[MLB-WIRELESS] Pivoting Mast Problem

[bchild at wireless.org.au]

Hi Jason,

if the pole lengths are 6.5mtrs in length and if i got this rite 1 is
inserted inside the the other, then it's 12.5mtrs high okies.  If that's
the
case yeah a pulley system would be good.

If you were able to get say a couple of ladders that could get up to 6
mtrs, then u could raise the inner section, which 1 would reduce the
stress and strain on the pole as u are raising it up. and to gives it a
lower centre of gravitiy not making it as heavy.

well, if the mast was designed that the centre piece could be lowered down
into itself you could work of the ladder and the base wouldn't have to
move, the same thing as we do with telomasts.
