May be  ,

Many moons ago , under the  pretence of support for   Sweet pea netting ,
3  short ,  10 ft ish  2 inch  alloy scaffold  poles where sunk  into the
edge of the  garden with the  aid of a  14 lbs sledge , about 18 inches
free , it was long ago..

They  plus the  base of the  mast and others  have  been  in place  30 +
years, as to  the  chemistry ... I know  alloy reacts and forms a layer and 
stops corroding , but
as to continuity etc .. something  is connected out there .

I re vamped  the  connecting cables , as part of the  earth re-works, when
the  500khz  nov arrived, connecting  everything  that  conducted to  the
same   earth bus-bar in the  shed, with individual 35 amp  conduit cable  ,
plus a  few  hidden radials ..that gave an improvement all  round .

System functions well  MF to HF , the  only  thing that  changes  , when I 
change
band is the  Ae tuner .
