Frequently Asked Questions
What does 9dBi mean on a WiFi antenna?
9dBi indicates the antenna gain which measures how much signal is focused in one direction. This helps extend range without increasing power consumption.
Will an antenna work with any router?
It depends on the connector. Most modern routers use RP-SMA so check your device port before buying to ensure compatibility.
Do tri band antennas need special hardware?
Yes you need a router or card supporting 6GHz for tri band to work fully. Otherwise it will function on dual band modes.
How do I install a magnetic base antenna?
Simply attach the base to a metal surface like your PC case or metal bracket. Ensure it is stable before connecting cables.
Are outdoor antennas better than indoor ones?
Outdoor antennas are weather resistant and durable which makes them better for exterior setups while indoor ones lack that protection.
Does a longer cable affect signal quality?
Very long cables can introduce slight signal loss but modern low loss cables minimize this effect for standard indoor setups.
Can I use multiple antennas on one router?
Yes if your router has multiple ports and supports MIMO using multiple antennas can improve speed and stability significantly.
