Installation Overview

We recommend that you configure your LTU-Rocket radio before site installation. The following sections provide detailed installation instructions. Perform these instructions in the sequence given.

Connecting Power over Ethernet

WARNING: Use only the included adapter, model POE-24V-5X-HD. Failure to do so can damage the unit and void the product warranty.

LTU Configuration

Access the LTU Configuration Interface for configuration. By default, Access Point mode is already enabled for the LTU-Rocket. You can choose to configure settings such as Link Name, Duty Cycle, Channel Bandwidth, and Frequency.

The PTMP stations will scan and find the LTU-Rocket and do not need any frequency set as long as they are set with the same Channel Bandwidth and Link Name.

Configuration Using Browser-Based Interface

  1. Configure the Ethernet adapter on your computer with a static IP address on the 192.168.1.x subnet.
  2. Launch your web browser. In the address field, type:

    Then press enter (PC) or return (Mac).

  3. Select your Country and Language. You must agree to the Terms of Use, EULA, and Privacy Policy to use the product. Click Continue.
  4. Click the icon.
  5. Configure the following settings:
    1. If needed, change the Channel Bandwidth, Frequency, Output Power (EIRP), Antenna Gain, and Max TX Modulation settings. The Channel Bandwidth should be the same on all devices in the PtMP link.
    2. In the Security Key field, enter a combination of alphanumeric characters (0-9, A-Z, or a-z).
    3. Note: The key is an alphanumeric password between 8 and 63 characters long.

  6. Click Save Changes.
  7. Configure a unique IP address for the Data port:
    1. Click the icon.
    2. For the Data IP Address option:
      • DHCP Have your router use DHCP reservation to assign a unique IP Address.
      • Static Change the IP Address, Netmask, and other settings to make them compatible with your network.
    3. Click Save Changes.

Upgrade for IP67 Compliance

To protect the LTU-Rocket from intrusion by water, dust, and insects, we recommend installing the IP67 Upgrade Kit (included):

  1. Note: Do not damage or remove the post on the Port Cover.

Hardware Installation

Installing the Ground Wire

  1. At the installation site, secure the other end of the ground wire to a grounded mast, pole, tower, or grounding bar.
  2. WARNING: Failure to properly ground your LTU radio will void your warranty.

    Note: The ground wire should be as short as possible and no longer than one meter in length.

Mount to an airMAX Sector Antenna

The LTU-Rocket is designed to mount directly onto the Ubiquiti antennas listed in “Antenna Compatibility”. The airMAX Sector antenna AM-5AC21-60 is shown in this section:

Mount the External GPS Antenna

Locate a mounting point that has a clear view to the sky, and is above and as far away as possible from the LTU-Rocket.

  2. OR

Connecting Power over Ethernet

  2. OR

    Note: If the IP67 Upgrade Kit is installed, first apply dielectric grease to the cable connector and port.

  3. WARNING: The LTU-Rocket must receive a minimum of 15W. Ensure that the voltage range of the PoE source is within these limits:

    • 4-pair operation: 18-54V
    • 2-pair operation: 30-54V


    WARNING: Use only the included adapter, model POE-24V-5X-HD. Failure to do so can damage the unit and void the product warranty.


Installer Compliance Responsibility

Devices must be professionally installed and it is the professional installer’s responsibility to make sure the device is operated within local country regulatory requirements.


Select your antenna from the list. If Auto Output Power is enabled, transmit output power is automatically adjusted to comply with the regulations of the applicable country. For a Custom antenna, Antenna Gain is entered manually. Note the requirements and antenna types listed below.

Cable Loss (When applicable)

Enter the cable loss in dB. Output power is adjusted to compensate for loss between the radio and the antenna.

Certified Antenna Types

This radio transmitter FCC ID: SWX-LTUR / IC: 6545A-LTUR has been approved by FCC / ISED Canada to operate with the antenna types listed below with the maximum permissible gain for each antenna type indicated. Antenna types not included in this list or having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.
