the "KITES ON AIR" group
SAN DIEGO, CALIFORNIA USA
For both operator and equipment safety, any
static voltage appearing at the radio end of
kite-antennas should be bypassed to a good
earth ground. A suitable earth ground can
usually be created by metal stake that is driven
into the ground near the radio. This earth
ground will drain away any voltage that might
otherwise accumulate on the antenna feed cable
or antenna wire due to the electric field that
surround the kite when it is in the air.

We also connect the two halves of our dipole
antennas together with a high value resistor
(typically 2 k ohms or greater). This insures that
the charge that builds up on either half of the
antenna will be drained away to ground.

The ground rod that is used to discharge voltage
buildup can also be used as a backup tether
point for the kite in order to keep the kite from
flying away in the event that the primary fly line
breaks or becomes detached from the primary
anchor point. This insures compliance with our
safety rule that two full strength tethered fly lines
should be attached to our kite-antennas at all
times.
