na slowly until a new peak read-
ing is obtained. Lock the peak
reading by pressing the “SHIFT”
key followed by the #2 key. After
the peak reading has been estab-
lished on the leakage meter, the
final position of the dipole anten-
na should be perpendicular to the
actual leakage source.
5. Evaluate the peak reading, if the
meter reading is above legal limit
of 20 mV/m, it will need to be
repaired. Remember if the leakage
reading is greater than 50 mV/m,
the leakage source will need to be
documented, repaired, and report-
ed to the FCC. Note: Always
check with the specific policies of
your cable system regarding FCC /
CENELEC guidelines.
6. Following the leakage detection
process, make arrangements to
have the leakage repaired. After
the leakage source has been
repaired, conduct a follow-up
check for additional or smaller
leaks that could be occurring in
the same area. Use the same
procedures for antenna position-
ing and meter reading as you
would for a new undiscovered
leakage source.

~ Ingress Measurement –
Why and When
The delivery of high quality cable sig-
nal is required by the advanced cable
customer who uses the cable system
for audio, video, Internet, telephony
and digital service transmission.
Though the number of advanced cable
subscribers is limited today; the pre-
dicted need for high quality service will
grow well into the future. With that in
mind, the delivery of high quality serv-
ice to our customers must be a priori-
ty. Futuristic subscribers of the cable
system will not tolerate traditional
analog services that are plagued with
frequency response problems, reflec-
tions, group delays, ingress caused by
inferior components, and poor installa-
tion. The cable industry has advanced
in its techniques to identify and con-
trol egress; we must do a better job of
controlling ingress in order to insure
the growth and development of the
cable industry.
During home installation, the field tech-
nician will verify adequate tap levels,
connect the drop cable to the ground
block, and install all hardware required
for quality customer cable service. In
addition to these basic service respon-
sibilities, the technician should take
responsibility for checking for ingress
and to verify that the cable’s reverse
spectrum is clean. The completion of
