The first is a classic Radio shack (Antennacraft-made) design, now used by Channel Master since CM limited their line significantly. The second is fairly new. The third pic is an old VHF setup for channels in opposite directions so a rotor is not needed. The fourth one is very interesting, a stacked folded dipole with multi-element reflector array. I have seen those but the camera was not handy. The fifth picture seems to show a Zenith on the left, on the right is the good old CM crossfire VHF topped with CM's version of the 4-bay bowtie. Looking through some JFD literature, I noted that the longer elements were not only 1/4 wavelength for low band VHF but were at 3/4 wavelength for high band also. That is how the stacked conical antennas functioned on high band with no short elements. Thanks!
