Using TLW a while back, I was modeling a 1/8-wave line and it looks like no
matter what the termination Z at the end of 1/8-wave line, the Z seen at the
transmitter is always the line Zo. Depending on whether the line is open, a
short, or somewhere in between, the magnitude of reactance varies greatly as
does the line SWR, but the Z seen by the transmitter will always be fixed at
Hypothetically, a length of say...RG-58 in odd multiples of a 1/8-wave would
make a great dummy load on paper with exceptionally high return loss when
the termination is either a short or open. However, I'm not sure how
various transmitters would take to a Z of 50 ohms where the reactance
component radically changes between an open or shorted termination but the
power dissipating resistance portion is only a few ohms.
