Peplink MAX BR1 Classic/Mini/MK2 External Antenna Guide


Looking to get the best possible data rates from your Peplink MAX BR1?

You’ll want to purchase and connect external MIMO antennas to the device’s two SMA ports.

In this guide, we'll:

  • Recommend the best external antennas to use.
  • Show where the SMA ports are located.
  • Explain how to aim the antennas for best results.

In this guide

Using a MIMO antenna outside your building, pointed at the nearest tower, can help you get the fastest LTE data rates possible.

The Peplink MAX BR1 has two SMA ports at the back. These allow for a 2x2 MIMO antenna to be connected to the device.

We recommend two different MIMO antenna options for use with the Peplink MAX BR1:

Best For Most Users

This MIMO panel antenna kit will provide meaningful signal improvement, even if you're surrounded by trees, hills, or tall buildings.

For most users the best external antenna choice for the Peplink MAX BR1 is our 2x2 MIMO panel antenna kit. This antenna doesn’t require line-of-sight to the tower.

Best With Line Of Sight

These cross polarized log periodic antennas are have higher gain and are more directional, but work best if you have direct line-of-sight to the tower.

However, if you have line of sight to the nearest tower, we recommend using a 2x2 MIMO log periodic antenna kit instead. The higher gain on these antennas can get you better performance, but only when you have a straight shot to the tower.

Why External Antennas Are Critical for Improving Data Rates

Most people think that external antennas primarily help you increase your data rates by increasing the signal strength. But that's not the case.

An increase in signal strength is often less important than other ways that external antennas help.

Here are the three main ways that external antennas help you increase your data rates:

1.They Improve Signal Quality

In 4G LTE networks, signal quality is measured as SINR (Signal to Interference plus Noise Ratio) or sometimes as RSRQ (Reference Signal Received Quality).

Improving signal quality has a huge impact on your data rates.

Higher data rates allow your hotspot to communicate using "higher order modulation schemes." That means they can use the same wireless spectrum to send more data per second.

However, there's one big caveat:

In order to improve your signal quality, you need to both aim and shield your outdoor antenna properly. We talk more about this in the next section.

2.They Allow You To Connect On More Bands

Routers like the Peplink MAX BR1 support an LTE feature called "carrier aggregation."

Carrier aggregation allows the Pepwave router to connect on multiple cellular bands simultaneously.

The more bands you're connected on, the greater the bandwidth, and the higher your data rates.

However, many of the higher frequency bands aren't able to penetrate into buildings. Using external antennas allows you to access higher frequency bands, which are often less congested and offer higher speeds than lower frequency bands.

3.MIMO Isolation

MIMO (Multiple Input Multiple Output) technology uses signals travelling along multiple paths simultaneously, increasing both bandwidth and reliability in wireless connections.

MIMO isolation is the antenna's ability to handle several data streams at once, cleanly and without interference, leading to quicker data speeds and steadier connections

Our external antennas are specifically designed for superior MIMO isolation, and dramatically outperform standard built-in antennas found in most home devices.

This means you'll see a more reliable connection with enhanced bandwidth, ensuring smoother streaming, gaming, and browsing with minimal interruptions.

Positioning and Aiming MIMO Antennas

Positioning and aiming MIMO antennas well is crucial to getting the best performance to your Peplink, or indeed any other router.

We've actually compiled a detailed instruction manual to accompany our own MIMO Antenna Kits, where we go into depth on the best ways to aim the antennas.

The goal is to find the best location and direction for the antenna(s), to maximize data rates to the hotspot. It can take a little patience, but can have a huge impact – it’s worth a bit of extra effort!

Before getting started, it's always a good idea to run a couple of speed tests indoors from a device connected to your Peplink WiFi. The results will fluctuate a little, but this is the baseline you're trying to improve.

Now connect the MIMO antennas to your Peplink MAX BR1 via the SMA ports, and go outside with your "test-rig".

