So I'm still QRT; apart from a brown-out on the rig, the support on the inverted-vee toppled over in high winds.
Thanks to the topple-over I discovered the conductors (SWG 16 bare copper) had started to turn greenish-black; a sure sign of oxidation. This may be because I was QRT for a while before the mast came down. It could probably happen of it's own accord eventually even if the station were on the band with any regularity.
My antenna was an inverted-vee with exposed conductors. It may possibly happen on other wire antennas (sp. antennae??) as well.
Which brings me to my questions
- Does oxidation of the antenna elements have any impact on the signal quality of the station?
- Is there a simple mechanism to avoid/mitigate such oxidation on the antenna elements?
- E.g. Use a laminated conductor instead of bare
- Is any regular maintenance activity necessary on an antenna?
- E.g. In my case, how much should the conductors be allowed to darken before replacing/abrading/scoring the conductors?
