Be careful when removing the core as it is very fragile!


10 windings were made both top and bottom.
They behave like 100 ohm transmission lines.
Input parallel = 50 Ohms.
Output series = 200 Ohms.




Due to the good low frequency behavior and the capacitive behavior at high frequencies, I have decided to reduce the number of windings from 10 to 7.

2 x 10 turns 2 MHz 2 x 7 turns 2 MHz


Return loss 2 x 7 turns

SWR 2 x 7 turns



Insertion loss measuments:
Left: LOT core Right: FT240-43
