The **ANT-CAB-195-RPSMA-RPSMA-X** is a high-performance coaxial extension cable assembly commonly used in Wi-Fi and RF networking. The "195" refers to the cable type, while the connectors determine its compatibility with wireless equipment. --- ### 1. Technical Specifications Breakdown | Component | Specification | Description | | :--- | :--- | :--- | | **Cable Type** | LMR-195 Equivalent | Low-loss communication cable (0.195-inch diameter). | | **Connector A** | RP-SMA Male | Reverse Polarity SMA with internal threads and a hole. | | **Connector B** | RP-SMA Female | Reverse Polarity SMA with external threads and a pin. | | **Impedance** | 50 Ohms | Standard for RF and wireless data transmission. | | **Frequency Range** | 0 - 6 GHz | Supports 2.4GHz and 5GHz Wi-Fi bands. | | **Jacket Material** | PE or PVC | UV-resistant and durable for indoor/outdoor use. | --- ### 2. Key Electronic Characteristics #### A. Low Attenuation (Signal Loss) The "195" series cable is designed to provide lower signal loss than standard RG-58 cables. * **Performance:** At 2.4 GHz, the loss is approximately **19 dB per 100 feet**. * **Significance:** This ensures that the signal strength from the access point reaches the antenna with minimal degradation. #### B. Reverse Polarity SMA (RP-SMA) Unlike standard SMA connectors (used in GPS/Cellular), RP-SMA is the industry standard for Wi-Fi equipment (routers, antennas, and network cards). * **Male:** Features a knurled nut (internal threads) but has a **receptacle (hole)** instead of a pin. * **Female:** Features a barrel (external threads) but has a **center pin**. #### C. Shielding and Interference The cable utilizes double shielding (usually a combination of aluminum foil and a tinned copper braid). This provides: * **High RF Shielding:** Minimizes EMI (Electromagnetic Interference). * **Signal Integrity:** Maintains a clean data stream in environments with high wireless traffic. --- ### 3. Common Applications * **Antenna Relocation:** Moving a Wi-Fi antenna from the back of a server to a higher or clearer location to improve Line of Sight (LoS). * **Enclosure Patching:** Connecting an internal wireless module to an external bulkhead antenna on an industrial enclosure. * **Testing:** Extending the reach of RF measurement equipment in a lab setting.
