DVB-T Outdoor Antenna AHD
Installation Guide

WARNING AND CAUTIONS:

• TO AVOID FIRE, SHOCK, OR DEATH; TURN OFF POWER AT THE CIRCUIT BREAKER OR FUSE AND TEST THAT POWER IS OFF BEFORE WIRING!
• To be installed and/or used in accordance with appropriate electrical codes and regulations.
• Mounting: It is critical to the performance of this device that the antenna be oriented vertically. The antenna must point straight up or down for the proper operation. Straight up is preferred.
• If you are unsure about any part of these instructions, consult Synapse Customer Support. (877-982-7888)

DESCRIPTION

The Outdoor Antenna Kit helps ensure the best RF signal on sites with physical obstructions between the SimplySNAP gateway and other SNAP nodes such as lighting controllers, repeaters, and IIOT SimplySNAP products.

CAUTION

• The outdoor antenna must be installed in accordance with national, state, and local electrical codes and requirements
• All work must be performed by qualified personnel
• Disconnect all power before installation or service

INSTALLATION INSTRUCTIONS

Note: The RP-SMA bulkhead is permanently attached to the Type N connector and the bracket. The reason for the permanent
connection is to meet FCC requirements. Any attempt to disassemble will void the warranty and violate FCC regulations.

1. After installing the SimplySNAP gateway, determine where the outdoor antenna will be mounted.

2. Using the built-in mounting bracket, mark the mounting holes on the antenna bracket on the mounting surface. Use proper screws and anchors to attach the bracket to the mounting surface.
   Note: In order to ensure the best RF transmission, please ensure that the antenna is mounted in a vertical alignment.

3. Attach the RP-SMA Adapter (Figure 2) to one end of the cable and then attach the 50 Ohm terminator (Figure 3) to the RP-SMA
   Adapter. (This is the end that will attach to the antenna.)
   Note: The 50 Ohm terminator and RP-SMA adapter help discharge any built- up static from the coax cable during installation. The static can damage the SNAP RF Module which will create poor RF connectivity. The 50 Ohm Terminator and the Female RP-SMA adaptor will be used for installing the cable and will not be part of the final assembly. It is the installer’s responsibility to protect the Gateway’s RF module from high static charges.|

4. (If the installation requires passing through a wall.) Drill a hole with a 3/8” drill bit. Use 50 Ohm terminator end of the cable to thread the cable through the wall while leaving enough cable to connect to the Gateway or Repeater.

5. Attach the Cable to the Gateway
   Touch your hand to the metal case to discharge any built-up static charge then connect the loose end of the cable (the end without the 50 Ohm terminator) to the SNAP bulkhead connector on the gateway. Hand tighten the cable and then use a pair of needle-nose pliers to tighten the cable jack  1/4 turn. If a torque wrench is available, tighten the cable to 10-inch pounds.
   Note: Do not overtighten or you can damage the internal pin of the cable jack. Damage to the internal pin will cause poor RF connectivity.
   Note: SimplySNAP Gateways are not rated to be mounted outdoors without being placed inside a 4X Rated NEMA Box.
   The Central Base Station is rated for outdoors.

6. Attach the cable to the Antenna
   Touch your hand to the mounting bracket to discharge any built-up static charge. Remove the 50 Ohm terminator from the Female RP-SMA. Remove the Female RP-SMA adaptor from the Cable. Retain these parts for future cable installations.
   Attach the end of the cable to the antenna. Hand tighten the cable and then use a pair of needle-nose pliers to tighten the cable jack 1/4 turn. If a torque wrench is available, tighten the cable to 10-inch pounds.
   Notes:
   • Do not overtighten or you can damage the internal pin of the cable jack. Damage to the internal pin will cause poor RF connectivity.
   • Do not substitute cables. Synapse uses 50 Ohm RF cables that are double- shielded, low-loss, and flexible. The double-shielding is a major factor in the higher quality of this cable, which translates into lower loss/better performance.
   • When routing the RF cable do not create hard ninety-degree turns. Instead, use a gentle turn to prevent damage to the RF cable.
   • Be sure to create a drip loop in the coax cable to prevent water from ingressing into the device. The drip loop needs to be lower than the connection to the device and the antenna.
   

7. Secure the cable and Strain Relief
   It is important to avoid any sharp turns or kinks in the cable. Avoid pinching the cable or smashing the cable flat. Leave enough slack so the cable does not have tension on the connection to the SimplySNAP Gateway’s bulkhead or the connection to the antenna bulkhead. Using straps or cable ties,  secure the cable to provide strain relief and keep the cable secure. It is important to keep any unnecessary pressure or strain of the cable connections.
