"Dish" was an outrageous design using a dipole for UHF, stoking a delusion among the band-illiterate. Only good in Metro areas and I bet it was not patented either.
"Archer" Antenna: The plastic things on the VHF dipoles were so that you could adjust them without making electrical contact and skewing results of aiming-spreading. The one knob rotated both loop and monopoles, other knob performed the "hocus-pocus" of impedance-matching combinations.
The plastic ring on the UHF loop added a director and reflector element that was just chromed plastic. I never did understand why a bowtie and reflector was not used on these set-tops instead. Loops had one advantage, not limited to horizontal polarization. The best set-top UHF antenna I ever used was that RS $4.99 set-top two-bay bowtie.
These may have been the last of the indoor antennas that used a switch to alter connections between the elements and have separate UHF and VHF leads.
