Here are the key differences between the 1dB and 5dB external antennas:
Gain – The 5dB antenna has higher gain, meaning it can focus the wireless signal in a narrower beam for increased range. The 1dB antenna has lower gain.
Directivity – The 5dB antenna’s radiation pattern is more focused and directional due to its higher gain. The 1dB antenna is less directive with a wider beamwidth.
Range – The higher gain 5dB antenna can achieve longer transmission distances. The lower gain 1dB antenna has a shorter effective range.
Coverage Pattern – The 1dB antenna provides a broader, multi-directional coverage area. The 5dB antenna’s coverage is more concentrated in a single direction.
Size – The 5dB antenna is physically larger to accommodate the larger reflectors/directors needed to produce the increased gain. The 1dB antenna is more compact.
In summary, the 5dB high-gain antenna is better for long range point-to-point links, while the 1dB antenna is preferable for broader short-range coverage. The choice depends on your specific wireless range and coverage requirements.
