I am at a loss to understand the L Network function in EZNEC + 5.0.
Should one be able to model an L match to a short (or long) vertical
with this resource?

If so, how about an example please?

In the main window, click Help, then Contents. This is the EZNEC manual.
In the manual, locate the Test Drive chapter, which is a tutorial for
using EZNEC. The Test Drive section A Lap Around Track 5 covers L
networks and other features new to v. 5.0. For additional information
about L networks, open the L Network Window by clicking the L Networks
line in the main program window, then press the F1 (context sensitive
help) key.
