Frequently Asked Questions
Q: What devices are compatible with these 2.4G/5.8G dual-band PCB antennas?
A: These dual-band antennas are compatible with any device that uses a standard MMCX connector and operates in the 2.4 GHz (2400–2500 MHz) or 5 GHz/5.8 GHz (4900–5900 MHz) frequency bands — including WiFi routers, drones, IoT modules, embedded development boards, and wireless communication systems with a 50-ohm RF input.
Q: Can the cable length or connector type be customized?
A: Yes! The standard cable length is 15 cm, but custom lengths and alternative connector types are available. Please reach out to us directly before placing a bulk or custom order and we'll be happy to accommodate your requirements.
Q: What is the difference between 2.4G and 5.8G, and which should I use?
A: The 2.4 GHz band offers wider range with slightly lower data throughput, while the 5.8 GHz band provides faster speeds over shorter distances with less interference. These dual-band PCB antennas support both simultaneously, making them versatile for routers and devices that switch between bands automatically or require dedicated coverage on each frequency.
Q: Are these antennas ready to use right out of the box?
A: Yes — no assembly is required. Simply connect the MMCX plug to your compatible device and the antenna is ready for use immediately.
