Bat Wireless BFGSMJWX105X7KJ is a high-performance omnidirectional antenna with excellent penetration capability, ultra-long communication distance, strong environmental adaptability, small size and light weight. It adopts a high-quality plastic shell, with a non-foldable Straight head, and has excellent signal receiving and transmitting capabilities, providing stable and reliable support for device connection. Its compact and lightweight rubber rod design makes it easy to install, transport and carry.

Core Product Features: Dual Optimization of Portability and Performance

1. Electrical Characteristics: Wideband Coverage for All GSM Standards, Stable Signal with No Blind Spots

• Full GSM Band Compatibility：Operating frequency range of 800-2200MHz, precisely covering core global GSM communication bands (850MHz/900MHz/1800MHz/1900MHz). It supports 2G GSM, EDGE, and other communication standards, eliminating the need for antenna replacement due to regional (e.g., 900MHz in Europe, 850MHz in North America) or operator differences. It is compatible with GSM mobile phones, wireless data modules, SMS alarms, and other GSM devices.
• 360° Omnidirectional Radiation (No Blind Spots)：Adopts a 360º omnidirectional radiation structure, allowing signals to spread evenly in the horizontal direction. Unlike directional antennas (which require alignment with base stations), it can capture weak GSM signals in complex environments (e.g., urban buildings, suburban villages), making it especially suitable for scenarios where device positions change flexibly (e.g., handheld terminals, mobile monitoring equipment).
• Low VSWR for Efficient Transmission：Voltage Standing Wave Ratio (VSWR) ≤1.8 (typical value for GSM bands), highly matching the 50Ω impedance of most GSM devices to reduce signal reflection loss. Equipped with an SMA Male Jack (Inner Thread, Inner Pin), the connector enables smooth plugging and tight mating (fitting tolerance ≤0.03mm), avoiding GSM call disconnection and data transmission packet loss caused by poor contact, ensuring long-term stable communication.

2. Mechanical Characteristics: Foldable Rubber Structure, Balancing Portability and Durability

• Foldable Design Saves Space：Features a foldable structure—105mm when unfolded, only 52mm when folded (about half the length of a finger), which can be easily stored in device casings, pockets, or backpacks. It perfectly solves the problem of "occupying space and being inconvenient to carry" of traditional fixed antennas, compatible with space-sensitive devices such as mini GSM phones, portable locators, and handheld emergency terminals.
• Durable Rubber Material：The antenna body is made of anti-aging nitrile rubber (Shore hardness 50±5), with excellent bending and impact resistance: it can withstand ≥1000 times of 180° folding (folding life test standard), and will not crack after daily drops (1.5m drop to concrete ground) or extrusion (50N pressure). The smooth surface is easy to clean—dust and oil stains can be wiped directly, making it suitable for outdoor or industrial harsh environments.
• Mini Size & Lightweight：Overall dimensions are only 105mm×7mm (7mm in diameter, about the thickness of a pencil), weighing only 8g (about the weight of 2 paper clips). It has no obvious weight feeling when installed on devices; the antenna base is equipped with an anti-slip gasket, which is not easy to loosen when fixed to the device interface, even if the handheld device shakes violently (e.g., during outdoor work).

3. Environmental Characteristics: Compliant & Weather-Resistant, Adaptable to Multi-Scenario Conditions

• Dual International Environmental Certifications：Strictly complies with RoHS & REACH regulations, containing no harmful substances such as lead, cadmium, or phthalates. Whether for home use (children’s GPS watches), commercial use (mall SMS alarms), or industrial use (workshop GSM data modules), it meets global environmental requirements, avoiding procurement restrictions due to non-compliance.
• Wide-Temperature & Weather-Resistant Design：The rubber material and internal circuit are optimized to adapt to an operating temperature range of -20~+60℃, enabling stable operation in extreme environments such as outdoor winter in northern regions (-15℃) and summer inside cars in southern regions (+55℃). The rubber shell has a certain degree of water resistance (IP54 dustproof and waterproof, non-immersion scenarios), so no additional protection is required for outdoor use in rainy days, extending the service life of the device.

Core Advantages: Four Differentiated Values for GSM Scenarios

• "Foldable + Mini" for Ultimate Portability：The size is halved when folded, weighing only 8g, compatible with various handheld or portable GSM devices. It solves the pain point of "needing to carry an antenna along with the device", especially suitable for mobile scenarios such as outdoor work and emergency communication.
• "Rubber + Durable" for Harsh Environments：Nitrile rubber is more resistant to bending and dropping than plastic antennas, reducing the damage rate of antennas in outdoor or industrial scenarios and lowering later replacement costs.
• "Full Band + Omnidirectional" for Global Use：800-2200MHz covers global GSM bands, and omnidirectional radiation enables flexible signal capture. No customized antennas are required for different regions, making it suitable for cross-border device procurement or globally deployed projects (e.g., international rescue equipment, cross-border logistics locators).
• "Plug-and-Play" for Zero Installation Threshold：The SMA male jack can be directly inserted into the device’s SMA female socket for use, no tools or professional operations are needed. Even individual users (e.g., vintage GSM mobile phone enthusiasts) can easily replace it, compatible with DIY devices or emergency replacement scenarios.

Multi-Industry Application Scenarios: Covering Core GSM Communication Needs

• Portable Communication Devices: Mini GSM Phones & Emergency Terminals：Compatible with vintage GSM feature phones and outdoor emergency phones. It can be stored in the side groove of the phone body when folded, and enhances signal reception when unfolded. In weak signal areas (e.g., mountains, basements), the antenna angle can be adjusted (fixed at 30°/90°/180° after folding) to capture stronger GSM signals, ensuring emergency calls or SMS sending (e.g., dialing 112 during outdoor rescue).
• Industrial IoT: GSM Data Modules & Monitoring Equipment：Installed on industrial GSM data transmission modules (e.g., remote meter reading modules, equipment fault alarms), the foldable structure can be embedded in the narrow casing of the device, and the rubber material resists oil and dust in the workshop. 360° omnidirectional radiation ensures that the module can stably send GSM data (e.g., electricity meter readings, fault codes) even in the corner of the workshop (far from windows), without additional wiring or adjusting the device position.
• Vehicle & Mobile Scenarios: On-Board GSM Terminals & Locators：Compatible with on-board GSM locators and truck SMS alarms. The antenna is fixed inside the device when folded, not occupying in-car space; the rubber material is anti-vibration (meeting the vibration standard for on-board electronics: 10-500Hz, 1.5g acceleration), and will not loosen or damage due to vehicle bumps during driving, ensuring real-time upload of GSM positioning data to the platform.
• Outdoor Emergency: Handheld Walkie-Talkies & Rescue Equipment：Used for outdoor GSM emergency walkie-talkies and wilderness survival terminals. It can be placed in a first-aid kit or pocket when folded, and can be used as a "signal booster rod" when unfolded. The rubber material is waterproof and drop-resistant, so no damage is needed in rainy days or climbing. In remote areas without 4G/5G signals, positioning information or distress SMS can be sent via the GSM network to ensure personnel safety.
• Consumer Electronics: GSM Locators & Smart Wearables：Compatible with children’s GSM GPS watches and elderly anti-lost terminals. The mini size and foldable structure can be embedded in the watch strap or terminal casing, without affecting wearing comfort. The rubber material is soft and skin-friendly, with no irritation for long-term skin contact, and is resistant to children’s biting (no harmful substances leach from the surface), balancing safety and practicality.
