Horiz-Stacked CM4221HD's - RF Combiner Horizontally Stacked CM4221HD's with RF Combiner analyzed using 4nec2. Original 4nec2 file from user balm, modified by holl_ands as noted in the file. NOTE: Charts do NOT include RF Combiner Loss, which is "typically" 0.5 to 1.5+ dB, see: www.antennahacks.com  [Back-To-Back Combiner Loss - divide by two.] BowLength = 7.9-in, Tine Separation = 3.94-in, Approx. AWG6 wire size (0.157" O.D.). Inner-Inner Bowtie Spacing = 9.84-in, Outer-Inner Bowtie Spacing = 8.46-in, Feedline Separation = 1.18-in, with 0.8-in at Crossover (2" from Outer Bowtie), AWG10. 32 Rod Reflectors: 23.6" Long with 1.93" Spacings, O.D.=0.193-in.  Separation from Bowties = 4.25-in. Left to Right Bay Separation = 24.6-in with 1-in Gap between Reflector Rods. Date(s): 28 Dec 2011. Album by holl_ands. 1 - 23 of 23 Total. 2681 Visits.
