Our Picks for Best 2.4 GHz and 5 GHz Antennas for WiFi Dual Band 2015

Top Selling Router 2.4 GHz and 5 GHz Dual Band Antennas for WiFi

Does your router have dead WiFi spots or lack in distance? Then buying a better antenna can boost signal quality and is a cheap and easy solution. Antennas can also be used with WiFi adapters that have a screw on antenna.
 
Most routers using a stock antenna have a range up to 300 feet. The same router with a external parabolic antenna in theory can go up to 20 miles.
 
The bowl shape of the parabola would have to be tuned to line of site and no obstructions in the way.
 
Of course this is what a good antenna and signal can do in theory. In real life getting 20 miles from a router is all but impossible, but increasing a routers WiFi distance can be done.
 
 
WiFi Antenna Basics
Antennas are rated by dBi with a lager dBi number being a larger antenna.
 
Small antenna that come with a router(usually 3-5 dBi) are good up close since the WiFi signal wave has not expanded yet.
 
As a radio wave travels away from its source the wave expands from its low peak to high peak.
 
To get a good signal an antenna must be large enough to capture both the high and low peak as it moves.
 
 
Will a Larger dBi Antenna Help You?
If you are looking to increase distance than yes a larger dBi antenna will help.
 
A larger antenna will not help with obstructions such as walls or trees.
 
To get a better signal past obstructions WiFi boosters are a better option or a router with a high gain.
 
 
Things To Check First
Many routers have a signal booster setting that can be increased. This can be checked by logging into the router and looking for a power increase setting.
 
Repositioning a router higher up and adjusting the antenna can also help in some cases.
 
 
Router Antenna Connector Types
The most common connector is called Male SMA followed by Male TNC. The only way to know for sure what type of connector your router anntena uses is to Google the model number and its specifications.
 
Alternatively it can be unscrewed and examined in pictures before buying one.

    Advice: Use a WiFi tool like Wifi Manager to measure and record the “before” signal at several locations. Then measure after any antenna change. Not all routers behave predictably to higher-dBi antennae. “Beamforming” and other router features can muddle communications with non-stock configurations. THAT was a frustrating lesson for us.

    using e ASUS RT-AC5300,e 8 stock antennas r quite short,but signal r strong. deciding if to change e antennas to 12dBi RP-SMA dual band type. will it help to boost signal further?

    need advice. thanks

      Hi, do you have the antenna part number or model # or the link where i can buy it from? this would be very help full. i have the RT AC 3100 and buying 9 db antennas from power supply did not work. Much appreciated
