I have been toying with the idea of co phasing 2 DPD 225-400Mhz LPA's. I understand the gain would be about 3 DB by doing this. I also understand that the antennas must be separated by 1/4 wavelength. Should it be a 1/4 wavelength at the lowest operating frequency or the highest? The low being 225 and the high being 400. Also do the antennas need to be separated horizontally or vertically on the mast? Does it matter? Also some insight on the phasing harness would be good too. Looking for alot of info here.
Thanks
