Choose a mounting location. The SRA-25 antenna must be mounted
horizontally in a location that is open and has a clear view of the sky. It must be
mounted away from any metal objects or other structures that could block the
line-of-sight reception of the satellite signal. The height of the antenna is not as
important as having a clear view of the horizon. To determine the best location
for the SRA-25, hold the Satellite Shooter template (back page) horizontally at
the chosen mounting location and follow the instructions on the template. Scan a
full circle with the Shooter to make sure no obstacles block the antenna’s view of
the sky from overhead.
In choosing how and where to mount the antenna, consider the accessibility
of the area underneath, and whether the area is clear of any wires or other
obstructions. Choose a convenient pathway for running the coax cable as far as
possible from other electrical cables.
The SM-32 Surface Mounting Kit (if included, see note on next page)
requires a at, not curved surface. The antenna’s cable can be routed through a
hole in the mounting surface or through the Surface Mounting Kit.
IMPORTANT: When mounting to a at surface using the Surface
Mounting Kit, orient the Mount so that its cable exit faces the rear of the vessel
or vehicle, away from oncoming wind due to normal vessel or vehicle motion.
Mount the SRA-25 so that it does not interfere with safe operation of the vessel
or vehicle.
If the distance between the antenna and your Satellite receiver is more than
25 feet, special Shakespeare cable kits are available (see Optional Accessories,
back page). Acquire the appropriate kit and an SM-32 Surface Mounting Kit (if
needed and not included) before proceeding.
SURFACE MOUNTING
If you are attaching the antenna directly to a at surface, the cable with its
connector attached can be routed through a 9/16” hole drilled in the mounting
surface.
Do not cut the cable and do not remove the connector.
Step 1: Drill a 9/16” mounting hole. When drilling berglass surfaces, use a
small backup block of scrap wood to control push-through splintering. Use
caution to avoid drilling through or near fuel lines, fuel tanks, hydraulic lines, or
electrical wiring. For mounting surfaces from 1/4” to 1” thick, use the extension
shaft (supplied) - see illustration on next page.
· Route the 6” antenna lead with TNC female connector through the center
of the extension shaft.
· Thread the Extension Shaft onto the existing antenna shaft and tighten.
Step 2: Pass the connector, cable, and shaft (if used) from the SRA-25 through
the hole.
DO NOT CUT THE CABLE OR REMOVE THE CONNECTOR!
Step 3: Secure the antenna to the mounting surface with the supplied retaining nut
and lock washer (see Figures 2 & 3). A small bead of RTV around the outer edge of
the antenna base is recommended to insure a watertight seal.
Skip to “Completing the installation” on page 5.
SURFACE MOUNTING USING STYLE SM-32 MOUNTING KIT
NOTE: The Style SM-32 Surface Mounting Kit makes it possible to
mount the SRA-25 to a surface that has restricted or non-existent access
underneath. The SRA-25 is sold both with and without the SM-32 Kit
included. If your antenna does not have the SM-32, you must purchase it
separately, if needed.
If you are attaching the antenna/SM-32 assembly to a at surface, the cable
with its connector attached can be routed through a 9/16” hole drilled in the
mounting surface, or passed through the Mounting Base. Do not cut the cable and
do not remove the connector.
If you are running the cable through the mounting surface (Option a):
Step 1a: Drill a 9/16” center hole for the antenna cable. When drilling berglass
surfaces, use a small backup block of scrap wood to control push-through
splintering. Use caution to avoid drilling through or near fuel lines, fuel tanks,
hydraulic lines, or electrical wiring.
Step 2a: Attach the SRA-25 antenna to the Mounting Base using the washer and
nut as shown in the diagram at right). Use the assembly as a template to mark
locations for the mounting screws
Step 3a: Orient the gasket so as to block the cable exit notch, as illustrated on
page 4.
