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 :-).
