Self-terminating F Adapter Options

Self-terminating

F Adapters for

RG-6 Hot

Standby

Systems and

Drop Cables

The 75 Ω self-terminating F adapters (STFA) crimp onto the RG-6 cable. There are

two types of self-terminating F adapters:

A Modicon 52-0411-000 model for quad shield cable

A Modicon 52-0399-000 model for non-quad shield cable

Both of these self-terminating F adapters have a return loss of 22 dB, a frequency

range from 100 kHz ... 30 MHz, and an insertion loss of 0.03 dB.

If you are using RG-11 cable, these crimp-on self-terminating F adapters cannot be

used. For RG-11 drop cables, use the 52-0370-000 F to BNC Self Terminator and a

52-0164-000 BNC to F Adapter.

Warning Labels The self-terminating BNC adapters require warning labels, which promote proper

connection and disconnection practices. Modicon MD-9423-000 Hot Standby

Processor Warning Labels wrap around the cable near the self-terminating BNC

adapters; connect/disconnect instructions are provided on both sides of the label.
