Hello there, I am building the InvAmos5 with the new dimensions from the papers. Dimensions of antenna array Due to inserting a two-wire phasing line it is necessary to change some of the original dimensions of single Inverted Amos-5 antenna and introduce the new ones. Here are given all dimensions of antenna both in millimeters and in wavelengths: mm wavelengths A 33 0.27 B 61 0.50 C 61 0.50 D 21.5 0.176 E 21 0.172 F 10.8 0.0885 G 32.5 0.264 (from refl. surface to dipole wire axis) X 102.5 0.840 dw 2 0.0164 (dipole elements copper wire diameter) Overall copper wire length: 8 x 282 mm or 8 x 2.3 wavelengths Reflector solid metal sheet surface: 492 x 369 mm or 4 x 3 wavelengths so if F=10.8mm what about the feeding point ? do I need to shorten the distance there and if I do what will be ? and also I haven't done any balun's til now so what will be the length if I use RG58 50ohm.
