Cautions

As with any antenna, do not use near electrical wires either overhead or 
buried. 

Use caution whenever using the ground spike to make sure the area is 
clear of buried plumbing or electric wires

.  

If in doubt, do not use the 

ground spike.

Also, use caution with the ground spike as the end is sharp and can cause 
injury.  Do not allow children to play with the antenna.

Assembling the PAC-12

To assemble the antenna, gather the parts that
have been prepared.  In addition to the
components that you have already assembled,
you will need the 2- 12” aluminum rod sections,
coupling nuts and the ground spike (if ground
mounting the antenna).  
If it is available, some aluminum antioxidant
grease will make assembly and disassembly of
the antenna easier as well as maintain good
conductivity between the sections.  Small tubes
of a suitable material can be found in the
electrical sections of most hardware stores
where it is sold for use with aluminum house
wiring and interconnects.  Alternatively, a small
amount of dielectric grease or even engine oil
will work.  Be sure to wipe off any excess to
reduce the chance of it collecting dust. 

 

Screw the ground spike into the grounded side
(BNC shell) of the feed point adapter.  Screw a
12” rod section into the other end.  Place a
coupling nut on this rod and add the second
section of rod.  The loading coil screws onto the end of the second rod.  Tighten all 
connections securely but do not over tighten as the threads may be damaged.
