It's a log aeriel though, so cannot be that old. They were
rarely seen before the ?700Mhz clearout. How would galvanic
corrosion be the cause ?. It is aluminium and clamped to
an alloy pole.

Sounds like some robust crows have been trampolining on it.

There are sets of plastic spikes made for keeping birds off - don't use
metal spikes! Vertical polarization for a relay wouldn't allow birds to
land, especially on a log periodic aerial.
