UHF Cube Corner Reflector (1x1x1 meter) + 8-Element Log Periodic Dipole Array (LPDA) analyzed using 4nec2. [Uses three sides of a Cube with a 5x5-cm (2x2-in) Grid.] Distance between LPDA and Corner of Cube was adjusted for "best" Gain performance. Unfortunately, tuning for better SWR significantly reduced Gain.
UHF Raw Gain = 13.5 dBi +/- 0.5 dB, F/B & F/R Ratio Min = 11 dB and SWR (75-ohms) under 3.5.
Note that it does NOT maintain the excellent F/B & F/R Ratios and low SWR of 8-El LPDA Alone: Raw Gain=8.6 dBi (+/- 0.2 dB), F/B & F/R Min=27.2 dB and SWR under 1.4: http://imageevent.com/holl_ands/zigzaglpa/uhflpda/uhf8elveelpdastubopt
