The Rhombic antenna does not support your thesis. On the contrary, I just whipped out an EZNEC rhombic without taking any special care. I copied it out of The ARRL Antenna Book, 20th edition, page 13-13. I only installed ten zero ohm loads, but clicking on "Load Dat" clearly shows the phase shift in the traveling wave current along the wire. http://www.w5dxp.com/rhombic.EZ Sorry, a rhombic won't run on the free demo version of EZNEC. -- 73, Cecil http://www.w5dxp.com |

wrote: Any idiot can falsify a posting. Well, are the standing waves falsified? This is a "traveling wave" antenna, is it not? Presumably any idiot can figure that one out. This, of course, has already been answered by me in another posting. Perhaps you want to look under the bed for idiots there too. ;-) I don't mind being called an idiot, it elevates me in this thread! |

This is just too, too easy! :-) I've just discovered that this "copy" from the ARRL The ARRL Antenna Book, 20th edition, page 13-13. must be quite a departure from reality. In outer space? Well, I trust Cecil hasn't mislaid his glasses once again, performed another math error, or tried to use his car keys to get into the house; but when we substitute his former 1/200th wavelength above ground, this antenna clearly exhibits a SWR of 1.33. Of course, it can be jimmied back into outer space in an effort to suppress evidence of standing waves, but like the Ghost of Christmas Past, those chains will still rattle poor ol' Cec'. (Will he give Cratchit the day off?) Cecil's clever crafting can always be mined for simple problems. Pay dirt every time. Now that I have been exposed for what I am, I can full well expect a lump of coal the size of West Virginia in my stocking. I'm going to need a larger mantle. :-( 73's Richard Clark, KB7QHC |
