Two corrections:

An other source specified the stainless steel resistivity as 43E-8
ohm/m


The unit of resistivity is of course ohm m (not ohm/m).

With a 1500 W transmitter, the losses are about 1 W/m, this should
help melting any frost accumulated on the wire during a cold night:-).


With 50 % efficiency (-3 dBd gain), the losses are about 800 W and
when divided evenly along 80 m will give 10 W/m (not 1 W/m), which in
addition to frost will also melt ice and keep the birds away :-).
