• Connect your leakage detection
meter to the dipole antenna/pole.
• Rotate the antenna to a position
that matches the polarization of
the vehicle mounted antenna.
• Pre-adjust the leakage source to
generate the desired leakage level
that you would like to measure
with your meter. For example,
select a desired leakage at 20 µV/m.
Note: Some cable system services
may require you to select a desired
leakage at a higher level (e.g. 50
µV/m). Check with your supervisor.
5. Use your leakage detection meter
to measure the leak level from your
known source.
• Turn your leakage meter “ON” .
• Press the green “SHIFT” button
and press the leakage button.
Your screen should say “Leakage”
at the top of the screen.
• Check your screen, your meter
should be in
“Measurement”
Mode. If your meter is in “Find
and Fix” Mode, press the Left Soft
key until measure is highlighted.
• Check the antenna icon at the top
of your screen.
a. The correct antenna for the cali-
brated leak, at this stage,
should be the
dipole.
b.If the dipole antenna is not on
your screen at this point, use the
middle Soft key to choose the
antenna icon until you have the
dipole antenna on your screen.
• Enter the reference distance
according to the regulations (10
feet – FCC; 3 meters CENELEC)
in the setup menu.
• Enter the actual distance in the
leakage screen (the distance from
the leakage source to the spot
where the vehicle antenna is to
be calibrated).
• Using your leakage meter, read
and record the leak level.
•
Shut your leakage meter off for
now, as the level of your leakage
source is known. Shutting your
meter off at this point will also save
energy on your meter’s battery.
6. Calibrate vehicle-mounted antenna.
(step c. see illustration, page 4-5)
• Drive your patrol vehicle approxi-
mately to the same location as
your current dipole antenna set-up.
• Mount your vehicle antenna
(monopole or dipole) on the top
center of your patrol vehicle roof.
• Connect your meter to your patrol
vehicle docking station or directly
to the antenna’s cable, if a dock-
ing station is not available.
7. While in your vehicle, set-up your
leakage meter with the vehicle’s antenna
• Turn your meter “ON”.
