CAL48 is a 70 cm connection cable designed to connect Wisycom MTP40S, MTP40, or MTP30 transmitters to a PHA48 unit. It terminates with a LEMO 3-pin connector on one end and a TA5-F connector on the other. The lead provides the required physical interface between compatible devices and contains no active electronics. It does not perform signal processing, power distribution, or format conversion; it is a passive interconnect.
