The impedance would be +j50 ohms, that is, 50 ohms of inductive
reactance. If you open the far end, you'll see -j50 ohms, that is, 50
ohms of capacitive reactance, at the input.

Hello Group,

If I have an RG-58 coax and it is shorted at the load end. At the electrical
1/8 wave lenght what would be the impedance seen at the other end?

I understand that a shorted 1/4 wave length reflects an open, but was
interested in what happens at the 1/8 wave frequency.
