2 70 dual band yagi

Co-Phasing. Co-phasing or "stacking" has long been a way to get high gain from antennas. Co-phasing involves placing two (or more!) identical antennas either side-by-side or one over top another ("stacking") at a certain distance apart (usually a 1/2 Wavelength or more) and feeding the antennas in-phase.The result is 3 db more than just a single antenna.PG1N's HAM Radio Site - 2m Projects - Omnidirectional Vertical. 2m Projects - Omnidirectional Vertical.
