Choose a mounting location. The SRA-40 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-40, 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.
The Mounting Flange requires a flat, not curved surface, or the antenna can be mounted on
the 1"-14 thread end of a marine antenna extension mast or a Shakespeare Style 4720 Rail Mount
(each sold separately). The antenna's cable can be routed through a hole in the mounting surface,
through the Mounting Flange, or through the extension mast.
IMPORTANT: When mounting to a flat surface using the mounting flange and gasket, orient
the Mounting Flange 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-40 so that it does not
interfere with safe operation of the vessel or vehicle.
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.
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 before proceeding.
If you are attaching the antenna directly to a flat surface, the cable with its connector attached
can be routed through a 9/16" hole drilled in the mounting surface.
Step 1: Drill a 9/16" mounting hole. For mounting surfaces from 1/4" to 1" thick, use the
extension shaft (supplied).
· 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-40 through the hole.
