End-feeding dipoles

Several authors recommend against end-fed dipoles because of alleged difficulties in matching to a 50-ohm line. Unfortunately, the "slur" is dropped without a hint of explanation. Other authors see it as simple and reliable, and recommend it with enthusiasm. A parallel tuned circuit with tapped inductor is usually the recommended impedance transformer. In my own experience, matching has always been extremely easy and trouble-free. So does anyone know why this might be thought so frought with problems that its general use would be discouraged? Chuck, NT3G The matching doesn't have anything to do with it. It's the excess common mode currents that I don't like. Sure, they work, but I would never use one if I can center feed the antenna. And I've never really had a case where I couldn't center feed. MK |
