WARNING!!!
Clear line of sight between the Radio Frequency equipment is
mandatory. This means that both antennas must be visible to
each other in order to achieve the distances advertised. If
installed with floors or walls between the antennas, distances will
be significantly reduced.
Basic RF and Data installation rules MUST be adhered to:
-
Common DC ground must be installed between all low
voltage power supplies. Isolate this ground to ensure NO
earth ground contact is made.
-
Supplied DC voltage must be from a well-filtered, approved
power supply. This power supply should meet all FCC and
UL requirements. AVOID REVERSE POLARITY!
-
No metal shrouding should place near or around the
antenna or the antenna base. Such shrouding will diminish
the antennas output and the advertised distances will be
affected.
-
Shielded wire with a drain wire should be used in all cases
with the drain wire only being connected at the power
supply end to earth ground.
-
Wiring methods should be completed in a manner consistent
with local electrical standards.
