Max BR2 Pro Antenna Connectors

The antennas for modem 1 are labelled 1A, 1B, 1C and 1D. Which one is for Main and Aux? I am using a Parsec 11 in 1 antenna and it is recommended to connect in pairs as follows:

Antenna Cable/ Router Connection
LTE 1 to MAIN 0
LTE 2 to AUX 0
LTE 3 to MAIN 1
LTE 4 to AUX 1

Thanks.

This is a great question! I have a Waveform MIMO 4x4 Panel and I connected to 1A, 1B, 2A and 2B, but my cellular speeds were cut in half. I reached out to Waveform for guidance and was told to play around with it to figure it out. I’m curious if anyone else had any input. Thanks for asking this question.

Hello @JO3
I use the Waveform 4x4 with a MAX BR2 - I have found it works best to use either Cellular 1 [1A-1D] or Cellular 2 [2A-2D] for the 4 connections, not splitting the 4 antenna inputs across both cellular antenna inputs.

Here is the antenna connection I use successfully - (referenced on the Waveform site with a visual). https://www.waveform.com/a/b/guides/hotspots/peplink-max-br1-pro-5g

Looking at the back of the antenna (silver side) - from left to right - connectors = 1, 2, 3, 4
Looking at the (either Modem A or Modem B) from left to right - A, B, C, D

Connections are:
1 → A
2 → C
3 → B
4 → D

Hope that helps.

Thanks. In my case I wanted to split the antenna up, which Waveform said should be okay, but I found it wasn’t. I ended up running a 40G into my attic and now have good signal for my second 5G card in my MAX BR2.
