UHF Fractal Pisan-Cross UHF Fractal Pisan-Cross analyzed using 4nec2.  [Only Mod2 shown below.] Named after: http://en.wikipedia.org/wiki/Pisan_cross Mod0 version adds GW500 Simulated SOURCE Wire to close the Fractal: non-symmetric, disfunctional Antenna Pattern. Mod1 version uses centrally located GW487 as Simulated SOURCE Wire: symmetric, but disfunctional Antenna Pattern. Mod2 version adds GW501 to interconnect Left and Right halves of the Cross: symmetric, SWR Max=4.1, usable 5-10 dBi Raw Gain on many channels, but Raw Gain Holes on 470, 566 & 698 MHz. Mod3 version comments out GW238 & GW487 so only GW501 interconnects Left & Right halves. Eliminates Raw Gain Hole on 566 MHz, but SWR Max=5.8 needs improvement. Date(s): 5 Aug 2013.
