Do I need external antennas?
In most cases, external antennas are not needed with the FX4200. The integrated internal antennas provide an average 4 dBi peak gain across all frequency ranges. If you are getting 3-5 bars signal strength, external antennas are most likely not necessary to improve performance. In fact, adding the wrong external antennas (less than 4 dBi, including cable loss) could decrease your router’s performance.
Situations where external antennas are needed are rare, and may include:
- Poor signal quality
- Challenging location (basement, thick building walls, scenarios where there is a strong 5G signal outside, but only 4G inside, etc.)
- The need to boost higher frequency bands
When using external antennas, consider the reliability of the manufacturer, correct connectors, bands/frequencies, and cable loss.
