3.1.4.2.  Short Rope Stubs Method:

 

 

Attach  the  two  short  pieces  of  Polyester  rope  (about  80  cm  long)  to  the  pole  using  a 

“Square  Knot”

  for  each,  positioning  the  two  knots  90°  apart.    See  APPENDIX  for  knot 

instructions.  You will have 4 short stubs of rope hanging down, each rotated 90 degrees 
from the next.  See photo page 10, paragraph 2.4.3. 

 

Attach  each  of  the  4  upper  2mm  Kevlar  guy  ropes  to  one  of  the  stubs  using 

a  “Sheet 

Bend”

 knot to secure them.  See APPENDIX for knot instructions. 

 

Repeat these steps for the lower guy ropes.

 

3.2 

Special Instructions for Erecting the Pole in Windy Conditions

 

This is very important and if you are not sure whether it is too windy or not, then assume it is 
too windy and PLEASE follow these special instructions: 

 

First  of  all,  if  there  is  a  storm  with  very  high  winds,  it  is  probably  better  to  wait 
another day until the storm has passed. When erecting the pole in high winds, you 

must

 have one or two people to help you. 

 

If  it  is  just  a  windy  day,  then  you  will  need  to  temporarily  fasten  the  4  upper  guy 
ropes  to  their  ground  stakes  as  soon  as  you  can,  during  the  process  of  raising  the 
pole.  

 

Continue with the next step, which is directly after fastening the 4 upper guy ropes 
to the guy belts or guy ropes in section 3.1.4.1 or 3.1.4.2.  

 

After fastening the upper 4 guy ropes to segment #9, raise segment #8, dressing the 
wire down it.  Temporarily tape the wire to the pole with electrical tape. 

 

Now fasten all 4 of the upper guy ropes to their ground stakes, leaving about  2.5m 
(8

) of slack in each rope.  To do this, first pull the slack out of the rope, making sure 

the pole  is  still  straight, not bent,  and  then  loosen  the  rope by  2.5m  and  fasten  it.  
This leaves about 2.5m of slack in the rope.  

Do this for all 4 top guy ropes.
