If I want to move the LTE antenna outside using an SMA extension, do I have to attach two antennas to the façade or is only the "Mobile MAIN antenna connector" sufficient? If so, how far apart should the two antennas be mounted?

Question

Accepted Answer

I was planning to do exactly the same thing. It worked fine for me with this antenna.
