If I remember my traveling wave antenna theory, he wouldn't necessarily be loosing 3 dB in the resistors. At higher frequencies more of the power radiates before it gets to the loads, does it not? Yes, "more" but not near 100%. A multi-wavelength terminated rhombic loses its reverse radiated lobes and along with them, quite a bit of power. Even on 10m, 110 ft. is only 3 wavelengths long. Averaged over all of HF, I'll bet that antenna loses close to half of its power in the resistors, assuming all reflections have been eliminated by the resistors. -- 73, Cecil http://www.qsl.net/w5dxp |
