Your WiFi Turbo: More Power for 2.4 GHz and 5 GHz Antennas
No more weak signals! This WiFi Antennas is a significant upgrade for your home Network. While standard Antennas often stop at a meager 2-3 dBi, this model provides you with a solid 5 dBi in the highly frequented 2.4 GHz Antennas band and an impressive 7 dBi in the fast 5 GHz Antennas band. The result: a more stable connection, fewer dropouts during video calls, and potentially higher transmission rates, especially in the fringe areas of your WiFi.
Perfect for Your Home – Focused Signal Strength
This WiFi Antennas was specifically developed for use on a single level. Its clever 360° horizontal radiation pattern evenly covers the entire room. At the same time, the very narrow vertical angle of just 12° bundles the energy exactly where you need it. This way, no power is wasted on the ceiling or floor. This makes it the ideal high-performance WiFi Antennas for single-story apartments or office floors.
Maximum Compatibility Thanks to RP-SMA Connector
Whether it's a WiFi Router, WiFi Access Point, or PC – the compatibility is huge. The widely used RP-SMA connector (Reverse Polarity) ensures that you can connect the Antenna to devices from many well-known manufacturers. It's the perfect Dual-Band Antennas RP-SMA for Gaming PC and supports all common WiFi standards from 802.11a to the modern 802.11ax (Wi-Fi 6). Simply screw it on and benefit from better reception.
Easy Installation, Immediate Effect
You don't have to be a Network technician to improve your WiFi. Installation is child's play: unscrew old antennas, screw on the new ChangHong Antennas, done. No software configuration is necessary. Thanks to the integrated swivel joint, you can flexibly align the Antenna – for optimal omni-directional coverage, it's best to position it vertically.

Frequently Asked Questions (FAQ)
Does this antenna fit my WiFi Router, for example a Fritz!Box?
Absolutely, as long as your WiFi Router has detachable antennas with an RP-SMA connector. You can tell if it does by checking if the connector on your router has a small opening in the middle, into which our antenna's pin will fit. It's best to take a quick look at your router's manual or simply unscrew an old antenna to be sure.
Will I really get more WiFi range with this antenna?
Definitely! With a gain of 5 dBi on 2.4 GHz and a strong 7 dBi on 5 GHz, it's a real upgrade from standard WiFi Antennas, which often only have 2-3 dBi. You'll notice a more stable connection and better coverage, especially in those corners where your WiFi has previously struggled.
Is this antenna also suitable for my multi-story house?
Unfortunately, it's not the best choice for that. The antenna strongly focuses the signal on a horizontal plane, which is great for a single floor. However, for good coverage across multiple stories, you'll need an antenna that also distributes the signal more effectively upwards and downwards.
What exactly does the 5 dBi and 7 dBi gain mean for me?
Simply put: dBi indicates how strongly the antenna concentrates your WiFi signal in one direction. The higher the value, the stronger the concentration and the further your signal will reach. The 7 dBi in the 5 GHz Antennas band is particularly clever, as this frequency band naturally has a slightly shorter range – the antenna compensates for this for you!
Do I need to configure anything on my router after screwing it on?
No, not at all! The antenna is a passive component. You simply unscrew your old antennas, attach the new ones, and align them vertically. Your Router will immediately utilize the stronger performance, without any additional settings.
Does the antenna also work to boost my Bluetooth signal?
Yes, it does! Bluetooth also operates in the 2.4 GHz Components band. If your Bluetooth adapter, for example on your PC expansion card, has a compatible RP-SMA connector, you can also improve its range and stability with this antenna.
