Forward Equalizers, 74100
These forward equalizers produce a tilted frequency response opposite of that produced by coaxial
cable. They are normally used during amplifier or node installation to counteract the tilt produced by
coaxial cable, in order to achieve the desired output tilt. Each equalizer has a value that indicates
the amount of tilt (in dB) that the equalizer produces from 47 MHz to rated upper frequency. The dB
value and rated upper frequency (450, 606, 750 or 862 MHz) are printed on the top of each
equalizer.
