connecting to the unit should be properly grounded to provide
protection against voltage surges and built-up static charges. Article
810 of the National Electrical Code (NEC), ANSI/NFPA 70, provides
information with regard to proper grounding of the mast and
supporting structure, grounding of the lead-in wire to an antenna
discharge unit, size of grounding conductors, location of antennadischarge unit, connection to grounding electrodes, and requirements
for the grounding electrode.
the vicinity of overhead power lines or electric light or power circuits,
or where they can fall into such power lines or circuits. When
installing an outside antenna system, extreme care should be taken to
keep from touching such power lines or circuits, as contact with them
might be fatal.

The SRD-ANT-8-PAK is a high quality outdoor antenna system designed for use
with up to eight Crestron® XM or SIRIUS® satellite radio tuners. The inclusion of
two SRD-SPL-4 Four-Way Amplified Splitters enables distribution of the antenna
signal to eight separate tuners while allowing the antenna to be positioned up to 310
feet (cable length) from the tuners, using standard RG-6 cable (not included).
The antenna features a considerably narrower beam width compared to standard
consumer antennas, achieving superior gain and multi-path rejection. Additional
front end filtering provides excellent rejection to nearby out-of-band RF signals from
sources such as Wi-Fi, cellular telephones, and cordless telephones.
A wall mount bracket with elevation and azimuth adjustments is provided for
installation of the antenna to any horizontal or vertical flat surface. The additional
U-bolt and saddle enable mounting to a pole (not included) up to two inches in
diameter. Connections between the antenna and splitters are achieved using industry
standard RG-6 cable and F-type connectors (not supplied).
Eight 3-foot long F-to-SMB adapter cables are included for connecting each tuner to
the splitter outputs. If needed, standard RG-6 cable with male F-connectors (not
supplied) may be used to extend the output cable lengths up to 70 feet from each
individual splitter output to the tuners. Adding an SRD-AMP-1 line amplifier (sold
separately) at the input of either splitter will enable longer output cable lengths of up
to 250 feet each.
The SRD-ANT-8-PAK utilizes an SRD-CPL-4 Four-way Coupler to split the
antenna signal to each of the two amplified splitters provided. The two unused
outputs on the coupler may be used to feed additional amplified splitters, allowing
easy expansion to support distribution of the antenna signal to a total of up to 16
satellite radio tuners.
NOTE: Unused splitter outputs do not have to be terminated for proper operation.
A 20 dB power passing attenuator is also included with each splitter for use in
preventing overload of the splitter inputs in any installation that is located near a
high-power satellite radio terrestrial repeater.
NOTE: In this typical layout example, the sum total of all the cable segments
between the line amplifier output and the most distant radio should not exceed 310
feet.
