The screens behind the bowties.

In 2009 the FCC narrowed the UHF TV band from chs 14-69 to chs 14-51. The 700 MHz band chs 52-69 was turned over to wifi and local public service uses. The sensitivity of the DB8 peaks in the 700 MHz band, which is no longer TV. The DB8e peaks below 700 MHz, in the current TV band. Many of the UHF antennas on the market are optimized to the pre-2009 TV channels, and thus miss an opportunity to increase sensitivity by narrowing their target bandwidth. So the DB8e is not only newer, it is more sensitive than the DB8.
