Hi-VHF Crossed FD's - 2TL=QWL+HWL Hi-VHF Crossed Folded Dipoles (FD's) Yagi [Coincident, NO Offset] fed by two Unequal Transmission Lines, Quarter-Wavelength and Half-Wavelength long respectively to provide requisite 90-deg phase shift between FD's for Right Hand Circular Polarization (RHCP). Poor Cross Polarization Loss on higher Hi-VHF channels and lack of LHCP suppression (Multipath) from REAR. Date(s): 4 Feb 2012. Album by holl_ands. 1 - 25 of 25 Total. 2247 Visits.
