Product Introduction
Precise Frequency Band Optimization for Clear and Stable Signal: Designed specifically for the 240-250MHz frequency band, ensuring maximum signal transmission efficiency within this range. Combined with a voltage standing wave ratio (VSWR) as low as below 1.5, it effectively reduces signal energy loss, guaranteeing clear and stable calls without noise interference.
Standard Interface for Plug and Play: Equipped with a universal BNC connector, installation is simple and highly compatible. No tools are required to quickly replace or upgrade your walkie-talkie's original antenna, achieving a convenient "plug and play" experience.
Rugged and Durable Construction: Made with high-quality materials, while not emphasizing "ultra-softness," it possesses good mechanical strength and toughness, able to withstand wear, impacts, and bending during daily use, ensuring long-term stable operation in various working environments.
Lightweight Design for Unobtrusive Communication: Weighing only 20 grams and with a compact 75mm length, it enhances signal strength while adding almost no extra weight or size to the walkie-talkie, providing users with a flexible and unobtrusive holding and carrying experience.
A Perfect Balance of Performance and Size: A gain of 2dBi achieves an excellent performance balance within a compact antenna size, effectively improving communication range and signal reception sensitivity while avoiding the inconvenience of excessively long antennas in complex environments.
Application Scenarios
Factory Workshops and Production Line Scheduling: In noisy industrial environments, a stable signal ensures clear and accurate communication between managers and employees at each workstation. The compact design prevents snagging when moving between equipment.
Shopping Malls and Retail Operations: Security guards and floor managers rely on reliable communication for daily patrols and coordination. This antenna provides clear voice quality and is lightweight and unobtrusive.
Campus and Property Security Management: Security teams need communication for patrols within fixed areas. Its universal compatibility facilitates centralized procurement and replacement, and its durability reduces long-term operating costs.
Construction Site Collaboration: Foremen and construction workers in dusty, bumpy construction environments require robust and durable communication equipment. This antenna can withstand harsh physical conditions.
FAQ
Q: My walkie-talkie has a BNC interface, but the frequency is 220-230MHz. Can I use it?
A: It is not recommended. The GL240B10 is optimized for the 240-250MHz frequency band. Using it on non-nominal bands will result in a significant performance degradation, such as signal weakness and increased VSWR, which may affect the walkie-talkie. Please choose an antenna that matches the frequency of your device.
Q: What is the difference between this antenna and the GL240B9?
A: The main difference is in physical size and weight. The GL240B10 is 75mm long and weighs 20g, while the GL240B9 is 95mm long and weighs 18g. Electrical performance (such as frequency, VSWR, gain) and interface are exactly the same. You can choose according to your preference for length and weight.
Q: What does 2dBi gain mean for an antenna? Is it sufficient?
A: dBi is a unit that measures the directivity of an antenna. 2 dBi is a standard and practical value for handheld antennas, striking a good balance between omnidirectional coverage and signal enhancement, making it ideal for most short- to medium-range handheld walkie-talkie communication scenarios.
Q: Is installing this antenna complicated?
A: Very simple. BNC is a quick-connect interface. Simply align the pin at the bottom of the antenna with the groove on the walkie-talkie interface, gently insert it, and rotate it clockwise about a quarter turn until you hear a "click," indicating it's properly installed.
Q: Is this antenna waterproof?
A: The product documentation does not explicitly state the waterproof rating. Therefore, it is suitable for general outdoor use (such as light rain), but prolonged immersion in water or use in heavy rain is not recommended. For high-strength waterproofing, look for antenna products with a clearly stated IP rating (such as IP67).
Q: Its V.S.W.R. value is <1.5. What are the benefits of this?
A: V.S.W.R (Voltage Standing Wave Ratio) is a metric that measures the efficiency of energy transfer between an antenna and a walkie-talkie. The lower the value (ideally 1), the higher the efficiency. An excellent value of <1.5 means that the energy emitted from the walkie-talkie can be more effectively converted into radio waves by the antenna, resulting in a longer communication distance and a clearer signal.
