ltAP LTE6/7 Antenna Switching in Automotive Setup

Greetings!

Long time user of MikroTik routers and switches, but am just getting into more of the wireless applications. Recently is that of my truck, for which I have chosen to work with the ltAP LTE7 Kit (US bands). The same application could apply to anyone on the LTE6 card/kit.

I'm trying to see how much I can pack into this single system, so my goal, while potentially flawed in its vision is to do the following:

  • Utilize one miniPCIe slot for the R11e-LTE7 card, and the other for the R11e-LR9G (LoRaWAN 900MHz) card.
  • With a single LTE7 card, determine a method in which I can switch 2x2 MIMO antennas for 4G/5G connectivity (4G preferred given most connectivity is away from urban areas).
    • The reason for this is that I want a low profile ~5dBi antenna while driving in high winds, but a higher gain while parked that I can adjust according to location and that will not always be plugged in.
    • The idea is to either swap antennas or to find a method in which I can simply swap the physical connection (following a poweroff).
      • This thought arose because of the differences in antenna cable connections, but also because I will have a static mount off of my roof rack for one. If I can simply swap out antennas with the same adapter and 2x2 connection - excellent.

My fallback is to simply just go with two R11e-LTE7 cards and two separate antennas and utilize another method for my LoRaWAN gateway.

I was curious if anyone has seen a method that would work to allow me to create a physical switch for the antennas (again, it would require a power cycle and not be a hot swap given MIMO) while also introducing as little noise as possible.

Cheers!
