PA1B Accurate 43 dB Attenuator
The PA1B 43 dB attenuator has a excellent accuracy, because each section is built with 6 resistors.
This very accurate attenuator is be very useful in accurate measurements in dB in the shack.
The line up of the attenuator sections, from 1 dB at the input, to 20 dB at the output gives an excellent power distribution.
The attenuator is easily built, with good available resistors from the E12-series.
The attenuator is fast to operate in CW contest QSO’s with low power, because of the combination of the sections of 3 dB, 7 dB and 10 dB
