The program outputs dimensions and other data for the rhombic you want. At the end, this info is expressed in terms of x,y,z coordinates (in meters) for entering into an antenna analysis program like Elnec. The metric system has been declared "legal" in the U.S. since about 1870, so maybe it's time to throw away this inches and feet business. Get a tape measure that measures in meters. We're almost in the 21st century Analysis with Elnec of the so-called 'vertical rhombic' (there are published articles advocating use of rhombics rotated 90 degrees, to the vertical, for vertical polarization) shows that it is useless. The pattern is worse than a dipole, even if you place the antenna 100 meters above the ground. I don't know if the authors of these articles ever actually used these antennas in a situation that would determine how effective they really are. I recently found the "vertical half-rhombic" in a U.S. Army antenna manual, however; if anyone has practical experience to share, please do so, it would be much appreciated. A vertical half-rhombic would be a very useful antenna to have and it would be easy to set up because it would be essentially a long wire in an inverted-V plus a ground counterpoise
