Ham Radio - An end fed folded dipole experiment. Part 1, the idea and design.
I see either a flattened/stretched out full wave loop or a shorted 1/2 wave balanced line.
I agree, but if the feed currents are out of phase then the field will cancel just like a parallel transmission line. If he feeds it with a Balun, and the current in both sides is in phase, then is should behave like any other end fed half wave antenna.
I is for current Z is for impedance
Hmm... Seems to me that the theoretical impedance of a shorted half wave is zero..
You mean short both ends and feed it with a balun ??
I was thinking that he should leave the far end open. If the current on both wires is in phase, then it should radiate just like any other half wave antenna.
Go look up a c-pole from years ago.....
Is it possible to use the correct terminology? By definition, a DIPOLE is a BALANCED, CENTER-FED antenna; it has an equal length of wire on both sides of the center insulator/feedpoint.
Thus, an "off-center fed", while being an antenna, is NOT a dipole. In fact, it's a WINDOM antenna.
And an end-fed is a random wire or longwire antenna, NOT a dipole.
Exactly - all it would achieve is to increase the *wire size* a smidgen.
