I'm surprised especially since:
  • UHF signals do not travel as far as VHF given the same transmitter power
  • The majority of DTV stations are now UHF
  • OTA provides free HDTV for which cable providers charge a premium

I would be happy to purchase a 14-51 91XG directly from AD's website.

1.) Aren't yagi-type antennas like the 91XG recommended over bowtie type arrays in areas with multipath issues?

2.) Which has less windload?
  • a vertically-oriented antenna such as a C4 or DB8
  • a horizontally-oriented yagi antenna such as the 91XG

3.) Which antenna type is recommended for double-edge-diffraction reception areas?

Thanks
