[CQ-Contest] 15m Yagi question

[john at kk9a.com]

At least one of the big US M/M stations uses copper grease. After seeing the
tremendous antenna corrosion in Aruba between stainless steel and aluminum I
have become more cautious about using dissimilar metals in any environment.
Copper is a little closer to aluminum on the galvanic table than stainless
steel is and perhaps the grease keeps the water (electrolyte) out so it is
effective but I do not use it.
