For example, the signal coverage range of Kinghelm's KH0WF-02-J3 Wi-Fi dipole antenna is not fixed but typically reaches up to several meters in an open environment. Several factors influence the signal coverage range of Kinghelm’s Wi-Fi antennas:

Antenna Gain: Gain measures the antenna's ability to amplify the signal, typically expressed in dBi. Higher gain usually results in a greater signal range and coverage area. The KH0WF-02-J3 antenna, with a 3dBi gain, offers medium-range performance in its category.

Frequency Band: Wi-Fi typically operates at 2.4GHz and 5GHz. The 2.4GHz band has a wider coverage range but slower speeds and more interference, while the 5GHz band offers faster speeds but shorter range and weaker penetration through obstacles. The KH0WF-02-J3 operates at 2.4GHz, providing a better coverage range.

Environmental Factors: In an open, unobstructed space, such as a large outdoor area, the signal range can extend to several tens of meters or more. In indoor environments with walls and obstacles, the signal will weaken due to reflection, refraction, and absorption, reducing coverage. Metal objects and electronic devices can also interfere with the signal, further impacting coverage.

Transmitter Power: The greater the transmitter power, the wider the coverage. However, there are regulatory limits on transmission power, such as the 100mW limit for home routers in China. The transmitter power used with Kinghelm’s antennas can affect the overall signal coverage.
