A hamstick on 40 meters, if you do everything right, is going to have an efficiency of around 10-15%. You put 100 watts into it, and it'll radiate about 10 to 15 watts.

WebCompute the approximate antenna length for the center frequency of the range for which you are trimming. In our example that would be a trim for about 14.287 MHz, or a dipole length of about 32.75 feet (32 feet, 9 inches). Cut the dipole wire to be a little longer than the computed length – it’s easier to cut wire than to extend it.