With each location and direction you try, run a couple speed tests, and make a note of the results. Here are all the locations and directions where we recommend testing your MIMO antenna:

Where to test your signal

Where to test your signal

Pro tip: Don’t just go to the highest point of the roof! While signal is generally stronger the higher you go, there’s also often more interference. We’ve found it’s often better to mount the antenna(s) on the side of the building where the structure can shield the antennas from interference.

Once you've found the position which gets you the highest data rates to the Peplink router, that's where you'll want to install the MIMO antenna. Go ahead and mount the antenna, run cables inside, connect everything up, and enjoy superior data rates!

Advanced Optimization

If you've gone through the trouble of installing and accurately aiming a MIMO Antenna Kit, you're likely already getting excellent data rates from your Peplink MAX BR1.

That said, there's always more that can be done!

Band locking is a great way to optimize data rates through an LTE router or hotspot. The idea is that you test every different frequency band being received by your device, and lock it onto the band that results in the best data rates.

The Peplink MAX BR1 is one of few lines of routers that allow manual band locking in their web interface - here's a step by step guide of how to do it.

The reason this works so well, is because different frequency bands transmit with different bandwidths.

Generally speaking, higher frequency bands (like 1900 MHz and 2100 MHz) offer more bandwidth but travel less far and penetrate building materials less well than lower frequency bands (like 700 MHz and 800 MHz).

As a result of traveling less far, higher frequency bands tend to be less “congested” - they have fewer users connected to them, and data rates are often faster.

This isn’t always the case though, sometimes a lower frequency band may have better data rates, depending on your location.

This can be quite time-consuming, but often results in significant improvements to data rates.

We'll keep the steps below as simple and concise as possible!

  • Use a computer to connect to your Peplink's LAN network via ethernet, and open a web browser.
  • Enter "" into the URL bar to log into the Pepwave web interface.
  • Login to the interface with your username and password - default username is "admin" and the password is "admin".
  • You will be required to change the password on the first logon.

Step 2: Navigate to the cellular settings

  • On the main dashboard, you will see a number of fields under "WAN Connection Status".
  • Find the cellular option with a SIM card detected, and click on "Details". There's a fair amount of useful and interesting information to be found in this section of the web interface. For now, we're only interested in the band locking feature.
  • Scroll down past "Cellular Status" and "WAN Connection Settings", until you see "Cellular Settings".

  • Expand the dropdown under the active SIM card slot, and change "Band Selection" mode to "Manual".

  • From the list of bands that appears, select only the band(s) to which you'd like to lock the Peplink router.
  • In the example below we've selected all of the bands that are available, you will probably only want to select a subset of the LTE bands.

Once you've selected the bands you'd like to use, reboot the router for the changes to take effect.

Now, lets test each available band in your area, to determine which will result in the best data rates.

Step 4: Test and select the best tower and frequency band

  • Look up your nearby towers. This can be time consuming and accuracy is often questionable - we've listed our suggestions in an article on the Best Ways to Locate Nearby Cell Towers.
  • Aim your external MIMO antenna(s) at each nearby tower and band lock the Peplink MAX BR1 to each band that the tower transmits.
  • Run 3 to 4 speed tests on each band to find the fastest bands. is a great tool for this.
  • Repeat this for every tower in your area, and make notes of the speed test results you get from each band and tower combination.

Once you've identified the best tower and band combination, lock your Peplink to that band, and make sure your outdoor antenna is secured so that it doesn't move in the wind.

The Peplink MAX BR1 router comes in three main versions:

  • MAX BR1 Mini - This version is the "budget friendly" option, and sacrifices an ethernet port, for a total of two 100 Mbps ports.
  • MAX BR1 Classic - The base model, and the one we reference throughout this guide. This has three 100 Mbps ethernet ports
  • MAX BR1 MK2 - This version upgrades it's two ethernet ports to gigabit (1'000 Mbps) and add's dual band WiFi.

All three modems have the same chipset, come with the same management features, and look very similar. For people on a tight budget we'd recommend the Mini version, but for a couple hundred dollars extra, the MK2 version offers some meaningful performance improvements.

The specs below refer to the base MAX BR1 Classic, which appears to be the most common version out there.
