Tom....

You need about 130 feet to make a good inverted L.  Oh, you can place a
coil in the horizontal leg and get by with that....or you can use a series
capacitor at the bottom to tune it.  But, I do not use a stub in the sense
that I understand you to mean.  At 130 feet you can almost feed it direct
because it is a quarter wave at 160 meters....and of course a half wave at
80 meters.  I have one that is 55 verticle and 75 feet horizontal.  Works
FB with a bunch of radials underneath the verticle part.  I have around 10
random length radials...cause that is what I can get onto the lot.

See the Handbook for more disucssion, but they are a very simple antenna.
