I read about 8 bay antennas and the flaws in the 8800 at hdtvprimer.com
Poor feed 8800

8-bay discussion
http://www.hdtvprimer.com/ANTENNAS/TemporaryPage.html
I decided to try what HDTV Primer suggested and used two baluns, 2 equal lengths of coax, and a combiner to gang the 4 bays into an 8 bay rather than trying to make an impedance matching feed.
I used channel master baluns, 3’ lengths of coax, and a 1-2 splitter used in reverse as a 2-1 combiner. The result is higher signal quality, presumably from less multipath, and reliable reception of DC stations.
If I have some time in the future I may work on a feed system with twin lead, but for now what I have works quite well.
