UHF Kosmic SuperQuad (9.75x9.5) NO Refl. Kosmic SuperQuad 4-Bay (if NO Reflector) analyzed using 4nec2. Dimensions from EV's Kosmic SuperQuad thread: http://www.dtvusaforum.com/dtv-hdtv-reception-antenna-discussion/8629-kosmic-antennas-superquad-4-bay-bowtie. UHF Raw Gain = 9.1 to 12.2 dBi and SWR (300-ohms) under 3.5. Hi-VHF Raw Gain = 3.7 dBi and SWR (300-ohms) under 4.5. BowLength = 9.75-in (AWG8), Bowtie Spacing = 9.5-in, Tine Separation = 5.0-in.  Simulated SOURCE wire. Feedline Separation = 1.5-in, except 1.25 at Crossovers (AWG8).  Crossovers = 4.75-in from Outer Bowties. Date(s): 2 Mar 2010. Album by holl_ands. 1 - 16 of 16 Total. 24545 Visits.
