Install Ground Radials. For ground-mount installations, we suggest a
minimum of 16 radials, each at least 13 feet, 5 inches long spaced as evenly
as possible around the S9v base. For best performance, use 32 (or more)
radials. It is suggested that you use 14 -16 AWG insulated stranded copper
wire (available at Home Depot
TM
and sold in a 500-ft roll for around $35). S9
sells ring terminal connectors to facilitate connecting the radial wire to the
ground plate.
Use lawn and garden fabric staples from Home Depot
TM
or Lowes
TM
to secure
the radials to the ground. Install the first staple about 3 inches or so from the
edge of the radial plate. Grass will eventually grow over the radials and cover
them. In the meantime, be sure to set your lawn mower blade higher than
normal to ensure that the radials do not get caught in the mower blade - this
advice comes from real-world "experience" (!). It is best to use at least 5
staples per radial to ensure the radials are held firmly against the ground.
