I often use an 18 m Spiderpole with two loading wires, sloping out from the tip at about 60 degrees. I use 18 gauge insulated wires and run 1500 W. I have not seen any signs of overheating. Current is less through the top part of the antenna so wire diameter is less critical (but the voltages can be very high at the wire ends!). I would, however, use thicker wire on the vertical part of the antenna (AWG 12 or larger). Alternatively, use three or four parallel wires on the vertical section (tied together both at the bottom and top). Space them out around the pole.

You can see a 43 foot version (being tested for the upcoming KH1 expedition) at C6AGU, on I have ran 1000 W on that antenna without issues.
