MikroTik SXT SQ Lite devices are CPEs (Customer Premises Equipment) designed to be used in outdoor wireless networks, especially in point-to-multipoint configurations.

When it comes to connecting these devices to an OmniTIK, a MikroTik omni-directional access point designed for the same purpose, the ideal distance can vary depending on several factors including the physical environment, line of sight, interference from RF and device-specific configuration.

The MikroTik SXT SQ Lite is designed primarily for short to medium distances, with an optimal range that may vary:

• In ideal conditions: With no significant obstructions, low interference and clear line of sight, the SXT SQ Lite can effectively connect to an OmniTIK at distances of up to 5-7 kilometers. It is important to note that these ideal conditions are rarely found in real environments.
• In real environments: The effective distance may be considerably less. Factors such as buildings, trees, and other forms of interference can significantly reduce the effective range of the connection. In densely populated urban or suburban environments, I would expect the effective range to be reduced to a few kilometers or even less.

To maximize the distance and quality of the connection between an SXT SQ Lite and an OmniTIK:

1. Ensures a clear line of sight: The presence of physical obstacles can block or degrade the RF signal.
2. Minimizes interference: Use tools like MikroTik's “Spectral Scan” to identify and avoid channels with high interference.
3. Precise alignment: Make sure the SXT SQ Lite and OmniTIK are properly aligned for optimal signal reception.
4. Proper setup: Properly configure both devices to optimize the signal, including adjusting transmit power, frequencies and channels.

MikroTik's official documentation and product specification sheets can provide further technical details and configuration recommendations.

However, for optimal results, field testing and fine-tuning based on the specific conditions and requirements of your environment is recommended.
