Hi I need to know how mutch wire 14 gauge can transmit by watts from hf on my
base yaesu ft897

If your antenna is fed with 50 Ohm Co-Ax, 1000 Watts would produce
223.61 Volts and 4.47 Amps RF at the feed point. Along the antenna, I
expect voltage to increase and current to decrease as you move away from
a 50 Ohm feed point.

I think a 14 gauge wire should be OK for the antenna, but DO NOT TOUCH
IT. It might burn your finger off.

But what are you really asking? I understand the FT-897 has a 100 Watt
transmitter. A 100 Watt transmitter would produce 70.71 Volts and 1.41
Amps at the 50 Ohm feed point. It might not burn your finger off, but
would cause a serious burn.
