As owner of http://www.dennysantennaservice.com We have seen antenna sales increase by 300% in 2006, mainly do to the introduction of digital HDTV. Many of our customer's are even turning off their cable/satellite. Choosing the proper TV antenna for a particular location is the main issue. People have a tendency to purchase an antenna that's too small to do the job, digital reception is all or nothing. Also, their is a misconception that all digital-HDTV broadcasts are using the UHF (14-69) band to broadcast their signal. Currently most are because the VHF band (2-13) is full and is being used to broadcast analog signals. However, in February of 2009 the date set to turn off all analog signals things will change. There are only a handful of broadcast markets across the U.S. that will be 100% UHF. This means if you purchase a UHF TV antenna now, chances are you will loose the ability to receive a portion of your digital channels after that date. My best advice is to purchase an antenna that is large enough to be certain it can easily receive all of the digital broadcasts even under poor reception conditions and one that is VHF and UHF capable, unless you are absolutely certain all of your stations are now and will be UHF after the digital transition is complete. You can determine what channels your station are currently broadcasting on and what channels they plan to be on after the deadline by visiting, http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-06-1082A2.pdf
As long as the antenna is of a certain size and location homeowners association can't restrict the installation see http://www.fcc.gov/mb/facts/otard.html
