before using the straining screws to tighten the guylines – do not overtighten –
remember that metal expands and contracts with temperature. If installation takes
place in the hottest season of the year, the guylines will contract and shorten as it
cools, so make sure the guylines are not over strained.
c) Make sure the mast is exactly vertical by using the spirit level and adjusting the
straining screws.
d) Repeat with each set of guylines finishing with the topmost, longest set.
10. When the mast has been fully erected remove the temporary guylines and pegs.
c) Fitting the 10 metre mast to a concrete base
Please refer to Appendix 14 which shows the plan for a concrete base.
There is a centre concrete block and six others set out as shown in the plan. The dimensions
do not have to be exactly as shown but can be varied to suit the site. The inner set of blocks
should be between 3.5 and 5 metres from the centre and the outer set of blocks should be
between 6 and 10 metres from the centre.
The mast fits into a socket in a base plate which should be bolted down to the centre block.
The guylines should be attached to eyebolts fixed into the other concrete blocks. There
should be two eyebolts fixed into each block. These can be fixed in place at the time the
mast is erected. If ‘eye’ rings are going to be set in the concrete at the time of pouring they
should be 13mm i.d. and 25mm o.d.
If the eyebolts are to be fixed into the concrete when the mast is erected it will of course be
necessary to drill into the blocks. This will normally be done using a cordless drill and will
require a suitable mains socket nearby in order to recharge the drill batteries.
3.6.4. Mounting of datalogger and sensors
The installation of the datalogger and sensors is the same as for other masts, please see
