MAKE subscriber William F. Dudley Jr. sent us a link to his plans for building a Gray Hoverman UHF Antenna. Why would you want/need a UHF antenna? He explains:
Assuming you get your television “over the air”, i.e. from an antenna, then after the transition to digital television, sometime after February 17, 2009, channels 2,3,4 and 5 will cease transmitting on their old frequencies in the VHF band (approx 52-76MHz) and will start transmitting on new channel assignments in the UHF Band. For example, in the NY Metro area, that means that channels 2,4, and 5 will now be at UHF channels 33, 28 and 44. So even if you never had any interest in UHF before, if you like watching WCBS, WNBC, or FOX television from NY City, you’ll need to be interested in UHF now. Note that these reassignments are true nationwide, though the actual UHF frequency that 2,3,4 and 5 will be reassigned to depend on what other channels exist in that market.
