Ooops !
A little overkill then ? :-)
I did not know that it was a short piece of wire in mid air..
I am not very familiar with QRP equipment  :-)
But for long runs in crowded places the wire is a good choice,
even for a 3Kv supply.  I once tried RG213 for 3Kv DC and got
a flashover. The cable was of unknown quality from the far east,- but
after that i have been a regular customer in the racing shop.
I agree with Jim: for your project you may use almost anything,
