Best 2.4 GHz and 5 GHz Antennas for WiFi Dual Band
Does your router have dead WiFi spots or lack transmitting at a distance?

Using a better antenna is a cheap and easy solution that can boost signal quality.

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 an 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 larger 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 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.

A wireless USB adapter with a good antenna would be best for a laptop or desktop computer.

Things To Check First

Some 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 for a match before buying one.
