# Installation
## Minimum Installation Setup
### 1. Connect WiFi and LTE antennas
Take SmartAP AIRLink Enterprise and connect WiFi and LTE antennas.
{% hint style="danger" %}
**WARNING**: DO NOT power the AIRLink without antennas! Powering up the system without antennas may cause malfunction of the radio modules and permanent damage. Powering up without antennas voids warranty.
{% endhint %}
Connect the WiFi antenna to the WiFi socket (middle) by gently pushing on the antenna connector:
AIRLink with WiFi antenna connected:
Connect LTE antennas to LTE1 and LTE2 sockets (sides):
{% hint style="warning" %}
If it is not necessary, do not remove the antennas from the connector. The connectors are quite fragile and are rated for only a limited number of matching cycles. Bad connection can result in reduced RF communication performance.
{% endhint %}
AIRLink 5G Edition has 5 antennas on the rear side - 1x WiFi and 4x 5G. It's recommended to connect all 4 antennas to achieve the highest possible throughput:
{% hint style="info" %}
If you have 4G LTE version of AIRLink with 5 antenna sockets then use only two leftmost LTE1 and LTE2 ports for LTE antennas.
{% endhint %}
### 2. Connect FPV camera
Camera connection is not necessary but recommended. This will allow you to test your setup and video streaming after the initial software setup described in the following sections.
First of all, take something sharp and unlock the CSI camera port connector by pulling it a bit at each side:
Then insert the FPC cable from the camera and gently push back the black part of the connector mechanism until it locks itself tightly:
Repeat the same procedure with the camera socket. Once done you should have the camera connected to AIRLink.
### 3. Connect power supply
Take the main power supply cable and connect this to the power source.
{% hint style="info" %}
We recommend to use [SmartAP PDB](/avionics/legacy-autopilots/pro.md) for the power distribution. It has a current sensor and DC-DC converters for 5V and 12V to power [SmartAP AIRLink](https://sky-drones.com/airlink) and other peripherals.
{% endhint %}
* Connect power cable to 12V output of [SmartAP PDB](/avionics/smartap-pdb.md).
* Connect power monitor cable (voltage and current) to the dedicated pins on [SmartAP PDB](/avionics/smartap-pdb.md).
{% hint style="danger" %}
**DANGER:** Make sure to connect the cable with the right polarity. Reversing polarity may damage the equipment permanently and will void warranty.
The recommended power supply voltage is 12V. The acceptable input voltage limits are 10V - 20V.
{% endhint %}
Next, connect the power cable to [AIRLink](https://sky-drones.com/airlink) as shown on the image below:
{% hint style="info" %}
Minimum installation setup is complete. If you would like to test the system you can refer to the next section and power it up for the initial configuration. If you would like to connect the other peripherals, please refer to the Full Installation Setup below.
{% endhint %}
Proceed to the initial power up or set up the other peripherals.
{% hint style="warning" %}
It's recommended to start with the Minimum Installation Setup for the very first power up.
