Again, the standard mast height is 2 m, but the actual pole height should be chosen according to
the immediate surroundings and obstructions, for example other buildings, tall trees, chimneys,
exhausts etc. The same rule applies in that the mast should be placed at least twice the distance
away, of the height of the tallest obstruction. See Appendix 3.
A 3m pole can be fixed to the side of the building, such as in a TV aerial installation, so that the
lower 1 m is bolted to the wall, and the top 2m is projected above the roof top. This can be done to
the side of a flat roofed building, or at the apex of the roof as appropriate.
If there is a handrail around the roof which is sturdy enough to prevent a person falling off, this could
be used to clamp the 2m mast in place.
Alternatively, a 2m pole can be attached to the roof top itself. The exact method will depend on the
fabrication of each roof, as usually the roof surface cannot be punctured by bolts etc. Sometimes a
large metal plate is used as a mast base, which is then weighted down with concrete blocks.
Your mast pole may have been supplied in one, two or more pieces. If it is in one single piece you
may ignore Section 3.1 and proceed to Section 3.2. If your pole is in more than one piece, following
the joining instructions in Appendix 4 before proceeding.
