Topband: Re: Short Monopoles

[Roy Koeppe]

Asked,


           "I need information (pref. www links or other sources)
describing short monopoles using multiple wires connected to it's top
and fed in phase for increase in radiation resistance. (Used in
LF/VLF)."


Unless you're referring to adding multiple, spaced elements, adding
additional conductors to an existing radiator does not increase its
radiation resistance. Only the feed point Z can be increased in the
fashion of a step-up transformer.
