This antenna is a hybrid between a Yagi and a corner reflector antenna. The directors determine the gain on the high channels, while the size of the corner reflector determines the gain on the low channels. It attempts to be a wideband antenna, but in fact it does a mediocre job on the low channels. Although the Yagi/Corner-Reflector is not the best antenna, it is the most common UHF TV antenna, mainly because it can be mounted on the front of a VHF antenna without degrading the VHF antenna.
