Best WiFi Antennas For Indoor and Outdoor Use – 2023 Guide

If you’re struggling with poor connectivity and dropped connections, it may be time to upgrade your WiFi antenna. The right antenna can make a big difference in the strength and range of your WiFi signal.

I Will help you to find the best WiFi Antenna for your need by providing a guide for the type of antennas, Antenna dBi gain, different connector types etc.

You can replace your stock antenna with an external antenna to use it indoors or outdoors.

Best WiFi Antennas

What is a WiFi antenna, and how does it impact your wireless network?

WiFi is a wireless technology that lets devices talk to each other through an antenna. So, technically, a WiFi antenna is a piece of hardware that sends and receives radio waves to make a wireless connection possible.

It is an essential component of any wireless network as it helps boost the signal strength of the network. Signal range and data speed depend highly on the antenna.

Though there are other factors as well, but the antenna is the gateway of the signal for a WiFi device, whether it is a transmitter like a router, a receiver, a WiFi adapter for PC, or an extender.

Replacing your stock antenna can improve weak WiFi signals.

Are you struggling with weak WiFi signals? WiFi antennas could make the difference. Every WiFi device, like a router or PCIe card, has some kind of antenna built in.

But there are individual external antennas that can be attached to any WiFi device to increase the transmission and reception strengths.

Now, before we find out the best alternative antennas for your stock antennas, let’s understand about the types of antennas.

Types of WiFi Antennas

Depending on your needs, you can choose from a variety of different types of WiFi antennas, such as directional antennas, omni-directional antennas, and parabolic grid antennas. They can also be categorized as indoor and outdoor WiFi antennas.

Directional Antennas

Directional antennas, also known as beam antennas, are designed to focus the WiFi signal in a specific direction. These are long range antennas, but only focus in a specific direction.

This makes them ideal for point-to-point communication over long distances, such as connecting two buildings or providing a WiFi signal to a remote location.

Omni-directional Antennas

Omni-directional antennas, as the name suggests, can transmit the WiFi signal in all directions. These are the common WiFi antennas that almost all routers come with.

These may not be suitable for transmitting the signal over long distances, but they are good for providing coverage in all directions.

Which WiFi Antenna type should you choose?

It is simple to choose between the two types of antennas, for example: For a door camera to increase its reception, a directional antenna can be used for a point-to-point connection between the router and camera. But to provide wifi connectivity in all directions to connect multiple devices, omni-directional is the perfect choice.

Directional antennas are ideal for:

  • Point-to-point communication over long distances
  • Connecting two buildings or locations
  • Rural broadband connections
  • Wireless backhaul

Omni-directional antennas are ideal for:

  • Providing WiFi coverage to a wide area, such as a home or office
  • Small business WiFi networks
  • Indoor WiFi networks

It’s important to note that there may be other factors to consider when choosing an antenna, such as the frequency band used, the gain of the antenna, and any potential interference in the area.

Now let’s find out the WiFi antennas.

So, I have curated a few options for the best WiFi antennas for routers and PCI cards. I have categorized them based on their types.

Most of the WiFi devices come with detachable antennas, and if that is the case, you can replace or upgrade your stock antenna with other high-gain antenna or you can even attach an external antenna.

Please keep in mind that I only mentioned antennas alone in this post and not WiFi adapters or receivers. You can check the best WiFi adapters here.

What is dBi gain and which dBi antenna is best?

dBi is a unit of measurement used to compare the gain of antennas. It is used to measure the power of an antenna relative to an isotropic antenna, which is assumed to have a gain of 0 dBi.

The higher the dBi rating, the greater the gain and range of an antenna. but it does not mean that higher-gain antennas are better.

High-gain antennas have less bandwidth. The higher the gain, the lower the bandwidth.

WiFi Antenna: connector types

As we have seen, different types of connectors are discussed in the above antenna types. As a result, always ensure that the connector type is appropriate for your application. There are converter cables available for certain connectors.

Different type of antennas connectors

The most confusing connector types are SMA and RP-SMA. So look carefully for the hole and pin to identify them. SMA is with a pin between it and RP-SMA is a hole in its center. Male connector have threads inside and female connectors have threads outside.

ufl and mmcx connectors are mostly used in drones and sma, rp-sma types are used in routers, extenders and wifi cards etc.

Things to consider before buying a new WiFi antenna

  • Always check the connector type before buying a new antenna. Check for the SMA or RP-SMA, as these are the common male female connectors. Otherwise, you need some kind of converter cable.
  • Check the signal gain or DBi of the antenna. Higher signal gain does not mean antenna provide higher range. It depends on your use case.
  • Check which frequency band the antenna supports. Some antenna supports single where as other supports dual or triple band.
  • Check for other features like how long the cable is and whether it comes with a magnetic base, etc.

Each antenna type has its own advantages and disadvantages, so it’s important to understand which is the best fit for your setup before making a purchase.

Mostly indoor antennas and stock antennas that come with routers or PCI cards are omni-directional, but we can also use directional antennas for outdoor as well as indoor purposes.
