[Elecraft] KX1 - We need to develop the ideal antenna

I can understand this in a home situation, but for use with a very
lightweight, low bulk portable rig like a KX1 I would use something like
16/0.2, (16 strands of 0.2mm copper, similar to 14/0076).  I wouldn't for
instance hang flexweave from a floppy fibreglass pole, but I've done it with
this thin multi-strand insulated wire. Flat twin loudspeaker wire as shown
in (all?) post-war ARRL handbooks doesn't even need a centre
insulator/connector.  My criteria is:  if it falls out of the
tree/balcony/hotel room window, will it cause damage or hurt someone?
