MAX BR1 Pro 5G: Which Two Cellular Connectors Are Transmit?

It is my understanding, from comments in my Confusing, Disappointing Peplink Pepwave Equipment Performance thread, that only two of the four cellular antennas are used for transmit?

If so: Would you be so kind as share with me which of the two, of “Cellular A” through “Cellular D,” those are?

Reason being is we’ll be using a pair of XPOL-2-5G antennas, mounted one atop the other. I expect to separate them by a few inches–in part to lower wind load and in part to achieve a bit of space diversity. If I knew which two connectors were transmit I could make sure to get one transmit on each antenna.

Or am I over-thinking this? I sometimes do that :slight_smile:
