Perhaps I might be of assistance by providing some orders of magnitude.

A 1/2-wave stub line, 1 metre (39.37 inches) long constructed of a pair of
polished copper tubes, each 1/2-inch in diameter, centers spaced 3 inches
apart, at 150 MHz (not very far from 2 meters) has the following
characteristics -

Zo = 299.8 ohms.
Attenuation = 0.0024 dB.
As a tuned circuit, Resonant Q = 5800.

When short-circuited -
Parallel input components of Zin -
Rsc = 0.08 ohms,
Xsc = -j*582 ohms.

When open circuited -
Series input components of Zin -
Roc = 1.11 megohms,
Xoc = j*38.6 ohms.

These and many other interesting values can be very accurately and rapidly
calculated, from 20 Hz to 1 GHz, by using program RJELINE2 available, free
issue, from website below.

Contributors to this newsgroup, who by no means are lacking in intelligence,
may then be able to get their feet on the ground.
