NoAlOx or Noalox, I forget which,
available at electrical supply stores. It is a conductive grease
designed for use on al-al and al-cu connections in house wiring. I have
used it with good success on antenna element joints as well. I also used
it with good success on golf cart battery terminals  pb-cu, with no
ill effects noted. As Rick's message would suggest, there have been
a goodly number of house fires in homes with Al wiring, due to lack
of retightening. Some homes use all aluminum, and some only use it in
the high-current 220v applications (pronounced "expensive conductor")
applications, which ain't a helluva lot better. Ugh.
