UHF M3 3-Bay Bowtie - NO Reflector UHF 3-Bay Bowtie [aka M3 (9.5x9.0)] with NO Reflector analyzed using 4nec2. Height=21-inches, Width=20-inches. One Bowtie on the M4 (9.5x9.0) 4-Bay Bowtie Antenna was removed to determine the performance of a SHORTER 3-Bay version. The TOP rather than the BOTTOM Bowtie was removed since it results in a slightly UPWARD tilt (5-10 deg) in the Elevation Pattern in UHF Band. Raw Gain in the Hi-VHF Band on all but the lowest channels was severely affected as the Gain Pattern shifted to the OVERHEAD direction. UHF Raw Gain = 7.4 to 10.6 dBi and SWR (300-ohms) under 2.3.
