1. Mount your HD-1 dipole antenna
on the ACTERNA extension pole
and extend the antenna elements.
The ACTERNA pole is 10 foot (3
meters) tall and is made of a non-
conductive fiberglass material.
The most accurate leakage reading
is completed using this type of
FCC / CENELEC compliant pole.
Warning – Electrocution Hazard:
All field technicians should strictly
follow company policy regarding
precautions for using probes and
antennas in the presence of high
voltage power lines.
2. Strategically position the location
of your antenna/pole with regard to
the leakage source. The FCC /
CENELEC requires that cable leak
measurements are to
be made with a reso-
nant half wavelength
dipole held horizon-
tally at a distance of
10 feet / 4 meters
above the ground, 10
feet / 3 meters from
the cable, and 10 feet /
3 meters from any
other conductors (any
metallic objects) in
the vicinity. Metal
objects, including
bucket lift booms, lad-
der racks, and other
conductive hardware
should be avoided.
Metal objects will dis-
tort the radiation pat-
tern of the antenna.
In the event that the
antenna cannot be held 10 feet / 3
meters above the ground and still
be 10 feet / 3 meters from the
cable, the antenna may be held 10
feet / 3 meters above ground and
moved out 10 feet / 3 meters hori-
zontally from the cable.
3. After the antenna/pole is posi-
tioned, turn the dipole antenna
elements to match the direction of
the potential cable leakage source.
4. The field technician should now
scan for the leakage peak. Clear
the old peak readings by pressing
the “SHIFT” key followed by the
auto scale (#3) key to remove any
peaks obtained prior to your final
leakage scan. Conduct a leakage
scan by rotating the dipole anten-
