Default The ultimate tilted monopole

In the words of the great Basil Fawlty "you'll like this one"!

It appears to be believed, by one or two who frequent this NG, that a

tilted
monopole provides more gain and somehow 'better' EM radiation than a
vertical one. However, we've seen that tilting a vertical monopole

distorts
its radiation pattern so it is no longer truly omni-directional in the
horizontal plane. Then why not create an array of such tilted monopoles,
all tilted in different directions, to restore the omni-directional

pattern.

The result is a discone antenna, or a discage like the one illustrated at
http://gvarc.us/GVARCFrames/Titan/Di...ch4life002.jpg. I wonder

what
the 'new-age theorists' would make of this. Does it require the Coriolis
effect to analyse it, or is the old-fashioned version provided by
Schellkunoff & Friis(#) still adequate?



Such a design also appears as a self-supporting HF receive antenna the Navy
mounted on the forward gun mount. I
struggled to find a picture of a ship with one showing but no luck. The
elements were about five to seven feet long and arranged as the OP
describes.
