[SCCC] Copper Paste

[Bob Wilson]

Noalox is the "gold standard" - I've seen it at Home Depot in the squeeze
bottles you refer to AWA small tubes. I've also bought large containers at
electrical supply houses and used it for a Caribbean contest expedition. We
donated the antennas, and I heard back 5 or 6 years later that they came
apart like the day they were put up.
