"Richard Harrison" wrote Similarly, all the energy can be transferred through the electric field with zero magnetic coupling. Imagine two separately shielded coils. Now, use a coupling capacitor to transfer the energy from one coil to the other. Voila! E-field transfer with zero magnetic coupling. It`s no myth. It`s a fact. Best regards, Richard Harrison, KB5WZI I wonder how the gurus 'splain the different behavior of vertical vs. horizontally polarized antennas, where E field determines the way signals reflect and form the pattern. If E and H fields are so "inseparable" there should be no difference, right? They are ignoring behavior of E and H fields within the near field of antennas and workings of the shield. Another example of shield's performance was when I had small shielded loop next to the Beverage. The combination gave better S/N performance and better signal levels than each of them alone. Again, shield performing shielding function in the vicinity of near field of both antennas. Loops were tunable and performing as an antenna, shield was shielding from the near by interference and providing symmetry. FACTS - verifiable not subject to wild speculations about current crawling around the edge to inside of tubing, or antenna inside of electrostatic shield quitting to work as antenna because of "W8JI shield is antenna teachings". -- Yuri Blanarovich, K3BU, VE3BMV |
