1.2GHz Forward Inverse Equalizers are cable simulators and produce a tilt that frequency response is equivalent of coaxial cable character. They are used as a forward input equalizer during station balancing when an amplifier is short spaced to achieve the desired flat input. The dB values and rated high frequency 1218 MHz are printed on the top of each equalizer.
It is JXP series and has two types of thickness. The thickness of A-type is 5.6 mm, and B-type is 4.0 mm.
These accessories can be used for amplifiers, coaxial cable units, etc.
