Important Safety Instructions
operating equipment and save for future reference.
• Outdoor Antenna Grounding – The antenna and coaxial cable
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.
• Power Lines – An outside antenna system should not be located in
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-4-PAK is a high quality outdoor antenna system designed for use
with up to four Crestron® XM or SIRIUS® satellite radio tuners. The inclusion of an
SRD-SPL-4 Four-Way Amplified Splitter enables distribution of the antenna signal
to four separate tuners while allowing the antenna to be positioned up to 200 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 splitter are achieved using industry
standard RG-6 cable and F-type connectors (not supplied).
Four 3-foot 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 the splitter will enable longer output cable lengths of up to
200 feet each.
NOTE: Unused splitter outputs do not have to be terminated for proper operation.
A 20 dB power passing attenuator is also included for use in preventing overload of
the splitter input 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 antenna output and the most distant radio should not exceed 275 feet.

comply with specifications for CE marking and standards per EMC and
Radiocommunications Compliance Labelling.
• Mount the antenna outdoors with the supplied wall mount or pole mount
accessories. Installation indoors or behind windows is not recommended.
Windowpanes can have tinted coatings that can attenuate the signal. The
attenuation of these coatings can vary greatly as a function of temperature.
• Use the radio’s signal strength display as a guide to adjust the antenna for
peak satellite signal reception.
• This antenna kit is designed to drive up to 200 feet of RG-6 cable with no
signal loss. For longer cable runs, use in-line amplifier(s) SRD-AMP-1
(purchased separately) to boost the signal.
• Although this antenna can receive signals from terrestrial repeaters, it is
recommended to always use the satellite signals for primary reception at
fixed sites. The satellite signals are much more stable and are not affected
by many uncontrolled variables that can impact reception signal quality
greatly over time.

Azimuth Adjustments
Wall Mounting
Attach the wall mount assembly to a flat surface. Use the supplied screws to secure
the mount in the position desired (use of the included anchors requires 5/16” holes).
Attach the antenna to any pole (not larger than two inches in diameter) using the
U-bolt and saddle with supplied attaching hardware as shown in the following
figures.
U-Bolt
NOTE: For operation in close proximity to high power satellite radio terrestrial
repeaters, please use the supplied 20 dB attenuator on the input of the splitter to
avoid amplifier overload. Otherwise this attenuator is not required.

Hookup
After the antenna is mounted, refer to the diagram on page 2, connect cables, attach
the splitter, adjust the antenna position, and finalize the installation as follows:
1. Attach the RG-6 cable from the antenna to the splitter port labeled IN.
2. Attach an RG-6 cable from one of the OUT ports and route the cable to the
radio. (If the radio is located by the splitter, you can use the included
F-male splice).
NOTE: For best results in all configurations, use quad-shielded RG-6 cable
whenever possible.
3. Using the supplied 3-foot F-Female to SMB adapter cable, connect the
RG-6 coaxial cable from the antenna to the radio’s antenna input.
4. Adjust the azimuth and elevation pointing of the antenna for best reception
using the antenna signal strength menu in the radio. The antenna has a beam
width of ± 25º, which is narrower than standard consumer-quality home-kit
antennas, but provides higher gain and rejection to multi-path interference.
The “Appendix”, which starts on page 10, lists exact magnetic azimuth
bearings and elevation pointing angles for many major cities throughout the
US and Canada.
5. Tighten all hardware and seal the outdoor connectors using the included
weather boot or other means to prevent moisture ingress.
Refer to the documentation supplied with the tuner/radio for information on
observing signal strength. Adjust the antenna as required to maximize the signal.
XM Reception
XM has two satellites located in fixed orbital positions in the southern sky (at 115°
W longitude and 85º W longitude). These satellites each carry all of the XM
channels, so it is only required to have an un-obscured line-of-sight to one of these
orbital locations.
Initially set up the antenna with its orientation approximately due south, at an up
elevation angle of approximately 45º. Use this as the starting spot and peak the signal
reception for maximum on one of the XM satellites using the antenna alignment
menu in the radio. The “Appendix” lists exact magnetic azimuth bearings and
elevation pointing angles for many major cities throughout the US and Canada.
SIRIUS Reception
SIRIUS has three satellites in elliptical orbits that are constantly moving over the
earth in a “figure 8”. These orbits are arranged so that two satellites are always in
view at any point in time at relatively high elevation angles (from + 45° to almost
90°) in the sky. Your antenna should be aimed at the “cross-over point” of the
“figure 8”, or about 96.5° West Longitude and 46° North Latitude.
The table and figure below provide relative azimuth pointing guidelines for the
United States and Canada. Your antenna should be aimed for the “X” in the figure.
The “Appendix” lists exact magnetic azimuth bearings and elevation pointing angles
for many major cities throughout the US and Canada. Since the satellites’ positions
are constantly changing, signal strength will vary somewhat at different times of the
day.

be < 1 VAC. If AC voltage is
found, check for ground loops.
Ensure proper cable type and
length(s) per the illustration on
page 2.
Ensure amplifiers are oriented
properly with the output
(marked with an arrow labeled
Radio) oriented towards the
radio.
Refer to the instructions
supplied with the antenna to
ensure the antenna is pointed
accurately.
Ensure that the tuner card is
registered/activated.
