The DY 40 is a SAT amplifier for 4 polarization planes, perfectly suited for the construction of large multiswitch systems. The gain is 30 dB in the frequency range from 950. . . 2150 MHz. The gain can be reduced by up to 20 dB in 2 dB increments using buttons. A slope setting to compensate for the frequency-related cable attenuation is possible up to 12 dB.
Power can be supplied via the trunk lines, or alternatively with the seperate power supply unit DY 70. Mechanically compatible to all PROSWITCH devices.
