I dont know where YOU got your antenna info from....but just because a dipole has wide b/w (low Q) does not lower its gain unless the diameter of the dipole causes the resonant length to be much shorter than 1/2 wavelength... Here's a quiz question: Suppose the dipole could be made fat enough to reduce the resonant length to 0.01 wavelength. How much would the gain be reduced? Part 2: Suppose the dipole remained the same diameter and was reduced in length to 0.01 wavelength. If the conductor were perfect, how much would the gain be reduced? Hint for Part 2: This is easily answered using the free EZNEC demo program, another modeling program of your choice, or a few minutes' reading of just about any antenna textbook. Roy Lewallen, W7EL |
