UHF "Figure-8" Twin Loops - NO Refl

UHF "Figure-8" Twin Circular Loops with NO Reflector analyzed using 4nec2.

UHF Raw Gain = 5.6 to 7.4 dBi with SWR (300-ohms) under 2.4 [using QICT].

Should use 9.1-in Diameter, QICT (Quarter-Inch Copper Tubing) or larger for
New [470-698 MHz] UHF Band version (SWR under 2.4, -0.8 dB Mismatch Loss).
AWG10 NOT RECOMMENDED for UHF version, since SWR climbs as high as 3.65 (-1.71 dB Mismatch Loss).

So glad I found this site. Now receiving 46 channels (Hamilton, Windsor Ontario, Cleveland Ohio, Detroit Michigan) using loops!
Ty ty ty!
