Many more antenna sales today. We sold out of the amplified indoor antennas so some people have been getting the cheapies.
And you can expect quite a few returns on Monday because people couldn't get them to work. Some because they bought UHF antennas that can't get WXXA on channel 7, some because they're too far from the transmitter for any indoor antenna and many because this is the first time they've tried to receive digital channels OTA and they don't realize that it's a bit more complicated than analog was. So they'll connect their new antenna, set the TV on channel 23 and wonder why they don't get anything.
I watched the YouTube video Chris Miller linked to. It was good for a chuckle. It's a 4-bay bowtie with no reflector. UHF, although it might pick up some high VHF in a strong signal area. Then the guy didn't even try to aim it, just dropped it behind the TV.
If I were in a panic to receive WXXA within about 30 miles of the Helderbergs and didn't already have a good antenna system I'd probably experiment with a cheap UNamplified rabbit-ears-and-loop antenna such as the Radio Shack 150-1874 and a long enough coax to put it wherever was best for reception, probably as high as possible. Then I'd use AntennaWeb to find the direction to the station from me and adjust the rabbit ears using How to use Rabbit Ears. Or I'd build a folded dipole out of twin lead, cut to the right length for channel 7 from plans here. For the mathematically challenged, the magic length for ch. 7 is 80.5 cm or 31.7" (32" is close enough).
