Hi Pete
Concerning a 3/8 wave open end stub.
"The three eights wave line transforms the line impedance into an equal
value of inductive reactance"
Page 25.10 Radio Habdbook-twenty second edition. W6SAI William I Orr.
At another QTH I found the inductive reactance was not quite enough to
get good reflector action. The solution was to go to 75 ohm coax..
Inserted an L network at the shack side of the directional switch to
transform to a 50 ohm match.
Obtained excellent results.
