[TowerTalk] FW: 2nd C31XR on Europe?

[n4kg@juno.com]

Another simple trick would be to add a triband dipole
above the C31XR, parallel to the boom.  That way you
would ALWAYS have an antenna at +/- 90 degrees
to your big beam.  Be aware that there may be some
interaction with the boom of the tribander which could
diminish the effectivity of the dipole some.  If you have
some extra mast above the tribander, give it a try.

Of course another one or two tribanders at 40 ft is still
advisable.  Remember, NO SINGLE antenna height
will cover ALL the angles supported by the ionosphere,
especially now that high sunspot activity has returned.
