BASE GUY ASSEMBLY
This arrangement is generally the easiest method of erecting a mast on open ground.
The kit is complete with the mast fittings, 3 guys, adjusters, base plate, ground
stakes and pegs. Foundation bolts are also supplied for mounting on concrete
foundations.
The base plate incorporates a PTFE disk to permit rotation of mast and thumbscrew
for locking in any azimuth direction.
NH and NK kits have polyester guy ropes with adjusters. The NL and NX kits have
galvanised steel guy ropes with conventional rigging screws. The base guy collars
are supplied in two halves to permit easy fitting to mast. The base guy collar should
be set as close to the top collar on the base tube as is practical.
It should be remembered the guys transmit considerable downward thrust on a mast
and should only be sufficiently tightened to restrain movement. When setting up mast
on open ground, the ground stakes should be set at a radius R1 as shown in table on
page 4.
TOP GUY ASSEMBLY
For use in inclement weather
conditions or to give more
directional stability to top of
mast. In some cases, masts will
withstand higher wind speeds,
(see table page 4). This
assembly comprises a
detachable aluminium guy
collar, D shackles, 3 pre-
stretched polyester guys 5mm
diameter, fitted with rope grips,
nylon adjusters and ground
stakes. The guy collar is
supplied in two halves and is
designed to clamp to the upper
end of the second (from top)
section as shown. The specific
guy reference for each mast
can be found on table page 4.
The ground stakes should be
set at a radius R2 as shown in
this table.
Masts with extended heights of 15m or more may require mid-guys for complete
stabilisation, since wind pressure can bow the mast between the ground and the top
guys.
