My trailer has a (5 wire prewire. 2 cell, 2 wifi, 1 gps). My antenna I bought has the 2 sets of cell , and 1 set of wifi.
There is no way to fish any more wires. I gave up. I will use the GPS wire for cell signel.
My question is . The wifi antennas. Is one for sending and one for receiving? If one is for sending then I can put the screw on factory antenna inside the trailer as I do not need wifi outside of it and use that cable for the missing cell. I do need wifi wan though.
If not then I have to use a Y adaptor on one of the cell signals. Will a Y work? (share antenna with card slots) as there is only one modem. Do you need the antennas at the same time for both slots or is the modem using all 4 antennas?
I am more than likely not getting 2 cell cards either but you never know.
