Topband: Shunt Feed

[Guy Olinger K2AV]

The difference in an inverted L and a shunt-fed tower would have been
overwhelmed by any differences in the ground/counterpoise systems
underneath. How you deal with ground and radials/counterpoise on 160 is the
1000 pound gorilla in the room with no real competition.

Beyond that, if the bend of the L was supported by the tower, you may have
been mostly using the tower anyway.  One could not evaluate the change
without some estimate of the interaction, particularly whether the *tower*
had good radials when the L was in use, or whether the radials were only
added when the tower was loaded.

If if looked like a simple question, it's really drowned in complications
with make or break outcomes.

73, Guy.
