Nikiml and 300ohm, would you expect improved reception from a DBGH10n3 over SB? My GH10n3 works great, but it peeves me that there are two peanut whistle UHF stations that I am unable to receive most of the time, 46 miles north in Washington, DC. I am preparing to build another GH10n3 that should be eaiser for most folks to build and hopefully will be lighter than my first. I also want to have it aimed upward to fit conditions at my location. It would not be that much harder for me to add a second vertical bay, without the NARODs and their 3 reflectors in the second. My current SBGH10n3 gets the two available VHF stations 24/7 even during widespread thunderstorms. If it is worth a try, am I correct that the two bays could share the same end reflector rod? Would the correct spacing of phasing lines still be about an inch above the active elements and an inch apart?
