Can WiFi AP and LTE share one antenna?

Hello Peplink community,

I’m using an HD4 on a class-8 tractor (long-haul trucking) with 4x Proxicast ANT-126-002 antennas. This works well in most scenarios, except at some trucking terminals where cellular service is poor. Most terminals have WiFi, which I would like to connect to when I have extended stops. Since my antennas support both LTE and WiFi, I’m looking for the simplest path solution to use those same antennas.

  1. Could I use a coaxial union to effectively connect an LTE port and WiFi port of the HD4 to the same antenna and then “switch” through the HD4 configuration: turn off LTE and turn on WiFi? (and then later switch in the reverse mode?). Would the inactive port perhaps interfere with transmission on the active port?
  2. If (1) is no, might I instead use a coaxial switch in the same manner, to physically switch between which WiFi or LTE I want sent to the shared antenna?
  3. Is there another smarter approach that might allow me to use the same cables and antennas?

Thanks team!
