concrete.   Though  concrete  will  provide  a more  secure,  permanent  base for your 
antenna, it will be difficult to remove or re-position later.  The assembly should be 
inserted  about  12-24

”  into  the  ground,  exposing  24-36”  of  the  assembly  above 

ground. 

 

It  is  suggested  that  the  antenna  be  tried  in  an  area 
using  the  permanent  mounting  assembly  in  a  hole  in 
the  ground  before  concreting,  in  case  the  antenna 
needs  to  be  moved  later.   Once  you  are  sure  of  the 
location  for  the  antenna,  the  Permanent  Mounting 
Assembly can be concreted into place, if desired. 

 

Warning

:        The  fiberglass  insulating  rod  is 

not 

hammer-proof.        Do  not  pound  the  Permanent 
Mounting  Assembly  into  the  ground  like  a  stake. 
Permanent  damage  to  the  fiberglass  insulating  rod 
could  occur.   If  it  is  necessary  to  drive  the  assembly 
into  the  ground,  first  remove  the  fiberglass  insulating 
rod  using  a  5/

32”  Allen  wrench  and  a  7/16”  socket. 

Drive  the  aluminum  permanent  mounting  tube  into 
the  ground  using  a  rubber  mallet.    Alternatively,  a 

conventional  hammer  can  be  used  if  a  wooden  board  is  laid  over  the  aluminum 
mounting tube before striking. 

 

3)  Assemble  antenna.   

First,  attach  the  bottom  section  to  the  middle  section, 

making  sure  to slide  the pieces  completely  together.   The  ¼

” slots  on the end of 

the middle  section should  engage  completely  with the stud of  the clamp  knob  on 
the end of the bottom section, as shown in step 1 below.  Tighten the clamp knob 
snugly. 

 

 

 

 

 

Second,  attach  the  middle  section  to  the  top  section  as  shown  in  step  2  below. 
Again,  the  clamp  knob  stud  should  fully  engage  with  the  slots  on  the  end  of  the 
top section.  Tighten the clamp knob snugly.
