Philips SDV2940
Indoor/Outdoor UHF/VHF Television antenna
Antenna grounding
If an outside antenna is connected to the receiver, make sure the
antenna system is grounded so as to provide protection against volt-
age surges and built up of static charges.Section 810 of the National
Electrical Code,ANSI/NFPA No.70-1984, provides information with
respect to proper grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna discharge unit, size of
grounding connectors, location of antenna discharge-unit, connec-
tion to grounding electrodes, and requirements for the grounding
electrode. See DIAGRAM TO LEFT.
Important Safety Notes
If you do not feel comfortable or competent to install this antenna
we recommend that you seek the assistance of a qualified
professional antenna installer.
Read the instructions for this device thoroughly before
attempting installation.
The installation or dismantling of any antenna near power lines is
dangerous. Each year hundreds of people are killed or injured while
attempting to install or service antennas.For your safety and proper
antenna installation, read and follow all safety precautions.
Outdoor antennas and lead-in conductors from antenna to a build-
ing should not cross over open conductors of electric light or power
circuits.They should be kept away from all circuits to avoid the pos-
sibility of accidental contact.
Each conductor of a lead-in from an outdoor antenna should be con-
nected with an antenna discharge unit. Antenna discharge units (or
Lightning Arrestors) should be located outside the building between
the point of entrance or the lead-in and the
TV,
and as near as prac-
tical to the entrance of conductors to the building.
Choose an installation site for safety as well as performance.
All electric po
w
er lines, cable lines and telephone lines look alike.
To be safe, assume ANY overhead line can kill you.
Do not place an antenna where it could potentially fall on to,or blow
into a power line. If in doubt call your electric provider. Let them
review your site.
