Redshift antenna project

The layout of a center frequency 2203.1 MHz antenna is presented. The four to one taped layout was photograph reduced and a single section was etched. Initial impedance and frequency mismatches were corrected, and impedance plots of each of the two sections are shown. With the 2203.1 MHz layout as a reference, initial layouts were made for the remaining two frequencies 2117.7 and 2299.7 MHz, and single sections were fabricated.
