Hi Rik & LF,
I remember seeing a multi top wire LF antenna with multi wire vertical
conductors somewhere & I found it in the 'Low Frequency Experimenters
Handbook' in an article written by Peter G3LDO. He shows a 4 wire top with a
4 wire vertical feed & describes it as a 'Traditional T LF Antenna'. What I
am curious about is that if it is detremental to have this multi wire
vertical arrangement as you stated, why has Peter shown it in his article? I
have an Admiralty book 'Handbook of Wireless Telegraphy' (1938) which shows
the same type of T antenna with a multi wire vertical section. I have also
seen articles elsewhere (maybe on internet) regarding multi wire verticals &
tops were the wires are in a circular arrangement/format & are presented as
'Cage Antennas & Cage Dipoles' although I believe to increase bandwidth.
The reason I am interested is that I have thought about a similar
arrangement because of my small garden area like Dick.
Comments invited please.

Using multiple vertical wires will increase the antenna capacitance
but also decrease the radiation resistance. I guess that a thing you
don't want.
