The **HG2407MGRD-RSP** is a high-performance, industrial-grade wireless antenna, specifically a **2.4 GHz Omni-directional Rubber Duck Antenna**. It is manufactured by L-com (a brand under Infinite Electronics). Below is a detailed breakdown of its electronic specifications and technical features. ### 1. General Specifications This antenna is designed for Wi-Fi and Bluetooth applications, providing a balance between physical flexibility and signal strength. | Feature | Specification | | :--- | :--- | | **Frequency Range** | 2400 - 2500 MHz (2.4 GHz Band) | | **Gain** | 7 dBi | | **Polarization** | Vertical | | **Input Impedance** | 50 Ohms | | **Max Input Power** | 50 Watts | | **VSWR** | < 2.0:1 | --- ### 2. Electronic Performance Characteristics #### A. Gain and Radiation Pattern * **7 dBi Gain:** This is considered high for a "Rubber Duck" style antenna. It provides a larger coverage area than standard 2 dBi or 5 dBi antennas by compressing the signal into a flatter "pancake" shape horizontally. * **Omni-directional:** It radiates signal 360 degrees around the vertical axis, making it ideal for central access points or mobile devices that move relative to the router. #### B. VSWR (Voltage Standing Wave Ratio) With a VSWR of less than **2.0:1**, the antenna ensures efficient power transfer from the radio to the air. A low VSWR minimizes "reflected power," which protects the transmitter's circuitry from overheating or damage. #### C. Connector Type: RP-SMA Plug The **RSP** in the model name stands for **Reverse Polarity SMA (RP-SMA) Plug**. * **Note:** This is the standard connector found on most consumer Wi-Fi routers (ASUS, TP-Link, Linksys). * **Design:** It features a female body with a male center pin (reverse of a standard SMA). --- ### 3. Physical & Material Composition The electronic components are housed in a ruggedized exterior to withstand industrial environments. * **Tilt and Swivel Feature:** The base includes a knuckle that allows the antenna to be oriented at 0°, 45°, or 90° angles, which helps in optimizing polarization based on the mounting position. * **Radome Material:** Typically constructed from UV-stable Polyurethane or TPE, protecting the internal copper radiating element from environmental degradation. --- ### 4. Typical Applications * IEEE 802.11b/g/n Wireless LAN (Wi-Fi) * Bluetooth and ZigBee systems * Public Wireless Hotspots * Multipoint and Mobile Applications ---
