Installation Guide - External Antenna

Step 1

1.1 - Mount & install 2x High-Gain Antennas on the external roof (preferred) or wall of the building.
1.2 - Ensure that the antennas are kept a minimum of 300mm apart from one another, with a minimum of 5 meters apart from any other pre-existing communications equipment, & that they are not covered or obstructed by any metal, brick or concrete walls, ceilings, poles or structures.
1.3 - Run a length of Coaxial Antenna Cabling from each external antenna’s mounted position, back to the Damstra Terminal inside the building.  (Avoid using any excess of cabling length, as this may affect signal quality).
1.4 - Terminate each end of the cabling with the appropriate SMA Connectors to suit.

Step 2

2.1 - Unscrew the existing standard antennas from each external side of the Damstra Terminal cabinet  (white).
2.2 - Connect each of the new High-Gain Antenna cabling runs to each side of the Damstra Terminal  (purple).
(When correctly installing 2x High-Gain Antennas per Terminal, the orientation of the left / right side is not important).

Step 3

3.1 - Unlock & open the Damstra Terminal cabinet door. Locate the Modem (highlighted in yellow), & ensure that all internal & external connections (highlighted in purple) are connected properly & are tight. 

3.2 - Locate the power adapter for the Modem, & switch off / or disconnect it from mains power.

3.3 - Wait 5 minutes, then reconnect the Modem power adapter to mains power.

3.4 - Close & lock the Damstra Terminal cabinet door & allow up to 15 minutes for the Modem to automatically assess the available signal strength & establish a cellular connection.

3.5 - (Please store any removed or un-used modem & antenna equipment inside the Damstra Terminal cabinet)

Notes
Damstra Terminals using externally mounted antennas should always be connected to two individual High-Gain Antennas, to maintain a strong cellular connection.
In the event that one of these becomes damaged, or is unavailable, it is possible (but is not recommended) to attempt a network connection for a Damstra Terminal using only one External Antenna & one standard antenna (depending on the cellular signal quality available in the area).

To do this, the High-Gain Antenna must be connected to the “MAIN” or “CELLULAR” connector on the modem.
While the smaller standard antenna must be connected to the “RxDIV” or “DIVERSITY” connector on the modem.

Notes Continued
To determine which connector to use in this particular situation, please trace the internal Coaxial Cabling from the SMA Bulkhead Adapter (mounted through the top/sides of the Terminal cabinet), back down to the connectors on the modem.
(pictured above, & also in Step 3).

Yellow  =  Modem.
Purple  =  SMA Connections.
Green  =  The primary  MAIN / CELLULAR  Connector.
Blue  =  The secondary  RxDIV / DIVERSITY  Connector.

Modem Status Indicators are highlighted in Orange in the image above.
The LED lights which are shown here will display the current status of the cellular network.

No LED lights  =  No power to Modem, or Modem is rebooting, please wait.

STS / NET:  Solid or Flashing Green  -  Network Connecting / or is Connected.
STS / NET:  Flashing Orange or Red  -  Poor Signal or Not Connected, please wait.

Signal / Network:  Solid or Flashing Green  =  Network Connecting / or is Connected.
Signal / Network:  Flashing Orange or Red  =  Poor Signal or Not Connected, please wait.

If connection issues persist after completing the above, please:

1. Confirm that a good 4G Cellular Signal is available in the area where the Damstra Terminals & External Antennas are installed.
2. Check all SMA connections & cables are connected properly & are free from any damage.
3. Ensure that the antennas are kept a minimum of 300mm apart from one another, with a minimum of 5 meters apart from any other pre-existing communications equipment, & that they are not covered or obstructed by any metal, brick or concrete walls, ceilings, poles or structures.
4. Avoid using any excess cabling length, as this may affect signal quality.
5. Power off the modem for 5 minutes.
6. Power the modem back on, & allow up to 15 minutes for the Modem to automatically assess the available signal strength & establish a cellular connection.
7. Contact Damstra Technology – Service Delivery Team at [e-mail]  or  1300 722 801.

Please include the Site Name, the location of the Terminal, the Terminal’s Serial / Identification Number, and any relevant information about the issue.
