The Channel Master "Multibow" model 410, a reflective array or "bowtie" UHF television antenna from 1954. It was used for reception of the analog UHF TV channels from 470 to 890 MHz. It consists of four "bow tie" triangular half wave-dipole driven elements fed in phase, in front of a flat metal grill reflector. The triangular shape of the dipoles broadened their bandwidth, allowing it to cover the whole UHF band. The 4 vertical stacked elements narrow the beam pattern in the vertical direction, giving additional rejection of ground noise. The antenna sold for $11.11.
