[SCCC] Copper Paste

[Dan Violette]

You will get a boat load variety of answers.  Copper and aluminum are a
corrosion concern, but the grease part helps keep the water out so many love
the copper containing.  Home Depot has various stuff and I have been told
the "Ox-Gard" (a conductive grease which I have gotten there) is the best.
I don't know the conductive material, but it is said to also bite into the
aluminum for good coverage.  These are used for aluminum wiring and are in
the electrical department.  I believe they have the material called
something like Aluminox too.

Subject: [SCCC] Copper Paste

In an attempt to improve my HOA handicapped home station, I have just taken 
delivery of a Cushcraft rotatable multiband antenna. (Geez I miss my half 
acre QTH complete with yagis of years ago.)

The last time I assembled an HF antenna, copper paste was included to 
prolong the integrity of the element joints. This antenna did not come with 
this. I emailed Cushcraft about it but I am sure they will reply that they 
do not feel it is necessary. Past experience tells me this is not true. 
Aluminum joints develop corrosion and insulation between the pieces over 
time.

I think I have some copper paste buried somewhere, but just in case, does 
anyone have a good source for it?
