While the MAX BR1 MK2 has two cellular antenna connections, MAIN & DIVERSITY/AUX, reading these forums, AUX is not really AUX. For the unit to work, there always needs to be an antenna connected to MAIN, and for improved reception, there can optionally be a separate antenna connected to the AUX connector.
Seeing the AUX connector, put into my head that it would be ideal for my use case to have two antennas. One antenna for normal usage, and a backup antenna for use when the main antenna is not available.
I am wondering if there exists an manual antenna switch that works with cellular frequencies? So that an operator can switch to the auxiliary antenna when the main antenna is not available. While I had hoped for automatic switching, manual switching would be good too.
