The base of the Model 6509 loop antenna contains a type N female connector and a manually switchable four-band transformer. The transformer gives the antenna greater efficiency resulting in a better conversion of power to field strength.
Every loop antenna is individually calibrated in accordance with the IEEE-291 Section 2.3.1 methods, using NIST traceable equipment. By knowing the actual antenna factors and performance characteristics of an antenna instead of typical data, you can more accurately measure field strength in your tests.
