From the left to the right we see the balun on the ferrite bar, the 4-cage CV and the roller coaster.

Box Antenna tuner 8 bandes
It covers amateur bands from 80 to 10 m in 7 ranges because the bands 14 and 18 MHz use the same position of the switch

Box Antenna tuner monobande 28/30 MHz
Like the 10 MHz mono-band box, this box operates in autotransfo. The permissible power is greater than 200 watts
