ChannelPlus in-line attenuators Can be inserted in coaxial cable feeds To reduce signal amplitude levels Model 2506 Provides a 6 dB insertion loss, And Model 2503 Provides a 3 dB insertion loss Combinations of 2506s and 2503s May be used togethe To create attenuators With greater insertion loss These attenuators provide a better, More permanent solution Over using a variable attenuator.
