    Build a Large DB8 HDTV Antenna: Big Bertha

    Is there any reason the height could not be doubled to create 2 6 bay antenna's?All my reception is edge 2 due to local geography. Right now I am getting 100% signal on some local towers that are 4.9 and 7 miles away. I also do get some very good fringe reception at 100 miles out right now. I am however sure that is due to change once the leaves are back on the trees. I have currently been testing with an old Realistic antenna. Currently I have been looking into the Antennacraft HD-1850 and the Winegard HD8200U. I figured deep fringe antenna's with their large surface area would would increase my chances of consistent reception.Sounds like building the equivelent of a DB16 would be cheaper than buying a new DB8e. It might be over kill. However you cant beat surface area.

    Appreciate the info. I am on both AVS and TVfools forums. I have done a 360 plot for signal strength at 5 degree intervals. Using an Avermedia stick plugged into a Dell Precision M6600 without a preamp on the antenna. I have geographical charts created from here http://www.heywhatsthat.com/profiler.html to show what is in my line of site. I have also checked tower heights and transmitter heights for my local towers. Since doing that I have added a RCA preamp to the antenna. I am however getting 100% signal strength according to the meters on the Avermedia and the one on my TV when I run the cable to its tuner. This includes ABC, CBS, NBC and the CW. Fox is the only problem transmitter as it is 66 feet lower and brings abstractions in the way. It was suggest that I tilt a DB4e bac...see more »Appreciate the info.

Fox is the only problem transmitter as it is 66 feet lower and brings abstractions in the way. It was suggest that I tilt a DB4e back in an attempt to catch that signal. I got to looking at this design and thought perhaps a larger antenna or stacking 2 of the ones shown here but with the upper one tilted back may be a plausible way to go to capture more signals. The problem is that until the leaves are on the trees I will not know exactly what signal strength is going to be. My suspicion is that I will receive a significant drop off. Thoughts? Thanks again.
