. At your option, you can install an SMA
type RF connector (2a) at the J1 RF port. Or you
can directly solder a suitable antenna, either per-
pendicular (2b), or along the PCB plane (2c). The
PCB provides little mechanical support for a rigid
antenna, hence use only with additional support,
or when the MUDT, together with the antenna, is
housed in a protected (not metal) enclosure.
