The CSM1, pictured below, is used to manage the HiQ Combi antenna. It includes a switch to switch between the Dipole (Local or NVIS) mode, and the Veritical (DX) modes. You can also switch in an optional 100 or 400 watt dummy load, as well as present an OPEN or SHORT (used for OSL calibration).
In addition a matching unit can switch in 94pf to 2900pf to acheive very low SWR readings.
