This SWR meter consists of a meter main unit, a high frequency coupler, and a power supply.
As you know, it is a high-end high-precision SWR meter, a pass-through high frequency power meter.
All functions are working and the meter lighting is beautiful.
By using an optional high frequency coupler, a wide frequency range can be supported. 
SWC-1 for H.F. range coupler is not included.
