Performance and Reliability

With an impedance of 50Ω, the Kinghelm KH-04-SMAJ-H190 is designed to deliver high efficiency and minimal signal loss. The antenna exhibits a Standing Wave Ratio (S.W.R.) of ≤3.0 in the 700-960MHz range and ≤2.5 in the 1710-2690MHz range, indicating a high level of impedance matching and efficiency. The antenna gain of 1.0dBi ± 0.5 at 700-960MHz and 2.0dBi ± 0.5 at 1710-2690MHz ensures that the antenna provides a suitable boost to signal strength across these bands.

Design and Construction

The vertical polarization of the Kinghelm 4G Antenna KH-04-SMAJ-H190 ensures that it is well-suited to the typical signal propagation characteristics of modern wireless networks. The return loss of -6.0dB MAX at 1710-2690MHz highlights the antenna's ability to minimize the reflection of signals and maximize transmission efficiency.

Constructed with an RG178 RF cable, the antenna features a transparent brown cable that is both durable and flexible. The SMA male connector ensures a secure and stable connection to various devices, further enhancing the reliability of the antenna's performance.

Versatility and Applications

The black exterior of the antenna not only provides a sleek and professional appearance but also ensures that the antenna is unobtrusive in various installation environments. With an operating temperature range of -40°C to 85°C and a storage temperature range of -40°C to 80°C, this antenna is built to withstand harsh environmental conditions, making it suitable for both indoor and outdoor applications.
