Can One Rogers RO4003C 1100x350mm Double-Sided HF PCB Replace Spliced Antenna Sub-Boards? 1. The short answer Yes. When a single radiating aperture, feed network or sensor array is longer than a standard board and must stay electrically continuous, one Rogers RO4003C 1100x350mm double-sided HF PCB removes the connectors and splices that quietly degrade large antenna designs. It is not the che...
