REPORT POLAR

The chart shows excellent impedance matching at 2.461 GHz, with a return loss of –32.86 dB, indicating extremely low signal reflection and efficient energy transfer. The Smith chart confirms a near-ideal 50-ohm impedance. This performance makes the antenna highly effective for operation within the 2.4 to 2.5 GHz ISM band, suitable for applications like Wi-Fi, Bluetooth, and ZigBee.

REPORT SWR

the antenna is optimally matched at 2.461 GHz, with an SWR of 1.047 and a return loss of –32.86 dB, indicating near-perfect impedance matching and negligible signal reflection. This performance confirms that the antenna is highly efficient within the 2.4 to 2.5 GHz band, making it ideal for high-frequency wireless applications such as Wi-Fi, Bluetooth, and ZigBee.

REPORT DELAY AND PHASE

The phase and group delay of the antenna at 2.461 GHz shows a phase of 141.0° and a group delay of 11.67 ns, indicating stable signal behavior and minimal distortion near the resonance frequency. These characteristics confirm strong temporal performance, making the antenna well-suited for time-sensitive RF applications within the 2.4–2.5 GHz band.

We have a dual-band version (2.4 & 5GHz) of this antenna.

Vandal prone environments demand tough equipment that will resist excessive force upon them: Commonly used in a host of WiFi applications in demanding environments: Vandal prone areas, outdoors and harsh weather condition locations.

Waterproof /weatherproof: Totally sealed IP65 casing prevents risk of water ingress. Includes rubber O-ring (black) that totally protects against ingress of water or dirt.

  • Mounts directly onto RP-SMA(female) connector of access point, bridge, USB WiFi adapter, or booster. See other magnetic bases that fit this antenna and have antenna cables with other types of connectors .
