Hi-VHF (+UHF) Twin Rectangular Loops Hi-VHF (+UHF) Twin Rectangular Loops (aka "Shorted Rectangle") analyzed using 4nec2, assuming Picture Metal Frame Size = 36-in H x 24-in W. Hi-VHF Raw Gain = 4.7 to 5.5 dBi and SWR (300-ohms) under 2.7. UHF Raw Gain = -8.0 to 0.0 dBi is Low but usable Gain for Strong Signals.  Even better 45-deg off-axis on many freqs.  SWR (300-ohms) under 2.7 [Excellent].
