Note: Before you start drilling holes or permanently attaching the MegFi to the vehicle, make sure the
cables from the antenna will reach from the mounting point of the antenna to the location of the
installed MegaFi, leaving enough cable length for stress relief before connecting to the SMA
connectors. See more information below in the section ‘Connect Antenna Cables to MegaFi’.
Mount the Antenna on the Roof:
1) Select a location for the antenna. For best performance it is highly recommended to locate the
antenna:
A. At least 30” from all other antennas
B. Within 15’ of where you will mount the MegaFi unit, so the connection cables can reach
the MegaFi unit in the vehicle
C. At least 12” from the edge of the roof
D. 20” or more from vehicle occupants per FCC rules for use of the MegaFi
2) Mount the antenna per the antenna manufacture

they may be different.
To Mount the Antenna:
Note: You can find installation instructions for the Parsec Australian Shepard antenna at www.parsec-

A. Drill a hole in the roof or other suitable flat, horizontal to the earth surface, of the
vehicle.
B. Gently place the antenna on the roof and feed the cables through the hole. To fully seat
the antenna on the roof, peel the backing to expose the adhesive and press the antenna
firmly into place.
Install the SHIELD MegaFi Unit Inside the Vehicle:
1) Place the unit on a suitable flat surface within the vehicle leaving clearance for cable and power
connections. The location should be dry and as far away from openings as is reasonable and be
within easy reach of the antenna cables.
Note: Leave at least a 2-inch space (air gap) open above the MegaFi to ensure proper cooling, and
never place any other devices directly on the MegaFi.
2) Secure the unit with four screws appropriate for the material the MegaFi is being mounted on.
Connect Antenna Cables to MegaFi:
1) Each antenna cable is appropriately labeled. Connect each cable to its designated connector on
the MegaFi device.
Note: SMA connectors have a maximum torque of 3-5 inch lbs. Over-torquing may damage the
connectors and void warranty.
