antenna models* for Point-to-MultiPoint mode:
AM-5AC21-60
AM-5AC22-45
AM-V5G-Ti
AM-M-V5G-Ti
AM-5G16-120

AM-5G17-90
AM-5G19-120
AM-5G20-90
AP-5AC-90-HD
* Requires Universal Bracket (included).
Installation Requirements
Clear line of sight between LTU™ AP and stations
Clear view of the sky for proper GPS operation
Vertical mounting orientation
Mounting point:
At least 1 m below the highest point on the structure
For tower installations, at least 3 m below the top of the tower
Ground wires – min. 10 AWG (5 mm ) and max. length: 1 m. As a safety
precaution, ground the LTU radio to a grounded mast, pole, tower, or grounding
bar.
WARNING: Failure to properly ground your LTU radio will void your
warranty.
Outdoor, shielded Category 6 (or above) cabling and shielded RJ45 connectors
are required for all wired Ethernet connections.
Surge protection should be used for all outdoor installations. We recommend
that you use two Ethernet Surge Protectors, model ETH-SP-G2, one near the
device and the other at the entry point to the building. The ETH-SP-G2 will
absorb power surges and safely discharge them into the ground.
Note: For guidelines about grounding and lightning protection, follow
your local electrical regulatory codes.

3.
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: http://192.168.1.20
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:
a. 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.
b. In the Security Key field, enter a combination of alphanumeric characters (0-
9, A-Z, or a-z).
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:
a. Click the icon.
