Web15 jul. 2024 · A 20 meter vertical antenna with tuned counterpoise. This weekend has been outstanding on Hawaii Island. Weather conditions were partly sunny and a bit cooler, thanks to the return of gentle trade winds. Most of the vog (volcanic smog) has been blown off and most of us can finally breathe normally. WebAntenna modeling suggests that the impedance is closer to 1800 ohms depending on the "counterpoise" length used. As the "counterpoise" itself approaches a half wavelength, the impedance approaches 5000 ohms. In the graph below I have plotted what MININEC predicts for the impedance of an end fed half wave antenna versus the "counterpoise" …
WebIt’s a great antenna to fling out of a window for a low profile ham station. It’s often easier to get the main radiating part of the antenna (the centre of the half-wave) higher than it would be for a doublet or dipole as there is no feeder to support. Multi-Banding. There are two popular ways of producing a multiband EFHW antenna. WebFeedline Lengths: The feedline length is also an important part of a "friendly" antenna design. When calculating optimum lengths, we must use the velocity factor of the feedline. This depends on the spacing of the wires of Ladderline (true Openwire). In general it between 0.95 and 0.98.
