UHF Quasi-Periodic (KISS) with 4-Panels (1x1-m each) and 8-Element Log Periodic Dipole Array (LPDA) Feed analyzed using 4nec2. Distance From Corner to Shortest LPDA Element, x=34.61-inches.
UHF Raw Gain = 17.3 to 19.3 dBi, F/B & F/R Ratio Min = 13 dB and SWR (75-ohms) under 2.4.

To simplify the model (and speed up execution times), a simple Horizontal Wire Model was used, spaced at about 2.8-in (7.1-cm). Best performance [esp. F/R & F/B] is provided with 1-2 in (2.5 - 5-cm) vertical wire spacing, such as Grid style Animal Cage/Fencing material.
