SMA connector for antenna

On the LBAD0ZZ1SE module, the U.FL connector is the only way to connect an external antenna. LBAD0ZZ1SE
can use the SMA rod antenna through the CN1 cable which converts the SMA port to U.FL port. The antenna is
permanently fixed to the SMA connector as per FCC requirement.
