Common mode filters

This afternoon, I will be taking my Novice exam. So in preparation of being allowed to transmit, I decided to create a barrier for HF. I did so by making a number of loops (7) in the coax cables, just above the ceiling. These loops act as coils and they prevent high frequency signals – that might run over the mantle of the coax – from entering the shack.
