Local noise such as from motors, arcing, etc, starts out with all polarizations but the horizontal component is quickly attenuated by travel over the earth's surface. The vertical component is not, and therefore is received by a vertically polarized antenna. Because vertically polarized signals are not attenuated when using groundwave mode, AM broadcast stations use it exclusively, or very nearly so. They also use enough power to overcome the noise pickup issue. If you live in a relatively quiet environment, you may not notice the difference, and the vertical will have a very low angle of radiation, good for DX, and will probably outperform the horizontal in that respect. The best of both worlds is to have both antennas available and be able to switch between them as needed. Highly recommended. Bill, W6WRT |
