2.6.5 Loop coupler.
The loop coupler must be used in installations where the standard antenna ranges are not sufficient. Special
designed aerials can then be made. Please contact Hi Sec International for further documentation and advises
in these cases.
2.6.5.1 System characteristics.
The High Performance Adapter is only required when the loop aerial is close to a metal door or door frame. Most
installations consist of just the 90T CSC interface, the 90T CLC loop coupler and the loop aerial.
