Being a white stick radio operator, I have to find someone to
put the antenna up on the chimney stack for me, but before I
do, I need some advice please.

Obviously, a small pole needs to be attached to the chimney
stack so that the antenna which is a glass fibre aerial
weighing 0.9Kg can be fitted just above the stack itself.
Neither I nor my neighbour have chimney pots.

I would estimate that the pole would be overall about 3 feet
long and then the antenna fitted at the top of the pole to
clear the stack.

Should I use 1 or 2 lashing kits to hold the pole. The pole
will be 2" alli scaffold, already obtained, curtousy of the
housing refurbishment contractors.

I have written consent from my neighbours because the chimney
stack belongs to both of us.

I asked on another group but advice not forth coming.

Kindest regards,

Jim

Stick a pole in the ground it much easier to take down when you
need to put up another type of ariel. The ariel can be 15M from
ground level. A tempory wind up / down one can be as high as
needed.

Frustration casues accidents: allow faster traffic to overtake.

Many thanks for the suggestion, but unfortunately, this is not an
option.

For the obvious reasons that a pole would be subject to much more
wind loading, that could result in it coming down in a storm and
putting next doors windows through.

How do you work that one out? I would prefure to repair a window rather
than a chimney.
