Hi guys,   I tried to model a v shaped dipole yesterday and was surprised by the results.  I'm looking at a dipole with the ends bent back toward each other rather then an inverted vee.  I started wi

Gary, the pattern of the basic dipole will be the same (slight differences), but the gain and the impedance at the feed point will be down and the resonant frequency will rise slightly...  How much t

the entire antenna is all in a flat plane? so it's looking sort of like a big "C" Most of the pattern is determined by the middle of the dipole, so bending the ends doesn't do much other than change

I didn't do a very good job of describing the antenna.  I'm not really folding the ends back into a C.   I'm making a flat V.... like an inverted Vee but with the ends horizontal rather then drooping

Oh yeah.. the pattern will be almost identical.. The "phase center" of the bent dipole is about 1/4 to 1/3 of the way from apex to tails, depending on the angle. Think of the far field as being the s

Thanks Jim,   I'm wondering if I can take advantage of this to create a switched, 3 legged antenna that will have the same gain/pattern as 2 switched broadside dipoles.   Looking at the diagram below
